Overview
Bostik 4145 is a nitrile-rubber adhesive supplied as a single-component, solvent-borne system. It dries rapidly to form a resilient, elastic film that tolerates oils and plasticizers and resists degradation from water and detergents. Its high viscosity supports controlled application and gap-filling where required. No additional curative is needed, simplifying use and inventory. The product includes flame-retardant properties suitable for applications where fire performance is a consideration.
