acid resistant epoxy vinyl ester resin

Trademark:TH-230
Types:PHigh temperature phenolic resin, epoxy vinyl
Application methods:Suitable for hand lay-up, winding, pultrusion, RTM and other molding fiberglass
Characteristics:Corrosion resistant epoxy vinyl ester resin with a phenolic

TH-200 series are free radical cured vinyl ester resins, which are introduction of foreign technology and put into new applications in heavy corrosion resistance area by Zhejiang Tianhe resin Co., LTD. TH-230 is a high Viscosity, nonpre-accelerate, methyl methacrylate modification, high-temperature type phenolic epoxy vinyl ester resin. Compared to TH-210 and TH-220, TH-230 can keep high strength and widely corrosion resistance, Especially under the low molecular organic solvents, sulfur, oxidizing substances or strong acid environment. It applies to a variety of glass fiber reinforced plastic molding process, widely used in equipment corrosion resistance of acid, alkali, salt, organic solvent and many other chemicals, it is a kind of ideal FRP heavy corrosion resistance resin.

Features:
Good high-temperature resistant to acid, alkali, salt, organic solvents and acidic oxidation medium corrosion, more than DERAKANE 470HT-400 level of temperature corrosion;
Hundred percent phenolic skeleton, a higher heat resistance (HDT of neat resin castings above 160 °C), long-term corrosion resistance, and good glass infiltration and operational;
Excellent high temperature strength, modulus and toughness retention.

Application:
Corrosion-resistant fiberglass and the overall glass lined steel tanks, pipelines, towers, ducts and FRP chemical equipment products;
Hot wet chlorine environments, acids, alkalis, oxidizing acid medium, an organic solvent environment;
Suitable for hand lay-up, winding, pultrusion, RTM and other fiberglass molding process.

Resin corrosion resistance:
As many corrosive media, space constraints do not provide, if necessary, please contact us to demand corrosion data table, determine how the selection, or coupon offers on-site testing.Other notes: Packing:
200kg drum and clean dry 18kg drums; safety recommendations: accelerator and curing agent to be stored separately during transport should be separated; should avoid contact with skin and eyes, resin, wear the necessary tools and protective clothing, is prohibited into the water. For details, see the product MSDS safety data sheet;
Storage and transportation:
t is recommended storage temperature should be below 25 °C, to avoid exposure to direct sunlight and other heat sources; May to the end of October between the resin should be transported by refrigerated trucks at night should also be unconditional transport to any improper storage and transportation will cause shorten the shelf life of resin; every time to open the lid and stir the air exchange may be appropriate to extend the shelf life;
