1、 Product Introduction

　　

　　

Zhengde Adhesive Steel Structure Adhesive is a two-component modified epoxy structural adhesive with A and B components, which is a cohesive reactive structural reinforcement material. Component A and component B should be stored separately and mixed evenly according to their proportions during use. They are mainly used for external steel plate reinforcement of concrete components in renovation projects, as well as for self-adhesion and mutual adhesion of various building materials in civil engineering.

　　

　　

2、 Product Features

　　

　　

1. High strength, especially high shear strength of steel steel and steel-concrete bonding;

　　

2. It has good adhesive force, strong shear force, anti-aging, medium resistance (acid, alkali, water) and impact resistance;

 

3. The characteristics of room temperature curing, small shrinkage during the hardening process, no flow during facade construction, no volatile solvents, and convenient construction.
