Common epoxy resins and their performance advantages

Epoxy resin is an epoxy paint Commonly used resins in the series, but the composition is not the only one. Some also contain other resins, such as polyamide resin, epoxy resin, etc., but they are mixed to form different paints. Since epoxy resin is a necessary ingredient, let’s take a brief look at its properties and characteristics.

1.The situation is diverse. Can effectively handle different forms of requirements, such as from low viscosity to high melting point solids.

2. Strong adhesion , Convenient curing. The epoxy resin system can be cured in the temperature range of 0 to 180°C, and has low shrinkage during curing, which is beneficial to improving its adhesion.

3. The cured epoxy resin system is a Excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance. It has good mechanical properties, electrical properties and chemical stability.

Epoxy Resin

What are the commonly used epoxy paints in our daily lives? What are the characteristics of epoxy resins? What’s the difference?

The first type: Epoxy ester resin: This resin is obtained by the esterification reaction of vegetable oleic acid and bisphenol A-type epoxy resin. Advantages: good storage stability, low cost, and simple construction. It is these advantages that can be made into drying paint and self-drying paint. Disadvantages: poor weather resistance.

Second type: modifiedepoxy resin. Bromine modified epoxy resin is commonly used in coatings. The introduction of bromine can improve the flame retardancy of epoxy resin. Fire retardant coatings are commonly used, followed by silicone modified epoxy resin. Its introduction can improve the epoxy resin. Its water resistance, heat resistance, and weather resistance are mostly used in the manufacture of heat-resistant epoxy anticorrosive paints. Finally, organic titanium modified epoxy resins, whose introduction can effectively improve the overall performance of epoxy resins.

The third type: water-based epoxy resin. Commonly used are drying type and self-drying type. Drying epoxy resin is more common in electrophoretic paint, while self-drying epoxy resin is mainly emulsified epoxy resin, which is often used as a water-based epoxy resin curing agent such as water-based polyamide to prepare two-component water-emulsified coatings.

The above are the epoxy options that can be selected when producing epoxy paint Resin classification and characteristics are introduced. Only by clearly knowing their differences and performance advantages can we produce high-quality paint products and sell them well in the market.
