TC-89 Polyurethane Primer

This primer was developed to apply against cured urethane substrates for achieving good adhesion when applying another urethane product for painting or bonding applications.  This product works great with BJB's flexible urethane coatings over foam and elastomer products.  TC-89 has also proved to be a good adhesion promoter when casting polyurethanes against dissimilar substrates such as other plastics and rubbers.

Note: You do NOT need to purchase additional thinner with this kit.  Both A&B components are included.
