Bringing Polyaspartic Technology to the Next Level: Low Viscous Solvent-free Floor Coatings

摘要

The chemistry of polyaspartic coatings, first introduced in the early 1990s, is today a well-established state-of-the-art technology. It is based on the reaction of an aliphatic polyisocyanate and a polyaspartic ester, which is an aliphatic diamine. Polyaspartic esters were initially used as reactive diluents in conventional two-component polyurethane solvent-borne coatings. In our days they are the main component of the co-reactant for the reaction with a polyisocynate, allowing for the formulation of low or near-zero VOC coatings. The unique and adjustable reactivity of the polyaspartic esters enables the design of fast-curing coatings tailored to the needs of the application. The fast curing feature in combination with a high film build can provide significant money-saving productivity improvements as the total number of coating layers can be reduced. In addition polyaspartic coatings technology provides low-temperature curing and excellent abrasion and corrosion resistance.
