1.ZC-680 resin does not contain wax, accelerators and thixotropic additives.
2.ZC-680 resin is suitable for normal temperature and medium temperature curing. Medium temperature curing is more conducive to production control and product performance assurance. Medium temperature curing system recommended: TBPO (content ≥97%),1% resin content; Curing temperature, 80±5℃ curing not less than 2.5 hours. Coupling agent recommended: gamma-methylacryloxy propyl trimethoxy-silane KH-570, 2% resin content.
3.ZC-680 resin has wide applicability.
4.ZC-680 resin production process, after heating and curing, should be smoothly reduced to room temperature, to avoid cold, to prevent product deformation or cracking, especially in winter. The cutting and polishing of quartz stone in the production process should be carried out after sufficient post-curing.
5.ZC-680 resin should avoid the moisture absorption of the filling material, too high moisture content will affect the curing of the product, resulting in a decline in performance.
ZC-680 resin packaging: net weight 220 kg, metal drums. Please contact us for special packing requirements.
