| HT625 adhesive is a one-component adhesive which has been developed to bond Armaflex insulation applied on high temperature lines. Especially well matched with HT/Armaflex, it guarantees a homogeneous and safe bonding at joints and seams. | |
|
| Type of Adhesive | Contact adhesive based on Polychloroprene, free of aromatic components. |
| Appearance | Form: liquid; Color: beige |
| Special Features | The Adhesive HT 625 contains substances which etch Armaflex and hence securely join the surface to be bonded. Application on pipes and tanks up to +175° C. |
| Temperatures | Range of Application of the bonded adhesive layer | -50° C up to +150° C (+175° C)* |
Adhesive during application |
Ideal +20° C / not below 0° C |
Joint surface during application |
Ideal +20° C / not below 0° C |
Special remarks |
*At temperatures above +150° C please contact our customer service center.
In the event of temperatures below 5° C excessive amounts of condensation can form on the surface to be bonded or on the adhesive film. In this case bonding is bad or impossible. This can be tested by using absorbant paper (blotting or crepe paper).
Work should not be carried out on working plants or areas exposed to strong sunlight. |
