Crystic® Polyester Resin 921
Crystic® 921 is an un-accelerated, orthophthalic unsaturated polyester resin with a low viscosity to accept the maximum level of filler particles. It has been developed specifically for polymer concrete. A lower viscosity, thixotropic version is available, Crystic® 921PALV. This is suitable for pigmented castings filled to a low level, or not at all.
