Polyisocyanate crosslinkers enhance waterborne PU coatings : Bayhydur®

Bayhydur® polyisocyanate crosslinkers enhance waterborne PU coatings
Waterborne polyurethane coatings provide the high level of protection and appealing appearance expected from conventional solventborne systems. They also provide very low solvent content and significantly reduced solvent emissions.
Bayhydur® water-dispersible aliphatic hydrophilically modified polyisocyanate crosslinkers from Covestro are widely used for the formulation of water-based polyurethanes for:

• Adhesives
• Automotive coatings
• Can and coil coatings
• Construction/flooring coatings
• Glass coatings
• Industrial coatings
• OEM primer surfacers
• Plastic coatings
• Pigmented coatings
• Printing inks
• Wood coatings

Bayhydur® crosslinkers are easily dispersed in the aqueous phase, even at the low shear forces often used for industrial coatings. Coatings based on our Bayhydur® polyisocyanate crosslinkers  provide:

• Good  chemical resistance
• Good  impact resistance
• High gloss
• Low haze
• Excellent physical properties

We offer Bayhydur® BL blocked polyisocyanates for one-component (1K) formulations. Bayhydur® polyisocyanates are ideal for two-component (2K) waterborne formulations.
