We are the resin manufacturer you need!
Structures:Orthophthalic
Processes:Hand Lay-up Resin
Application:It has been dissolved in cross-linking monomers such as styrene and MMA, and has low viscosity and medium reactivity.
ZC-591 resin is an o-phthalic unsaturated polyester resin with phthalic anhydride, maleic anhydride and standard diols as main raw materials. It has been dissolved in cross-linking monomers such as styrene and MMA, and has low viscosity and medium reactivity.
ZC-591 resin has good strength and rigidity, excellent light transmittance, and good water and weather resistance. It is suitable for hand lay-up process to make high light transmittance fiberglass sheets.

1. ZC-591 resin contains wax, but does not contain accelerators and thixotropic additives.
2. ZC-591 resin is suitable for hand lay-up process to make light-transmitting panels with high weather resistance.
3. When selecting glass fiber, the refractive index of glass fiber and resin should be matched to ensure the light transmittance of the panel.
