Polikor polisoft polyester putty is an amine preaccelerated, semiflexible, high reactive unsaturated polyester based putty which has very good adhesion, filling and sanding properties. In conjunction with benzoyl peroxide paste as hardener, it readily hardens even at low temperature conditions (down to 5 C) It gives tack-free surfaces with very low shrinkage during curing. The putty has outstanding storage stabilitly due to the built-in-amine based unsaturated polyester resin used.
