- Fast-Drying One-Part Nitrile Adhesive
- Non-Staining Bonding Formulation
- Flexible Cured Adhesive
Product Description
Bostik LIQ. 4045 is a fast-drying, one-part solvent-based nitrile adhesive formulated for bonding flexible PVC to a wide variety of substrates used in plastic upholstery and industrial assembly. The high-viscosity formulation develops high initial bond strength while producing a clear, flexible, non-staining bond line with excellent green strength. LIQ. 4045 also provides resistance to solvents and plasticizer migration, making it suitable for bonding vinyl, PVC foam, fabrics, ABS, and aluminum in upholstery and interior trim applications. :contentReference[oaicite:0]{index=0}
