How to use

• Glass without black ceramic must be cleaned with isopropanol and then primed with Sappolo S8906 Primer. Sappolo S8906 primer is also advised where there is excess rust.
• Apply with a manual or air/battery caulking gun.
• Uncured adhesive can be removed with isopropanol; cured adhesive can only be removed mechanically.

Typical applications

• Glass bonding: car, coach, caravan, marine, train and aerospace
• Structural elastic bonding of metals, coated surfaces and many plastics (not PE, PP, Teflon)
• Bonding in vibrating constructions
• Backfilling and seaming between glass and body
