Aquolin 161 is a water dispersible polyisocyanate based on hexamethylene diisocyanate (HDI). In combination with water-borne polyurethane, polyacrylate, etc., it can be used for adhesive products toimprove the resistance to hydrolysis and heat. It also can be used for waterborne coatings. After addition of Aquolin 161, the ready-to-use mixture must be used within the pot life.
Aquolin 161 can be diluted with the solvents, such as propylene glycol methyl ether acetate (PMA), propylene glycol diacetate (PGDA), butyl acetate, etc. Only PU grade solvents (< 0.05% water) should be used and the solvents must be tested in advance by the user to determine suitability.
- Excellent resistance
- Long pot life
- Good gloss and building up
