It reacts with moisture in the air to form a kind of elastomer with high strength, aging, vibration, low and corrosive resistance properties. PU Sealant was widely used to join the front, back and side glass of the cars and also can keep a steady balance between the glass and the paint on the bottom. Normally we need to use a sealant guns to press out when it shaped in a line or in bead.

Suitable for automobile windshield and side glass installing.
Suitable for car body structural bonding and sealing.
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.
Minimum application temperature: 5°C.
P303R should be dispensed from either the cartridge or sausage by means of a caulking gun. Pierce the membrane at the top of the cartridge and screw on the nozzle. Cut nozzle to give the required angle and bead size. Place the cartridge in an applicator gun and squeeze the trigger. For sausages, a barrel gun is required, clip the end of the sausage and place in barrel gun. Screw end cap and nozzle on to barrel gun. Using the trigger extrude the sealant, to stop depress using the catch plate. Apply P303R in a continuous bead using enough pressure to properly apply the sealant.
