BOSTIK L7132K
Harmonization Code : 8529.90 | Parts solely or principally used for TV, radio, and transmission
Main features
- Two-Part High-Green-Strength Laminating
- Heat- and Creep-Resistant Bonding
- BMS 5-127G Aerospace Qualification
Product Description
Bostik L7132K is a two-part solvent-based thermoset adhesive kit consisting of L7132R adhesive and Boscodur® 24T crosslinker. It is specifically formulated for vacuum and pressure bonding of PVC films to wood, fiberboard, and other porous substrates. The system provides excellent green strength for immediate edge trimming after vacuum forming and develops tough, heat- and creep-resistant bonds with excellent adhesion to vinyl, particle board, polyolefin foams, plastics, and other laminating materials. The product meets BMS 5-127G Type III Class 2 & 3 product specification requirements for aerospace applications. :contentReference[oaicite:0]{index=0}
