ERMINE
Ermine Wood Coating
Wood is one of the world's most important natural resources. Forests are renewable, fortunately. With proper arrangement and efficient utilization, the wood industry has a continuous source of supply. Wood Coatings lend the finishing touches to a wide variety of products manufactured from wood.
These coatings enhance the appearance and provide protection for home and office furniture, kitchen and bath cabinetry, wood flooring, wood window and doors and many other factory-finished building products. At Sansui Paints, we enhance the natural beauty of wood even as we sheath it with classy, protective polish.
Sansui offers Ermine Wood Coating which enhances aesthetic appeal and provides surface protection that improves the durability of your furniture. Ermine Wood Coating caters to the specific needs of a range of wood products, keeping in mind the varied susceptibilities of wood.
Ermine-LIAU:
A Water based coating that affords minimum grain rising to your wood. It is new generation coating with LOW VOC, keeping in mind of low emission, the one pack for easy sand ability with fast drying abilities. We offer two different qualities in water based, the difference between both is the difference of resistance on the surface, one is with a lower resistance (slightly better than NC Lacquer and another one based on Acrylic system which is highly scratch and chemical resistance) the benefit of using a water based system is firstly it does not produces strong fumes like a solvent based system so in case there is an on-site work and people have to spray right at the very place.
One-Minute Series:
As the name suggests, this series offers incredible drying speeds, with a one pack, and alternatively two pack water based polyurethane solution. It facilitates easy use, through its good, non clogging sand ability. The One Minute Series is ideal for harsh conditions, and offers excellent resistance against UV emissions, humidity and generally wet ambient conditions.
Ermine-PU:
Ermine PU is an easy to use solution, which offers exceptional resistance to chemicals and the harshness of cold temperatures. Ermine PU is a trouble-free coat, that sand without clogging sandpaper and boasts of superior drying- with touch dry capability of less than 10 minutes, and a recoat ability of 3 hours. The two-pack fast drying non yellowing PU Coating, offers your wood a high gloss, clear, metallic finish.
Polyurethane:
Polyurethane varnishes are two-pack products: one base part and one hardener, that are designed to be mixed in given ratios immediately prior to use and that cure by means of providing a surface with, chemical reaction.
Wood finishing and wood care is an important when building any structure, Biggest Challenge in finishing the wood is moisture contents and its highly porous and hygroscopic cell structure, also wood enzymes, oils, acids (Tannin, Linguine) which discoloration of the wood.
A Coating System Comprises mainly of: Sealer / Base Coat, and Top coat
Wood coating base coat has primary function is to seal the porosity, seal the surface, and seal the voids impregnate dip.
Using polyurethane varnishes gives woodwork a special level of topcoat that cannot be rivalled by single-pack varnishes in terms of surface hardness, chemical resistance and mechanical strength. The extensive range of Sansui polyurethane basecoat and topcoats cater to all manner of furniture coating needs with excellent aesthetic results, mechanical strength, chemical resistance, quick drying properties and extremely short working times.
Varnishes from the polyurethane series are advanced products that are suitable for finishing furniture on an industrial scale and, to date, are the products most commonly used for coating chairs, frames, cabinet doors, joinery, wood flooring and furniture in general.
Today's coatings industry can really make your head spin, and we don't mean from the fumes. The list of coatings choices for end users is seemingly endless; we identified challenges at three levels,
1) Foundation - Surface Sealing, Equalizing, and Discoloration:
Wood sealer is any product applied to raw wood as a protective coating. This protective coat may accomplish a few purposes, including:
-
Protecting the wood from water damage
-
Decrease the harmful effects of UV rays
-
Preserve the beauty of the wood
-
Provide a coat before other finishes can be applied
-
Extend the lifespan of the wood
2) Surface Sealing & Equalizing:
Wood is a thirsty product. It laps up every liquid that’s spilled, poured, or brushed onto it, except sealer. So, when working on porous woods, it’s nearly impossible to get a smooth coat without first filling the pores. cell structure differs with type of woods, these void spaces need to be sealed properly, in order to reduce coats of coating, We Offer two types of polyurethane sealer coats,
Sealer is a general term for a wood finish that closes the wood's pores and protects the surface of the wood. Once you apply a sealer, nothing should penetrate the wood.
3) Equalizing:
Role of Sealer coat, is to seal the surface, fill the void space, a sealer is absorbed by this porous substrate, resulting uneven surface, which is mixed of polymer and wood, that needs to be properly sand, hence a sealer also needs to have better sanding properties.

