Other Products
Crack injection adhesive is a low-viscosity liquid adhesive composed of two components, A and B, modified with epoxy. It features low viscosity, low heat generation, long pot life, and a simple injection process.
I. Product Features
· Extremely low viscosity and strong permeability, capable of penetrating micro-cracks as narrow as 0.1mm.
· Excellent aging resistance and resistance to media (acids, alkalis, water).
· Outstanding toughness and impact resistance after curing.
II. Technical Parameters
