St. Louis, Missouri - Chemline Inc. has expanded its hard coatings to include more polyurea formulations, providing high-strength coatings with good low-temperature impact resistant for better performance in conditions that involve immersion and freeze-thawing, the company claims.
This expansion adds to the company's existing range of spray-applied, high performance polyurethanes, polyureas and epoxy polymers, which are used in a wide variety of industrial and construction products, such as protecting sculptured, architectural and flotation foam.
Traditional polyurethane coatings are more often used for non-critical architectural applications, the company said.
For companies that work with expanded polystyrene or polyurethane foam, in building scenery, signs or special architectural elements, "a hard polymer encapsulation is absolutely critical for the quality and durability of the end product," Chemline's 15 May statement said.
"These coatings are formulated for specialised applications. They are not cookie-cutter products that are sprayed on foam one day and pick-up truck bed liners the next day. Both the polyurethanes and the polyureas are designed with the end-users requirements in mind," commented John Henningsen, brand manager.
Polyureas also offer high impact resistance, which means they can be used in places exposed to heavy traffic without cracking or shattering. Chemthane hard coats are all 100-percent solids, with no solvents, coal tars or unnecessary fillers. They are spray-applied with high-pressure plural proportioning equipment.
The range includes standard, fast-cure PU for architectural and theming uses, and a fire retardant version, polyurea hard coatings for general foam uses; for flotation systems; and for abrasion and impact resistance, and also a fire retardant polyurea hybrid.