General information:
PUR lacquers should not be used and dried at product and room temperatures below 18 °C and below 40 % RH, ideal values: 20 - 25 °C, 50 - 65 % RH. Deviations lead to problems with drying or, as may apply, hardening. In order to avoid adhesion problems,
sand the polyurethane lacquered surfaces before applying fresh lacquer and apply lacquer to the sanded surfaces as soon as possible. Mixed residues from the previous day must only be used as a 10- 20 % aggregate in a fresh lacquer/hardener mixture.
Old lacquer/hardener mixtures impair the surface quality (adhesion/stability). Freshly bleached woods must be dried for at least 48 hours at 20 °C before being coated with PUR lacquers.
If stored correctly (at least 20 C/room temperature), complete hardening of the coating is achieved after a week.

Coating Coverage Brochure
PURPOSE
This section provides information on the key factors effecting coating coverage and costs. Consideration is also given to “stretching” a coating with thinner, and comparing costs per litre.
INTRODUCTION
The purchaser of protective coatings is responsible for selecting the most economic coating available which is suitable to achieve the required protection. The coatings field is complex and knowledge of coating calculation techniques and interpretation of data is required in order to make the appropriate choice.
VOLUME SOLIDS
Most liquid coatings contain a solids portion and a volatile portion. The solids portion consists of the binder, normally oil or resin, together with colorings and functional pigments, extenders and additives. The volatile portion is the solvent or thinner that merely liquefies the solids sufficiently to carry them onto the surface being coated. The solvent then evaporates, leaving behind the dried film of solids, which provides protection and decoration. The coating user is most concerned with this remaining film volume or thickness because it is this, which provides the desired hiding, gloss, weather resistance, colour etc.
When selecting a coating the key is how much area will the solids cover per litre after the volatiles have evaporated?
SOLIDS CONTENT BY VOLUME OF SURFACE COATINGS
Solids content is a theoretical calculation based on certain assumptions concerning the densities of the raw materials used in paints. In practice, the solids content obtained can vary greatly from its theoretical value because of change in the following:
-
Densities.
-
Temperature effects.
-
Small differences in the physical condition of the paint.
-
The methods and conditions of application.
In addition, film contraction, solvent-retention and volatility of low molecular weight polymers can all contribute error. The determination of volume solids by ASTM, is difficult to calculate and large variations have been observed in practice. For these reasons the volume solids values given in this manual are determined by a method which corresponds to ASTM method DZ697 and ISO 3233 with a slight modification for use at practical film thickness and with usual curing and hardening requirements.
The calculations obtained are generally higher than the theoretical calculated volume solids, but the method approximates the spreading rates obtained under ideal conditions. Volume solids should not be used to gauge practical spreading rate as so many other variables have to be taken into account. For this purpose please use the data provided later in this section.
“STRETCHING” A COATING WITH THINNER IS A MYTH :
Adding solvent or thinner to the liquid coating adds nothing to the hiding or spreading rate of the coating solids as the extra solvent evaporates. Instead, extra solvent merely increases the coating cost by the price of the thinner and increases application costs by the additional labor time required to mix the thinner into the coating. In the case of baking systems, the cost is increased by the greater amount of oven heating required to remove the thinner. Adequate volume solids, not thinners, are the key to proper coverage by a coating.
COMPARING LITRE COSTS :
Often buyers tend to select a coating strictly on a cost per liter basis without considering the volume solids of the paint. The user of a coating should be interested in the cost of finishing a given unit area and not the price per liter.
In the long run the coating user receives value only from that portion of the liter that remains as dried coating film after the volatile solvent or thinner has been released. Volume solids are the key factor in determining coating economies and not weight solids.
THEORETICAL SPREADING RATE
The theoretical spreading rate is a calculation of the amount of coating on average applied to a surface, assuming no losses or penetration into the substrate. It can be calculated as follows:
Theoretical Spreading Rate (m2/L) = Volume Solids (%) x 10 / Dry Film Thickness (In microns)
Example (i): A Paint has a volume solids of 55% and needs to be applied at a dry film thickness of 75 microns. What is the theoretical spreading rate?
Theoretical Spreading Rate (m2/L) = 55 x 10/ 75 = 7.33 m2 L
Example (ii): If 10% thinner was required to thin the coating to application viscosity and a dry film thickness of 75 microns is still required. The calculation would be as follows:
Theoretical Spreading Rate (m2/L) =55 x 10 / 75 x (100%) / ( 100% +10%) = 6.67 m2 L
PRACTICAL SPREADING RATE
Except under closely controlled conditions, Theoretical Spreading Rates are hardly ever achieved, therefore in estimating coating requirements and costs, allowance must be made for losses which occur during application due to such factors as surface roughness, application method and application conditions. An empirical relationship which may be used to calculate Practical Spreading Rate as follows:
Practical Spreading Rate = Theoretical Spreading Rate X Coverage Efficiency The BELOW (table) below shows the approximate coverage efficiencies expected for various surfaces and application conditions.
