Bayhydur® 305 is a hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI) that is used as a hardener for aqueous two-component polyurethane systems. This product has a NCO content of 16.2 ± 0,4, a viscosity at 23°C of 6,500 ± 1,500, a hazen color value of ≤ 150, and a monomeric HDI content of < 0.15.
Bayhydur® 305 is a crosslinker for aqueous coatings. It was developed specially for trade applications where the ease of mixing the hardener by shaking or manual stirring is a key requirement. Despite pre-thinning, the coating yields transparent glossy films. The mixing ratio of mill base to hardener is usually 10:1.
