2. DESCRIPTION
RENZ 20 is one component high quality multi-purpose polyurethane sealant, it cures by reaction with atmospheric moisture to form a durable and weathering resistant elastomer, RENZ 20 is manufactured in accordance with the ISO/TS 16949: 2002.
3. USES
Suitable for automobile windshield and side glass installing.
Suitable for car body structural bonding and sealing.
4. PACKAGING
310ml cartridge, 20 PCS/carton
600ml/400ml sausage, 20 PCS/carton
5. APPLICATION
Minimum application temperature: 5º C.
RENZ 20 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 RENZ 20 in a continuous bead using enough pressure to properly fill the joint.
6. 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.
7. PRIMING
Activators and/or primers is not required.
8. ADVANTAGES
