Solvent-Based Adhesive Lamination Systems
topic
Solvent-based adhesive lamination applies polyurethane, neoprene, or EVA adhesives dissolved in ethyl acetate, toluene, or MEK at 20 to 40 percent solid content by gravure or knife coating, drying solvent in heated tunnel ovens before the two substrates are combined in a heated nip roll, with adhesive coat weight of 10 to 30 grams per square metre providing bond strength after drying and ambient cure of 24 to 72 hours.
Role
Provides high-strength adhesive bonding for composite laminates through solvent-based adhesive systems that offer the widest formulation latitude for specific substrate combinations and end-use requirements, with solvent-based lamination remaining in use for technical laminates requiring adhesive formulations with specific chemical resistance or flexibility properties not achievable with water-based alternatives, despite the environmental compliance costs of solvent recovery and emission control systems.
