Shelf Life Details The shelf life of L7132K is six months when stored at 55-80°F (15-27°C) in unopened factory sealed containers. Once the two-part system is blended, it has a pot life of eight hours., Boscodur 24T should be stored in a sealed container. Once opened it should be nitrogen purged to prevent contamination from moisture in the air. L7132R has a shelf life of at least 9 months if stored in an unopened container. Do not freeze. Shelf Life Temperature (°F) 55 to 80 Shelf Life (mon) 6, 9
Best Practices for Bostik L7132K
Adhesive can be applied via direct roll, reverse roll, gravure, or any coater common to the industry. This adhesive can also be sprayed.
Apply 100-150 g/m² (wet) adhesive to the least porous laminating surface and evaporate the solvent by standard drying techniques. Mate the secondary substrate under pressure at 110-212°F (41-100°C).
Boscodur 24T should be added to L7132R in accordance with the mixing ratio (1:16) and blended to a homogenous solution (solvent dilutions, where applicable, should be made immediately after the Boscodur 24T addition).
To cure the part, the adhesive should be held at a minimum of 190°F (88°C) for at least 4 minutes. Vacuum pressure should be held at a minimum of 15 in Hg (51 kPa), 20 in HG (68 kPa) is preferred.
Recommended clean up is with MEK/Toluene solution.
