Product Description
CT-E1211 is a one-component, heat-curable epoxy structural adhesive. After curing, it provides excellent bonding strength, electrical insulation, and chemical resistance, with low shrinkage. The product is solvent-free and environmentally friendly, and complies with RoHS and REACH requirements.
Product Features
Moderate viscosity for easy application.
Medium-temperature curing with a fast curing speed and short curing time.
High bonding strength. It provides excellent bonding performance with metals, especially magnetic steel, galvanized steel, and stainless steel, under both room-temperature and elevated-temperature conditions.
Low storage requirements; refrigerated storage is not required.
Wide operating temperature range of -50°C to 150°C.
Applications
CT-E1211 is mainly suitable for applications in the automotive, electronics, rail transit, and other industrial fields where medium- to low-temperature curing and excellent bonding performance are required. It is particularly suitable for bonding magnetic steel, galvanized steel, and stainless steel.
Packaging
10 kg/pail. Customized packaging is also available according to customer requirements.
Storage and Transportation
Store under refrigerated conditions. The shelf life is 3–6 months.
The product is non-flammable and non-explosive and can be transported as general chemical goods. During transportation, protect the product from direct sunlight, compression, and impact to prevent leakage.
