1. TECHNICAL DATA SHEET¢Ù:
Note£º
¢ÙAll data above ware tested under standardized condition.
¢ÚAll data listed in the chart were for the generalized item in the series; please refer to the related datasheet for special items.
¢ÛStorage condition has a direct impact to the products’ shelf life, Please refer to the instruction for special items’ storing.
2. DESCRIPTION:
PU-838 is commercial grade, one-part, non-sag, polyurethane sealant that cures by reaction with atmospheric moisture to form a durable and weathering resistant elastomer, PU-838 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. 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:
£ª310ml cartridge, 20 pcs/carton
£ª600ml/400ml sausage, 20 pcs/carton
6. APPLICATION:
Minimum application temperature: 5ºC.
PU-838 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 PU-838 in a continuous bead using enough pressure to properly apply the sealant.
7. ADVANTAGES:
£ª One-component formulation.
£ª Safe Drive Away Time in as little as two hours when used on vehicles with airbag.
£ª Modest Hardness after curing.
£ª Flexible, durable and excellent extrudability.
£ª Need no primer to glass.
£ª No sagging, no pollution and corrosion to base material and environment.
£ª Excellent sealing performance, excellent water and aging resistance.
8. ADVICE:
£ª For common occasion, after cleaning out the surface with organic solvent, this product can be used directly.
£ª Please construct by application instructions strictly, failure of stickiness may be caused by any operation disobeying construction techniques.
£ª 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:
Activators and/or primers is not required.
