Epoxy Resin AdhesiveEpoxy/silyl terminated polyether elastic adhesive
Features
- This two-part reactive mixture—an epoxy/silyl terminated polyether elastic adhesive—offers a flexible and resilient property that, in clear contrast to the hard and brittle characteristic of conventional epoxy resin adhesives, achieves a major transformation into an adhesive that will not peel off.
- For bonding that requires a high peel resistance and a high shear adhesive strength.
- For bonding in vibrating locations.
- For bonding in an environment subject to large stress variations.
- For bonding different types of materials with substantially different linear expansion coefficients.
- For bonding various types of engineering plastics.
Application
- Applications that require elastic adhesion
1. Bonding of different types of materials with substantially different linear expansion coefficients.
2. Bonding in vibrating locations and in environments subject to large stress variations.
3. Bonding in locations with a large internal strain caused by environmental changes such as thermal cycles. - Applications that require a high peel resistance and a high shear adhesive strength
- Bonding of engineering plastics including commodity plastics
1. Casting and bonding of electrical and electronic parts.
2. Bonding of glass used in precision equipment and optical equipment.
3. Bonding of building components.
4. Bonding of craft products.
