Description for Bostik BOSC132-59

A water-dispersible aliphatic polyisocyanate. When added to reactive aqueous polymeric dispersions, such as polyurethanes, polychloroprenes and acrylics, Boscodur 132 will react under ambient conditions to increase molecular weight, thereby improving the resistance of the adhesive bonds to moisture, heat, chemicals and solvents.

Best Practices for Bostik BOSC132-59

*See Terms of Use Below
1. Mixing
  
  Boscodur 132 is added directly to the aqueous adhesive dispersion under low to moderate speed mechanical agitation just prior to use. Mix for approximately 10 minutes. Avoid high speed, high shear mixing which might introduce air into the adhesive. Typical pot life is about 6 hours
  
  this varies with the type of adhesive. Do not seal containers tightly after mixing, as small amounts of carbon dioxide may be liberated. Typical levels of use are 3-7% by weight based upon the weight of the aqueous dispersion. Refer to individual Bostik product data sheets for recommended level of use.
