Carbon Fiber Fabric Wrap Epoxy Adhesive

Item# CarbonEpox 330

Specified adhesives for carbon fiber bonding reinforcement, has good wet ability, is a two-component, no poison, no stimulating smell Eco-friendly products. widely used in structural reinforcement of beams, floor slabs, bridges, piers, the seismic reinforcement of the deck and all kinds of concrete structure reinforcement project.

Range of application

This product is high performance epoxy resin fiber bonding adhesive, an be used for effectual permeable bonding between concrete, steel, ceramic, stone, wood and other substrates with carbon fiber, glass fiber, basalt fibers, aramid fibers etc. Mainly used for building reinforcement.

Features:

1, has excellent physical properties, tensile strength of more than 10 times higher than that of ordinary steel, modulus of elasticity is close to steel. Suitable for reinforcement of Steel bar concrete structure;

2, widely used in bending, shear, compression reinforcement of section unit, seismic strengthening of structures and masonry reinforcement;

3, the weight proportion is only 1/4 to steel, thickness of each layer is less than 1mm, almost no increasing the weight and size of the original structure;

4, no need with large construction equipment, no other fixed facilities, short construction period;

5, good corrosion resistance and durability;

6, compared with steel-adhered reinforcement methods, lower cost, easier for construction quality assurance.
