InCat 7040


InCat 7040 is unblocked strong acid catalyst based on para-tolunene sulfonic acid which is dissovling in isoprpanol. InCat 7040 boosts the crosslinking of amino resin and polymers with hydroxly, carboxyl functionality. It will significantly accellerate curing rate and subsequently minimize energy consumption.
