Due to the complex use environment, there are certain requirements for the dustproof, waterproof, solvent resistance and other properties of the glue. PUR hot melt adhesive protects circuit printing plates used in extreme environments from moisture, moisture and other adverse conditions, and can be used in any environment and increase mechanical strength, while protecting refined lead from heating conditions.
Automotive headlamp sealing PUR hot melt adhesive is a kind of moisture reaction curing glue, which will cure when it encounters moisture in the air. In the sealing process of automotive headlights, PUR hot melt adhesive machine is often used for sealing, mainly for bonding, sealing and waterproof.
Glue can not be repeatedly heated, once unsealed, must be used within 48h, heating time should not exceed 48h;
The operating temperature can not be set too high, should be less than 140℃;
