Hot Melt EVA-based adhesives are thermoplastic, have minimal surface tack and are solid at room temperatures. When heated, these adhesives liquefy, increasing their surface tack and forming a bond when cooled. They are also flexible and cohesively strong. A variety of additives are added to different grades. Waxes and tackifiers, for example, dial in temperature resistance, wettability and setting speed for a variety of end-use applications.
Bostik's Hot Melts based on Ethylene Vinyl Acetate (EVA) polymers are typically tack free and flexible at room temperature. They are supplied in pellet form, that have excellent auto feed properties, while providing superior wet-out and rapid set speed when hot applied.

Thermogrip 1935 is specifically formulated to bond to recycled board stock. It has low viscosity at 350F, which enables it to have excellent penetration and hot tack for superior adhesion to difficult substrates. Thermogrip 1935 also features a medium set speed and broad function range, making it suitable for freezer to general purpose applications.
