Waterborne Coatings and Finishes

Benefits of Waterborne Coatings

Sherwin-Williams waterborne paint and coatings significantly improve the work environment on the production line, and radically reduce solvent emissions to the outdoor environment. In general, the waterborne range is very fast-drying. The surface is normally rather thermoplastic, which means that treated items must be handled at temperatures that are lower than is normal for curing products. Good ventilation is crucial when drying waterborne products.

Using the Sherwin-Williams waterborne wood finishes, problems with fibre raising and application difficulties can be virtually eliminated. Cross-sanding, for example, can be used to reduced fibre raising, greatly improving the result.

This means that today’s Sherwin-Williams waterborne products are suitable for most applications. For substrates that are sensitive to swelling, combining two systems can be a good solution. This also applies to dark substrates.

Interior Coatings

Sherwin-Williams waterborne ranges from Lacroma waterborne sealers and lacquers to Laqva waterborne fillers, primers and topcoats.

Lacroma Waterborne Sealers and Lacquers

Lacroma Seal: a range of fast-drying sealers with excellent sanding properties. These products can be supplied with added white pigment for a lighter finish on substrates such as pine, spruce and birch. They can be applied by spraying, rolling, dipping or by curtain coater.

Lacroma Clear: clear lacquers which can be supplied in degrees of sheen from matt to glossy. They produce high-bodied surfaces, dry fast and are easy to use in production (conforms to basic Möbelfakta standards for tabletops).

Lacroma Rustik: lacquers that protect stained and unstained surfaces, without being noticeable. They produce the same sheen as untreated wood and can be applied on top of any kind of stain and on most substrates.

Laqva Pigmented Waterborne Fillers, Primers and Topcoats

Laqva Prime: a range of waterborne primers, for use on fibreboard as well as solid wood. The products are noted for their highbuild properties.

Laqva Prime is available in several qualities, including:
•       Roller quality with excellent hiding power
•       An all-round spray or curtain primer
•       A variant for extra high-bodied surfaces

Laqva Proof: Laqva Proof is an exclusive range of primers for solid wood. It has the properties of Laqva Prime but with an incorporated mechanism which delays/protect the wood from being discolored from pine knots and tannin from tropical woods.

Laqva Fill: a range of waterborne fillers, for roller and manual application. The roller qualities are fast-drying, have high body and give minimal shrinking (very easy to sand).

Laqva Top (waterborne topcoats): fast-drying, easy to apply and are available in any degree of sheen from matt to glossy, and they are available in most colours. 

Exterior Coatings

Waterborne Paints and Lacquers for Outdoor Use

Paints and lacquers for wood that is partially or exclusively intended for outdoor use must satisfy demanding requirements. They must withstand ultra-violet radiation from the sun, rain, moisture and broad fluctuations in temperature but also discoloration from the wood. This applies to all outdoor wood, whether windows, doors, garden furniture or cladding.

Challenges for outdoor waterborne coatings
Most often, water and moisture cause the greatest problems. Since wood has a tendency to absorb water, there is constant movement in the wood substrate which makes the coatings flexibility of high importance. Wood with a high moisture content is vulnerable to rot and surface damage. All woods that are not resistant to rot should therefore be impregnated, as a first step, after which they should be coated with products designed for outdoor use – products made to withstand outdoor conditions. But for environmental reasons we suggest that you choose a durable wood quality instead of usage of VAC-impregnation.

Ensuring our outdoor coatings meet our high demands
All products within the Laqvin range are tested to outdoor exposure to make sure they fulfill our high demands. Most of them also fulfill the EN927-1 requirements. Many of our systems are also tested in tropical climate related to the L-joint standard test EN330. The test is carried out in the rainforest in Borneo/Sarawak Malaysia and will give us answers about resistance against mould, rot and about the wood quality.

Because different wood types have some tendency for discoloration and knot-yellowing, our Laqvin products have  been evaluated in accordance with prEN927-7.

Maintaining environmental compliance
The waterborne Laqvin series is an environmentally compliant alternative for the treatment of outdoor joinery. Correctly used, these products offer excellent outdoor protection. The Laqvin product range is based on different binders, mostly acrylics, alkyds and polyurethane dispersions. Available in Paints and lacquers for wood that is partially or exclusively intended for outdoor use must satisfy demanding requirements.

Types of Laqvin Outdoor Coatings

Laqvin Seal: a transparent sealer, chiefly used as a first penetrating layer to increase the woods durability against fungicide decay and to prolonge the resistance against blue stain.

Laqvin Prime: Laqvin Prime is a range of primers for outdoor joinery. They offer high body/filling properties, good penetration, high flexibility and low water permeability values.

Laqvin Proof: an exclusive range of primers for outdoor products that protects the wood from discoloration as a result of pine knots and tannin.

Laqvin Ton: a range of waterborne stains, very light-fast, for use on outdoor woodwork available in most stain tones and colours.

Laqvin Clear: this family of clear coatings comprises filmforming products (which produce high-bodied finishes) as well as products which penetrate the substrate without forming a film.

Laqvin Top: a range of pigmented topcoats for outdoor joinery, which give your pigmented products the final layer of outstanding protection and outlook.

LaqvinDry Waterbourne: cladding coating requires no investments and is available to virtually any cladding producer currently using waterborne products.

Laqvin Fast Dry Waterbourne UV: UV-cured directly after the evaporation of water.
