Artificial Stone Series Resin-quarts stone resin 7937
7937 is an orthophthalic unsaturated polyester resin mainly composed of phthalic anhydride, maleic anhydride and standard diol. It is soluble in cross-linking monomers such as styrene and has low viscosity and moderate reactivity.
● Features and Application:
7937 Lower viscosity, middle peak temperature, high strength and good tenacity, suitable for quarts stone curing in normal or middle temperature .

1.7937 Resin without waxy,accelerator,thixotropic agent,suitability is wide.
2.7937 Resin suitable for curing at room temperature and medium temperature,medium temperature curing is more beneficial to production control and product performance.
3.In the process of product production, after heating and curing, the temperature should be lowered steadily to room temperature to avoid sudden cooling and product deformation or cracking, especially in winter.The cutting and polishing of quartz during production should be carried out after full solidification
4.The filler should be avoided moisture absorption , high moisture content will affect the solidification of products, leading to performance degradation.
