Bayhydur® BL 5335

Bayhydur® BL 5335 is a hydrophilized, blocked aliphatic polyisocyanate based on Desmodur® W, in combination with Bayhydrol® grade OH-functional polymers for the formulation of lightfast, single-component polyurethane baking coatings. This product has a non-volatile content (1g / 1h / 105°C) of 34-36, a flow time at 23°C, (4mmcup) of 10-30, a pH at 20°C of 4.4-6.0.

Bayhydur® BL 5335 is a blocked polyisocyanate and was developed for industrial use. It is used as a hardener for the formulation of lightfast one-component polyurethane baking coatings suitable for spray, dip or roller application. The product is preferably used in glass coating applications. It can be used in combination with Bayhydrol® U XP 2239 for the formulation of hydrolytically stable coatings with good glass adhesion and outstanding resistance to solvents and chemicals, in particular sodium hydroxide. Baking parameters are 30 minutes at 170°C.
