We are the resin manufacturer you need!
Structures:Isophthalic Resin
Processes:Filament Winding、Hand lay-up Resin
Application:Suitable for products that come into contact with water, especially seawater. Has high water and chlorine resistance.
ZC-4949 resin is an unsaturated polyester resin with isophthalic acid, maleic anhydride, and standard diols as the main raw materials. It has been dissolved in styrene crosslinking monomers and has moderate viscosity and high reactivity.
ZC-4949 resin has high mechanical strength, good toughness, and low sensitivity to product fracture, thus having a high fatigue life. Especially suitable for products that come into contact with water, especially seawater. Has high water and chlorine resistance. The main molding processes include winding, extrusion, casting grids, and hand pasting. Can be used for fiberglass products such as seawater transportation pipelines, seawater aquaculture, and seawater purification. Compliant with the JC/T1092-2008 standard for mechanically formed winding resin and the GB/T21238-2007 standard for fiberglass sand filled pipes, it can be used for continuous winding processes.
