Formulation of plastisol primer coat


Q. Hello,

I hope you can help me. I want to find a formula for a bonding "Primer" or undercoating for use with a standard Plastisol being used with an experimental dip coat process. The material being used to fix the Plastisol to is a braid material like wool.

A. Michael,

A good primer is hard to come by. It is essential to a proper bonding. Look up "stop-off lacquers" on the internet.

A. Dear sir,

A good prime coat is top priority. I use T-100, a Miccro product by Tolber. It works great for PVC.

A. You exactly follow the procedures from the plastisol vendor. Basically, abrasive blast the part, heat it, dip or spray in a "primer", reheat, dip or spray in plastisol. Remove extremely slowly from the dip and bake for the given time/temperature. Too low a time or temperature and it is not cured properly. Too long or hot and it chars or discolors and later cracks.
