G-2305 Polyvinyl Acetate Adhesive System

G-2305 crosslinkable polyvinyl acetate adhesive system is used in applications such as veneering, edge and face gluing, finger jointing and in the manufacture of architectural doors. It can be cold pressed, hot pressed or radio frequency cured.

G-2305 must be mixed with a catalyst prior to use. 5% by weight of catalyst is the recommended level for most applications. Stir adhesive during catalyst addition and continue agitation for at least 5 minutes to ensure a uniform mixture Avoid contact of catalysts or mixed adhesive with eyes or skin. Wash off immediately with water.

The recommended pressure for flat laminations glue line ranges 30-100 PSI. Higher pressures are required for hardwoods (175-200 PSI) and soft woods (100-150 PSI) in edge-gluing or face-gluing. For hot pressing the press schedule will vary with operating conditions.

G-2305 is stable for 3 months from date of manufacture at 21°C.Maximum stability is obtained if stored between 5-15°C. The viscosity of G-2305 will increase with time in storage, but as long as the material can be stirred to a smooth consistency it is satisfactory for use. Rotate adhesive stock. Protect from freezing. Do not mix with other adhesives.
