Room temperature curing epoxy adhesive is a kind of adhesive with a series of advantages such as time saving, labor saving, labor saving, energy saving, easy to use, etc. It is applied to all walks of life, such as: in aviation, in some large-scale or Fine-component adhesives for the machinery and electronics industry, aircraft damage, rapid repair of civil buildings, bridges, dams, repairs and reinforcements, agricultural machinery repairs, repairs and protection of cultural relics, wet surfaces and water glue, etc. Therefore, the development speed is very fast and the quantity is large, becoming an important variety of epoxy adhesive. Experts of China's Epoxy Resin Industry Association, room temperature curing epoxy adhesives are divided into two categories: ordinary epoxy adhesives and special epoxy adhesives curing at room temperature (such as fast curing adhesives, UV curing adhesives)
Features of room temperature curing epoxy adhesive:


     1. Because the indoor temperature is not cured by heating, the curing process is simple, easy to use, no vulcanization equipment is needed, energy saving and cost

     2. High adhesive strength, heat resistance, corrosion resistance, and electrical properties are usually lower than those of medium and high temperature curing agents. In particular, thermal resistance decreases rapidly with increasing temperature. Long-term use temperature generally does not exceed 80 ° C.

     3. Short cycle time at room temperature.

     4. The curing time is usually 24 hours to reach the appropriate strength, and the maximum strength is reached in 3-7 days, with the change of temperature

     5, with low cost, easy to use, high room temperature, so it has a wide range of applications and a large demand, is the most variety of epoxy adhesives

Precautions for curing epoxy adhesive at room temperature:

     1. Must be cured at room temperature (15-40 ° C)

     2.Combined with high strength, heat resistance and good use of appropriate technology

     3.General epoxy adhesives should be considered to reduce costs

     4, room temperature curing should also ensure specific performance. Structural adhesives should improve the bonding strength and durability; fast curing adhesives should further improve the reactivity and so on.
