Product Introduction
SHB-A503 carbon fiber impregnating adhesive is A, B two-component epoxy adhesive, mainly used for bonding carbon fiber cloth and other sheets, widely used in reinforcement construction. The product can be customized to produce no-base coating impregnating adhesive, so that it has a no-base coating effect, which can eliminate the use of carbon fiber substrate adhesive in construction.
Product features
· Low viscosity bisphenol A modified epoxy resin, no styrene, safe and non-toxic.
· Moderate viscosity, composite material formed with carbon fiber sheet has strong mechanical properties.
· Good infiltration and permeability, good thixotropic performance, good suspension makes the colloid flow less during vertical construction.
· Good aging resistance and medium (acid, alkali, salt) resistance.
· Room temperature curing, wide adhesive ratio, can adjust the adhesive ratio according to the temperature.
· No volatile solvent, non-toxic and so on.
