Room temperature curing epoxy adhesive is a kind of adhesive with time saving, labor saving, labor saving, energy saving and convenient use. It is applied to all walks of life, for example: in aviation, in some large or Fine component adhesives for the mechanical and electronics industries, aircraft damage, rapid repair of civil buildings, bridges, dams, repairs and reinforcements, agricultural machinery maintenance, repair and preservation of cultural relics, wet surfaces and water gels. Therefore, the development speed is very fast and the quantity is large, which becomes an important variety of epoxy adhesives.
Some experts have divided room temperature curing epoxy resin adhesive into two categories: ordinary epoxy adhesive and special epoxy adhesive curing at room temperature. (such as fast curing adhesive, UV curing adhesive)
Room Temperature Curing Epoxy Adhesive Features:
1. Since the indoor temperature is not heated and solidified, the curing process is simple, convenient to use, no need for vulcanization equipment, energy saving, and cost.
2. Higher bond strength, heat resistance, corrosion resistance, and electrical properties are generally lower than those of medium temperature and high temperature curing agents. In particular, the thermal resistance drops rapidly as the temperature increases. The long-term use temperature generally does not exceed 80 °C.
3. The period of use at room temperature is short.
4, the curing time is usually 24 hours to reach the appropriate strength, 3-7 days to reach the highest intensity, with temperature changes.
5, with low cost, easy to use, room temperature is high, so the application range is wide, the demand is large, is the most variety of epoxy adhesive.
Precautions for room temperature curing epoxy adhesive:
1. Must be cured at room temperature (15-40 ° C).
2, with high strength, heat resistance and good use of appropriate technology combination.
3, general epoxy adhesives should consider reducing costs.
4, room temperature curing should also ensure specific performance. The structural adhesive should improve the bonding strength and durability; the fast curing adhesive should further improve the reaction activity and the like.
