BAYHYDUR ULTRA 305

BAYHYDUR ULTRA 305 is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI). It is used as a hardener for aqueous two-component systems. BAYHYDUR ULTRA 305 was developed specially for applications where ease of manual mixing is important. Despite pre-thinning, it yields transparent glossy films with a mixing ratio of 10:1. BAYHYDUR ULTRA 305 is suitable for applications that require a hardener that can be easily mixed by hand stirring or shaking. Its single component formulation makes it convenient to use and transport. The transparent films produced after curing also make it well-suited for applications where aesthetics are important.
