Application Of Room Temperature Curing Epoxy Adhesives In Various Industries
Room temperature curing epoxy adhesive is an adhesive with a series of advantages such as time saving, labor saving, labor saving, energy saving, and easy use. It is applied to various industries, such as: in aviation, in some large or fine component adhesive machinery and electronics industries, rapid repair of civil buildings, bridges, dams, repair and reinforcement, agricultural machinery maintenance, repair and protection of cultural relics, wet surface with water glue, etc. Therefore, the development speed is very fast and the quantity is large, becoming an important variety of epoxy adhesive.
Some experts divide room temperature curing epoxy resin adhesives into two categories: ordinary epoxy adhesives and special epoxy adhesives that cure at room temperature. (such as fast curing adhesives, UV curing adhesives)
Features of room temperature curing epoxy adhesive:
- 1. Since the indoor temperature does not need to be heated for curing, the curing process is simple and easy to use, no vulcanization equipment is required, energy saving and cost reduction.
- 2. Higher bonding strength, heat resistance, corrosion resistance, and electrical properties are usually lower than those of adhesives with medium and high temperature curing agents. In particular, thermal resistance decreases rapidly with increasing temperature. The long-term use temperature generally does not exceed 80°C.
- 3. The use cycle at room temperature is short.
- 4. The curing time is usually 24 hours to reach the appropriate strength and 3-7 days to reach the maximum strength, depending on the temperature.
- 5. It has low cost, easy use, and high room temperature, so it has a wide range of applications and large demand. It is the most popular type of epoxy adhesive.
Notes on room temperature curing epoxy adhesives:
- 1. Must be cured at room temperature (15-40°C).
- 2. It has high strength, heat resistance and good combination of proper technology.
- 3. Generally, epoxy adhesives should consider reducing costs.
- 4. Room temperature curing should also ensure specific properties. Structural adhesives should improve bonding strength and durability; fast curing adhesives should further improve reactivity, etc.
