AST Alba (AST) D45 is the waterborne polyurethane-acrylic coating for you...for today and, even more importantly, for tomorrow!

AST D45 is non-flammable, non-toxic, and is available in clear or custom coloured formats. AST D45 meets the US and UK's Environmental Protection Agency's (EPA) stringent current, as well as pending regulations for Volatile Organic Compound (VOC) emissions.

Exceptional Bonding Capabilities - No primer is needed for surfaces commonly known as "un-paintable"...like aluminium, galvanized steel, and flexible PVC. The remarkable low build feature of AST D45 allows second and third coats to be applied minutes apart. AST D45 dries in only fifteen minutes!

Ultraviolet Insensitivity - A major component of AST D45 is acrylic, the material of choice for industries which demand high protection against ultraviolet radiation. When AST D45 is applied according to manufacturer's instructions, the product is guaranteed for a period of up to 10 years against weathering, specifically: not to peel, blister, or suffer ultraviolet discolouration under normal environmental conditions. And, D45 gives you the professional finish you desire...in gloss or half matt.

Thermal Stability - Even in the extreme temperature changes in the freeze and thaw cycle of the North American climate which creates internal stresses, resulting in fatigue and breakdown over time for most coatings. Because AST D45 has a very high coefficient of linear expansion, it allows the coating to expand and contract together with the substrate.

Permeability - Another great feature - AST D45 coating system allows porous surfaces, like concrete, stone, and masonry to "breathe". AST D45 is a water barrier but not a vapour barrier. The microporous feature allows water vapours to migrate through the coating and evaporate into the atmosphere...provided that the substrate is not susceptible to water pooling. Conventional solvent-based paints act as vapour barriers. They do not allow water vapours to evaporate into the atmosphere, which forces the paint to "lift" from the surface, to peel and to blister. This feature will reduce condensation whilst protecting substrates like sandstone.

All these features translate into unprecedented savings...to the manufacturer and, to the consumer. Product descriptions, applications, and test results speak for itself!
