Adhesives

Adhesive performance is governed by a balance most coatings never face: the polymer must wet and adhere to two often-dissimilar substrates while developing internal cohesion that resists peel, shear, and (depending on application) elevated temperature or chemical exposure. Choice of base polymer chemistry, tackifier balance, and crosslinker package determines whether you get a removable label adhesive or a structural bond rated for 80 °C continuous service.

Coatingsink supplies adhesive raw materials across the full taxonomy: acrylic emulsions and dispersions for PSAs and water-based bonding, SIS and SBS thermoplastic elastomers for hot-melt PSAs, polyurethane prepolymers and hardeners for laminating and structural bonding, epoxy systems for structural metal bonding, polyamide and EVA for hot-melt packaging, and the rosin esters, hydrocarbon resins, plasticizers, and crosslinkers that complete each formulation.
