Application
This product is an excellent curing agent, which is used to prepare epoxy adhesive and epoxy silicone resin coating, and also used in electronic industry.
Used in epoxy resin bonding, painting, casting, encapsulation, impregnation and composite materials.
Used as epoxy resin curing agent, it can be widely used in epoxy resin bonding, painting, casting, encapsulation, impregnation and composite materials, etc.
2-Ethyl-4-methylimidazole and epoxy resin has extremely good compatibility, reference dosage 2-7phr. 100g epoxy compound trial period 60-100min. curing reference conditions 60 degrees/2h+70 degrees/4h or 70 degrees/1h+150 degrees/1h. curing material deformation temperature 150 degrees-170 degrees. EMI-24 curing epoxy resin heat oxidation resistance, chemical resistance, especially the resistance of epoxy resin. EMI-24 curing agent with its dosage increases and the curing temperature increases, the deformation resistance temperature increases.
Ecological data: Slightly harmful to water, do not allow undiluted or large amounts of product to come into contact with groundwater, waterways or sewage systems, and do not discharge material into the surrounding environment without government permission.
Properties and Stability
Stable at room temperature and pressure, avoid contact with strong oxidizing agents.
Toxicity is similar to that of 2-methylimidazole, which is a skin sensitizer. Operators should wear protective gear.
Storage method
