DH-DQ001 Interlayer adhesive
Date：2018-12-18
Introduction
DH-DQ001 interlayer adhesive is A two-component polyurea material, with component A ascuring agent and component B as special composite resin and solvent. It isspecially used to promote the adhesion between the old and new polyureamaterials, so that the old and new polyurea materials form a whole, avoidingthe stratification phenomenon.
Features
★It has excellent bonding ability, and it does not fall off and crack after long-term use.
★It can be used in cold winter or hot summer.
★Fast curing and excellent performance.
★Good chemical resistance, resistant to water,acid, alkali and salt.
The main purpose
Used for bonding between old and new polyureas. Itcan also be used as a binder between epoxy putty and polyurea.
The main performance
Project | indicators |
Solid content | 30％ |
During construction period（25℃，RH=60%） | 2 hours |
Curing time（25℃，RH=60%） | surface dry ≤3 hours, the actual dry work ≤ |
Interlayer peeling strength | ≥6MPa |
Theoretical coverage | 10～15㎡/kg (film thickness: 20～30μm) |
Coating temperature | ≥5℃ |
Coating environment humidity | below 85% |
The coating method
1. The surface of polyurea layer should be clean without oil, water and impurities. If there is oil, wipe it off with acetone, xylene, etc.
2. If the substrate is polished, the binding force can be greatly improved.
3. A:B=1:4 (mass ratio). Before mixing components A and B, the weighing must be accurate.
4. The film thickness is about 25 m, Brushing too thick will affect the binding force.
5. Brush, roller coating and spraying are available.
6. The best construction time and the best binding force should be within 12 hours after drying.
