What are the high quality FRP mold gelcoats

We mainly use 8200 and 191 two kinds of resin, 8200 for molds with about 25 yuan 1 kg, 191 for products 12 yuan about 1 kg, these two are basically the most commonly used FRP products now.

Summary. Dear, hello, I am glad to answer for you what gel coat is used on the surface of FRP is a good polyester gel coat is a surface protective coating of FRP products, which plays a dual role in enhancing and improving the appearance, and can get a special surface effect. GG28 is a cast steel material.

Cast steel refers to steel that is used exclusively to make steel castings. When the strength requirements of the casting are high and the cast iron cannot meet the requirements, cast steel should be used. However, the fluidity of molten steel in cast steel is not as good as that of cast iron, so the thickness of the cast structure should not be too small, and the shape should not be too complex.

Controlling the silicon content at the upper limit improves the fluidity of the molten steel. According to the variety and use, cast steel can be divided into cast steel for general engineering, cast steel for welded structure, stainless steel cast steel, and heat-resistant steel cast. GG Polyester High Gloss Gel Coat, is an air-dry polyester gel coat designed for obtaining high gloss requirements on the surface of FRP prototypes, black.

I want gelcoat for FRP surface.

Not cast steel. Phthalate type The matrix resin of phthalate gelcoat is phthalate unsaturated polyester resin, which has good weather resistance, water resistance, impact resistance and other characteristics.

Is it better to o-benzene or isobenzene?

Phthalate is good.

The performance of the gel coat is mainly determined by the matrix resin, and the gel coat is basically thickened (with silica) Most of them are also pre-promoted, according to the process, it is divided into jet process gel coat and hand lay-up process gel coat, according to the matrix resin is divided into phthalatene, isobenzene, isobenzene neopentylene glycol, vinyl, epoxy gel coat, can also be divided into product gel coat and mold gel coat, as well as air-dry gel coat, easy to polish gel coat, flame retardant gel coat and so on. The purpose of thickening is mainly to prevent the sagging of gelcoats, whether thick or thin, as long as it suits your product requirements and process operation.
