Description
1. Features and Uses:
Stone resin - Suitable for the production of quartz stone products;
Product features: good operability and post-processing performance. It is an o-phthalic unsaturated polyester resin with high viscosity and medium reactivity. After the material is processed, it has good surface flatness, high hardness and water resistance.

3. Suggestions for use:
The resin is a non-pre-promoting resin, and the dosage of curing agent is recommended to be no less than 1.0% of the resin. Due to the differences in the characteristics of processing processes and processed products, as well as the drift characteristics of the resin's inherent gelation time, it is necessary for users to test whether to add accelerators before use.
4. Note:
1) This product will solidify due to self-aggregation when heated. Store in a cool and ventilated place, avoid direct sunlight exposure, and avoid contact with oxidants. The shelf life is 3 months at 25ºC. The shelf life will be shortened when the storage temperature is increased or the sunlight is direct.
2) Because there are many factors in the processing process that affect the performance of resin, it is necessary for users to conduct their own tests before use. And the company reserves the right to modify the above technical data when necessary.
