Isatis Polyester putty, which is formulated on the basis of unsaturated polyester resin, has a very good performance at low temperatures, and despite having high mechanical resistance, it has high softness and easy sanding, even after a few days of application. Its advanced formula ensures excellent adhesion to metal and galvanized surfaces. The putty is suitable for both wet and dry sanding, and thanks to its benzoyl peroxide hardening agent, it can harden even at low temperatures. It leaves a non-sticky surface and does not cause any shrinkage during the curing process.
