Product introduction
Plywood glue refers to an adhesive used to splice wood products such as integrated materials. It is suitable for plywood bonding of non-structural materials and structural materials. The main agent of plywood glue is a specially made polyvinyl acetate emulsion with excellent waterproof effect, and the curing agent is generally isocyanate. The color is a milky white viscous liquid as the main agent, and the curing agent is light brown. The main agent of plywood glue can generally be used alone as a finger-joined glue.
Scope of application: plywood of ebony, cherry, red oak, white oak, yellow rose, black walnut and other woods.
Performance characteristics: in line with GB18583-2008 standard; good bonding strength, water resistance, weather resistance and solvent resistance, all indicators meet international industry standards-European D4 standard and Japanese JAS standard.
Usage requirements: environment and wood temperature 6-35°C, wood moisture content 8-12%, curing agent ratio 100:15 (weight ratio), wood precision error
Common problems of two-component plywood glue
1. Insufficient curing agent ratio, curing agent ratio 100:10 (softwood): 15 (hardwood).
2. The moisture content of the board is too high (the moisture content is 8-12%, and the difference in moisture content of adjacent wood is less than 1%)
3. The board precision is not enough, uneven processing, knife marks, pollution, etc., resulting in the actual bonding surface being smaller than the required bonding surface (board precision
4. Insufficient or uneven pressurization pressure (softwood 6-10kg/cm2, hardwood 10-15kg/cm2).
5. The environment, wood, and adhesive temperature are too low (recommended above 6C).
