Use of cycloaliphatic epoxy resin

1、thinner. The alicyclic epoxy compounds which can be used as the reactive diluent are epoxy-269, 206, 201 and 221 . Among them, epoxy 269 and 206 are high-boiling, low-viscosity liquids, and even in a liquid state at -60 ° C, they are excellent diluents for epoxy resins. And as the amount increases, the viscosity of the epoxy system drops significantly, but the heat distortion temperature is almost constant, which is generally not comparable to epoxy diluents.
2、absolutely winding potting material. An organic insulator made of an alicyclic epoxy compound replaces a ceramic article in an outdoor high-voltage device. Compared with ceramics, it has the advantages of light weight, small volume, good impact resistance, and can be economically made into products of different sizes and shapes.
3、Composite materials. The alicyclic epoxy compound has good heat resistance, mechanical properties and weather resistance, especially low viscosity and long pot life, and is particularly suitable for wet lamination molding and winding molding to manufacture high-strength heat-resistant composite materials. A FRP laminate made of an alicyclic epoxy compound has a compact structure, a high heat distortion temperature (above 300 ° C), excellent thermal stability and weather resistance, high impact strength and good electrical insulation.
4、Mold manufacturing. The alicyclic epoxy compound can also be used as a resin component in a plastic mold, and the obtained cured product has good heat resistance, good mechanical strength, small volume shrinkage, and high precision, and is suitable for precision molding and mold. Compared with metal molds, it has easy processing, low price, light weight and good mold.

5、adhesive. The alicyclic epoxy compound is unique in bonding applications because of its ability to form high-strength chemical bonds with unclean surfaces or even oleaginous metal surfaces, and is clearly concerned with glycidyl ether epoxy resins.

6、paint. Alicyclic epoxy compounds are also distinctive in coating applications. Coatings made from such resins are resistant to high temperatures. The alicyclic structure imparts surface resistance and leakage traces to electrical coatings, which contribute to the color retention and durability of outdoor coatings. It is obtained by mixing and crosslinking an alicyclic epoxy resin and a resin containing a base to obtain a coating having excellent properties, and can be used for a top coat, an automobile primer, and an industrial coating which requires relatively high film formability.
