ergo® structural acrylic adhesives are two-component reactive adhesives that form fast-setting, high-strength bonds on glass, ceramics and metal and are used to join two substrates of the same material or different materials.
ergo® structural acrylic adhesives are designed for bonding components with different expansion coefficients that must withstand high thermal and dynamic stresses. Mechanical surface abrasion, such as sanding, grinding and sandblasting, improves the surface properties for bonding. Higher temperatures (up to about 50°C) increase the cure speed.
For so-called “no-mix” products, the resin and activator are applied separately and mix when the substrates are pressed together. Their excellent impact resistance make them suitable for bonding hinges to glass and rear view mirrors in automobiles, and for glass-on-glass applications, where aesthetic appearance is important. Adhesives come in practical double-chamber cartridges, ensuring efficient application and mixing.
- Cure time at room temperature varies between 20 seconds and 30 minutes (depending on the product)
- High initial strength after 1 to 15 minutes
- Application is easily automated
- High resistance to water, aliphatic solvents, oils, grease and diluted inorganic acids and alkalis
