Product Description
Epibond® 8543 C/B Epoxy Adhesive is a two-part, fast-setting epoxy adhesive designed for rapid repair and bonding applications, including use at lower temperatures. The system features a convenient 1:1 mix ratio and paste consistency for controlled application. At 77°F (25°C), bonded assemblies may be handled in approximately 10 minutes and develop high strength within one hour. The contrasting white resin and black hardener produce a uniform gray color when fully mixed, providing visual confirmation of proper mixing. Epibond® 8543 C/B is qualified to BMS 5-123 Type 1 Class 3 and is supplied in cartridge and bulk formats for industrial bonding and repair operations.
Key features
- Fast-setting epoxy system: Bonded parts may be handled in approximately 10 minutes at 77°F (25°C), supporting rapid repair and assembly operations.
- 1:1 mix ratio: Equal-part mixing by weight or volume simplifies dispensing and preparation.
- Visual mix verification: Contrasting component colors produce a uniform gray adhesive after complete mixing.
Applications / Suitable for
- Quick repair and bonding applications
- General industrial assembly operations
- Bonding applications requiring rapid strength development
- Repair work at ambient and cooler operating temperatures
