High gloss, low haze and chemical/solvent resistance
Bayhydur® crosslinkers for waterborne adhesives and sealants
Waterborne polyurethane adhesives and sealants provide the high performance 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.
Bayhydur® crosslinkers are easily dispersed in the aqueous phase, even at the low shear forces often used for industrial coatings. Adhesives and sealants based on our Bayhydur® polyisocyanate crosslinkers provide:
- Good chemical resistance
- Impact resistance
- Excellent physical properties
We offer Bayhydur® BL blocked polyisocyanates for one-component (1K) formulations. Bayhydur® polyisocyanates are ideal for two-component (2K) waterborne formulations.
