Unsaturated Polyester Resin ZC-157 Orthophthalic Resin

Chemical/Physical Nature

ZC-157 Orthophthalic Resin is an unsaturated polyester resin based on meta benzene, maleic anhydride, and neopentyl glycol as the main raw materials. It has been dissolved in crosslinking monomers such as styrene and has high viscosity and reactivity.

Benefits and Application

ZC-157 resin has high mechanical strength, high heat resistance, high corrosion resistance, and high wear resistance. Suitable for high-performance quartz stone, translucent stone and other products. It can also be used for hand pasting, casting grilles, winding, as well as bonding PVC and fiberglass.

Application Guidelines

1.ZC-157 resin does not contain wax, accelerators, or thixotropic additives.
2. ZC-157 resin is suitable for medium temperature curing high-performance quartz stone. Medium temperature curing is more conducive to production control and product performance assurance. Recommended medium temperature curing system: tert butyl peroxyoctanoate TBPO (content ≥ 97%), 1% resin content; Curing temperature: 80 ± 5 ° C for at least 2.5 hours. Recommended coupling agent: gamma methacryloyloxypropyltrimethoxysilane KH-570, 2% resin content.
3. During the production process of quartz stone, after heating and solidification, it should be steadily cooled to room temperature to avoid rapid cooling and prevent product deformation or cracking, especially in winter. The cutting and polishing of quartz stone during the production process should be carried out after sufficient solidification.
4. Moisture absorption of fillers should be avoided, as excessive moisture content can affect the curing of the product and lead to a decrease in performance.
