Product Description

DESCRIPTION
Surtek 3356 is a one component, moisture-curable solvent free polyurethane adhesive sealant. It is non-sag, fast cure, of high bonding strength with primer. And it has good vibration and weather resistance. The product is manufactured in accordance with ISO9001/ISO14001/TS16949.

ADVANTAGES
1, Bonds and seals at the same time.
2, Short tack free and curing time.
3, Very high thixotropy for good gap-filling properties.
4, Very good Adhesion to a wide range of substrates.
5, Non-staining curing process. Solvent free, no odor.
6, Non-corrosive.No sagging
7, Inital load bearing capacity.
8, Overpaintabiliity for most coatings.
9, Increases torsional stiffness of final assembly.
10, Shock/Impact resistant.
11, Vibration and sound damping properties.

USES
Surtek 3356 is used for windshield bonding, bus body bonding, and other high-strength request bonding and gap filling.

PROCESS
Cleaning:
Clean surface with a strong jet of compressed air, sandblast, or solvent to ensure the surface being clean, dry, free of oil, grease, and of sound quality.

APPLICATION
Cut tip to desired shape and size. A triangular shaped notch will provide the desired bead shape and height. Puncture airtight seal. Install with hand or power operated gun and extrude the sealant. A height of 1/2 to 9/16 inch and a 1/4 -5/16 inch base is suggested. Put the glass in place within 15 minutes.

Drum: 200L drum

STORAGE AND SHELF LIFE
When stored at the recommended conditions in original, unopened containers, this product has a shelf life of 9 months (cartridge), 6 months (sausage and drum).
The shelf life of polyurethane sealant is related to the temperature and humidity of the environment. The recommended storage temperature is 5-25° C, humidity is <50% RH. It is strictly prohibited that the transportation or storage temperature is over 30° C or the humidity is over 80% RH. And high-temperature container transportation is prohibited as well. In the long-time high temperature and high humidity storage environment, the product is easy to get viscous, extrusion will be deteriorated and shelf life will be shortened.
