2. DESCRIPTION:
Pu 822 is a multifunction gun grade polyurethane based construction sealant, it is of high modulus and cures by reaction with atmospheric moisture to form a soft rubber like material with moderate elasticity and hight adhesion strength.
3. USES:
·Suitable for joints where high resistance to penetration and pressure are required.
·For joints where low movement capacity are required.
·Joints in paving,airport and bridge runway.
·Seams on water pipe(back to water).
4. ClEANING:
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.
