BOSTIK L7132R
Harmonization Code : 3919.10.80 | Other self-adhesive plastic rolls not exceeding 20 cm wide.
Main features
- Two-Component High-Green-Strength Laminating
- Heat- and Creep-Resistant Bonding
- Wide Vacuum-Form Processing Window
Product Description
Bostik 7132R / Boscodur® 4 is a two-component adhesive system developed for vacuum-form bonding of PVC films to wood, fiberboard, and other porous substrates. The system combines Bostik 7132R with Boscodur® 4 crosslinker to produce strong, heat- and creep-resistant bonds while providing excellent green strength for immediate edge trimming after removal from the vacuum former. The adhesive also exhibits excellent adhesion to polyolefin foams, polyester films, laminating films, foils, sheet metal, and cellulosic materials, making it suitable for demanding transportation, furniture, and industrial laminating applications. :contentReference[oaicite:0]{index=0}
