Clear Aliphatic Urethane

Eight Hour Pot Life @ 77°  F

gemcoat.combo (large).jpgClear Aliphatic Urethane is a premium quality two-component urethane offering the maximum durability, moisture resistance and chemical resistance possible in a wood finish. Aliphatic Urethane is an excellent choice for interior cabinets, fixtures, and woodwork where the highest level of performance is needed. Gemini's Aliphatic Urethane has outstanding UV stability and non-yellowing properties make it the finest coating for exterior wood entry doors and furniture. For optimum performance Aliphatic Urethane should be applied as a self-sealing system.  Aliphatic Urethane addresses environmental and safety concerns by its low HAPs and VOC formulations. This product meets all of the pertinent government regulations regarding emissions and exceeds the performance parameters outlined by KCMA and ASTM.

Product Preparation & Application


Material Preparation:   This product is prepared at application viscosity and should require no thinning prior to use. However, if the conditions at your facility dictate that a thinner be incorporated, we recommend the use of SOL-9025, N-Butyl Acetate, at no more than 5% by volume.

Catalyzation:   Catalyze Clear Aliphatic Urethane with pre-packaged catalyst kit (4 parts A to 1 part B by volume) in a stainless steel or plastic lined container. Do not attempt to catalyze in smaller quantities than kit units. Mix or agitate thoroughly before use.

Application:   Clear Aliphatic Urethane is designed for spray application. Temperatures will affect viscosity. All products are designed to achieve the highest possible solids content at a viscosity low enough to allow proper spray atomization without the addition of costly chemical solvents. For optimum performance we recommend a coating system comprised of 2-3 coats of Clear Aliphatic Urethane at 3-4 mils wet film per coat. If a faster Sanding Schedule is required, a high quality Conversion Vinyl Sealer, such as 210-0008, may be substituted for the first coat of Urethane. Maximum dry film build for the complete coating system should not exceed 4 mils.

Do not use over lacquer stains or over paste wood filler, as these compromise adhesion.

Clean-up:   Use #500 Gem Coat Lacquer Thinner or SOL-9011 HAPs Free Lacquer Thinner to clean all equipment. Dispose of in accordance with Federal, State, and Local regulation regarding pollution.
