When it comes to carbon fiber adhesive, many people may mistake it for only carbon fiber impregnated adhesive. However, in reality, carbon fiber adhesive also includes two types: carbon fiber base adhesive and carbon fiber leveling adhesive. These three types of carbon fiber adhesives are all two-component epoxy adhesives.

Carbon fiber primer adhesive: low viscosity, strong penetration ability, used to reinforce the bottom layer of the surface of components. Its function is to reinforce the damaged concrete after chiseling through penetration bonding.

Carbon fiber leveling adhesive: With good thixotropic performance, it is used for repairing and leveling surface defects in reinforced components. Its function is to level the surface defects, large damages, concave and convex surfaces, and corners of concrete, in order to better adhere carbon fiber cloth and play the role of carbon fiber cloth.

Carbon fiber impregnation adhesive: low viscosity, good wettability, and certain thixotropic properties, mainly used for reinforcing the surface of components and impregnating and pasting fiber products. Its function is to fully immerse in fiber products and effectively adhere them to the surface of components, thereby reinforcing and reinforcing the components.

Is it necessary to use carbon fiber pimer adhesive and leveling adhesive when pasting carbon fiber cloth?

It is not necessary to use primer glue and leveling glue, but to decide based on the surface condition of the substrate. If the surface of the substrate is relatively flat, it may not be necessary to use primer and leveling adhesive. In the case of carbon glue with instructions for no primer, the prerequisite is to meet the requirements for no primer in order to avoid using the primer.
