Single Part Fast Curing Polyurethane Adhesive Bonding Performance
And Durable Windshield Adhesive Sealant
Junbond® JB-16 is a silicone glass sealer that flows into hidden cracks and areas
that may be harder to reach. The sealant provides a tough,
waterproof, durable, and clear seal that will prove to be resistant
to different types of weather conditions, extreme temperatures,
vibrations and shocks, and even most chemicals.
Junbond® JB-16 Windshield Polyurethane Sealant an isocyanate-free, high modulus,non conductive, thixotropic,
single component modified polyurethane adhesive, which polymerizes
rapidly under the effect of atmospheric moisture. It has been
specially designed for bonding of fixed glass in automotive repair.
- Suitable for applying to the opening of the windscreen made of
any material, including aluminum;
- Due to its high initial hardness and exceptionally strong binding
properties, no additional fixation of the glass is required;
- Very good resistance to sagging;
- Does not "reach" for the tool;
- High speed of polymerization;
- High shear strength and high shear modulus. Good elasticity even
after long-term use;
- Very low electrical conductivity;
- Good adhesion to the residual materials of the old adhesive
- High resistance to UV radiation;
- Excellent adhesion to glass, glass with a ceramic coating and to
It allows a drive away time of 6 hours in vehicles with or without

Clean before operation
Clean and dry all surfaces by removing foreign matter and
contaminants such as oil dust, grease,
frost, water, dirt, old sealants and any protective coating. Dust
and loose particles should be cleaned.

Tool:Manual or pneumatic plunger caulking gun
1.Clip the end of the sausage and place in barrel gun
2.Screw end cap and nozzle on to barrel gun
3.Using the trigger extrude the sealant with equal strength
1.Obtain a new windshield.
2.Remove the plastic surround side and top mouldings correctly.
3.Cut the urethane from the outside between the glass and the
4.Apply a windshield primer to the frit band.
5.Apply the urethane with an electric caulking gun.
6.Lift the windshield into place.
7.Push the window down around the frame to guarantee a tight bond.
8.Allow the urethane to dry.
