High Modulus Black Color Bonding Windshield Glass Polyurethane
Silicone Sealant Pu Windshield Sealant
Junbond® JB-19 is a one-part black color, High or Medium viscosity, moisture-curing
urethane adhesive. It provides high strength material designed to
bond and seals vehicle windshields and stationary glasses,
sunroofs, windows, headlamp assemblies, marine glass, and other
similar materials are easy to use and require less time to do the
job.
Polyurethane sealants provide excellent stress recovery to retain
shape after being bent or pulled, fast curing rates and even
adherence to non-primed concrete.

Properties
- 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
joint;
- High resistance to UV radiation;
- Excellent adhesion to glass, glass with a ceramic coating and to
painted surfaces;
