Tecbond 425

Tecbond 425 is a sprayable hot melt adhesive formulated for use with Tec spray applicators.

Designed as a general-purpose adhesive, Tecbond 425 has the highest initial tack of any Tecbond spray grade, ideal for applications that experience high tension upon compression. Suitable for use on wood, many plastics and heat-sensitive materials such as foams and expanded polystyrene, it’s lower viscosity allows for a better physical bond on more porous substrates.

The adhesive cools rapidly upon extrusion ensuring it doesn’t melt or burn sensitive substrates, while the increased coverage ensures there is a much stronger bond than possible with traditional bead guns.

Tecbond 425 is UL 2395 certified for bonding insulation in heating and cooling appliances. The UL Standard 2395 tests the adhesive for hot and cold temperature resistance, moisture resistance, flame spread and smoke development.
