Working Procedure

1. Product application after the tests of compatibility and adhesion of the contacting materials.

2. During application the depth of sealant layer ranges from 6mm to 12mm. The width of sealant

layer must be equal to or more than the depth. The width/depth ratio is recommended to be

2:1.

3. Clean the surface with isopropanol or propanone, and keep it dry.

4. For better appearance, cover the outside of joint areas with masking tape before

application. Remove the masking tape after Immediately modifying.

5. Extrude and spread the sealant from the glue gun to the interfaces, and finishing before the

sealant solidifying to make good appearance.
