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

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.
