2. DESCRIPTION:

Renz 40 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-40 is manufactured in accordance with the ISO/TS 16949:2002.

3. USES:

Suitable for car body structural bonding and sealing.

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.

5. PACKAGING:

* 310ml cartridge, 20 pcs/carton

* 600ml/400ml sausage, 20 pcs/carton

6. APPLICATION:

Minimum application temperature: 5°C.

RENZ 40 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 40 in a continuous bead using enough pressure to properly apply the sealant.

7. ADVANTAGES:

* One-component formulation, excellent smooth appearance.

* Modest Hardness and high tensile strength after curing .-

* Flexible, durable and excellent extrudability.

* No sagging, no pollution and corrosion to base material and environment.

* Excellent sealing and adhesion performance, excellent water and aging resistance.

* Can be painted and abraded.

8. ADVICE:

* For common occasion, after cleaning out the surface with organic solvent, this product can be used directly.

* Please construct by application instructions strictly, failure of stickiness may be caused by any operation disobeying construction techniques.

* This product is innocuous after curing completely, but before set, please avoids contacting with eyes and skin. In case of eyes and skin contact, wash immediately and thoroughly with soap and water. See doctor immediately if it is serious.

9. PRIMING:
