Some application examples TECHNICAL CHARACTERISTICS
Adesilex G19 is an extremely strong and flexible Adesilex G19 is a two-part adhesive composed of a
all-purpose adhesive especially recommended for polyurethane polymer, part A, and a special hardener,
non-absorbent or moisture-sensitive surfaces. part B.
Adesilex G19 is used for bonding: Mixing the parts carefully forms a uniformly coloured
paste that is easily applied with a notched trowel.
