Product Description

ZL-N epoxy putty is a two-component, putty-like modified epoxy resin adhesive.

1. Exhibits excellent spreading and scraping performance, with no knife sticking;

2. Excellent construction performance—can be applied thinly either vertically or horizontally without running or sagging;

3. High structural strength and excellent bond strength with concrete;

4. After curing, it serves as a structural layer and can be reinforced again without needing to be chiseled away;

5. Can adhere to damp surfaces, with stronger adhesion in dry environments;

6. Contains no volatile solvents and exhibits minimal shrinkage during curing;

7. Exhibits excellent anti-aging properties and resistance to media erosion;

8. Close in color to concrete;

9. Cures at room temperature, with a relatively fast curing speed that can also be adjusted according to customer requirements;

10. The mixing ratio of components A and B is wide, making them easy to use and non-toxic.
