Polikor super polyester putty is an amine preaccelerated, semiflexible, high reactive unsaturated polyester based putty which has very good adhesion, filling and sanding properties. The putty has excellent thixotropic structure and a butter-like workability. In conjunction with benzoyl peroxide as hardener, it readily harden even at low temperature conditions (down to 5c) it gives fine and tack-free surfaces with minimum shrinkage during-curing. The putty has outstanding storage stability due to the built-in-amine based unsaturated polyester resin and high quality fillers used.
