Description
Rapid Cure Epoxy Putty
Sylmasta AB Rapid 5 Minute Epoxy Putty is a high-strength, ceramic-filled two-part repair compound designed for fast repairs, refurbishment and maintenance applications. With a working time of just 5 minutes, it is ideal for situations where speed is critical whilst still providing exceptional strength, durability and chemical resistance.
Unlike standard epoxy putties, AB Rapid is supplied in separate resin and hardener components, allowing larger quantities to be mixed for major repairs. Once cured, it forms a hard-wearing repair that can be drilled, tapped, machined, sanded, filed or painted, making it suitable for industrial, commercial and maintenance applications.
Suitable for both indoor and outdoor use, AB Rapid bonds to metal, wood, concrete, brick, masonry, ceramics and most plastics. It is widely used for pipe repairs, structural rebuilding, gap filling, corrosion protection and surface restoration.
