Polyester tooling resin
Polyia

The resins in this group are specially designed for polyester mold production. These resins provide unique advantages for mold applications, such as low total volumetric shrinkage, easy wetting of fiber glass, thixotropic structure (non dripping from vertical surfaces) and also high mechanical resistance which molds are often exposed to.

Polipol 320 is an orthophtalic based, thixotropic, preaccelerated unsaturated polyester resin.
The resin is designed for the production of moulds. Polipol 320 can safety be used in other fields where similar properties are required mould making.
The most important spesification is that it has a low shrinkage and low internal stress so that the products made from it, has no deformation.
It can easily wet fiberglass and it will not drip down vertical surfaces because of its thixotropy. Because of it is a preaccelerated resin you will only add Mek-p before using it.
