TLS-402 and TLS-402E pouring adhesive are specialized adhesives suitable for fixing and pouring adhesive steel first. Creatively integrating excellent adhesive performance and convenient process performance for infusion construction in formula design. After curing at room temperature, the adhesive layer has excellent bonding and physical mechanical properties to steel plates and substrates. Even if the substrate is slightly damp, it can still be applied and cured as usual, completely replacing imported products. This product is mainly used for wet wrapped steel plate reinforcement of concrete structures, large-area steel plate grouting and pasting reinforcement of external components such as bridges, grouting repair of concrete cracks, secondary grouting of equipment anchor bolts, and construction of epoxy resin self flowing flooring. TLS-402E incorporates nanoscale fillers, which have good thixotropy and high elastic modulus, making it suitable for engineering projects with special requirements for elastic modulus.
