China Factory Supplier of Two-Component Plywood Glue for Structural and Non-Structural Bonding
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.

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 6°C).
Frequently Asked Questions (FAQ)
What wood species are compatible with this plywood glue?
This adhesive is designed for the plywood bonding of ebony, cherry, red oak, white oak, yellow rose, black walnut, and other similar wood species.
What is the recommended ratio for the curing agent?
The standard curing agent ratio is 100:15 by weight. Specifically, use a ratio of 100:10 for softwood and 100:15 for hardwood to ensure proper bonding strength.
What wood moisture levels are required for optimal bonding?
The wood moisture content must be maintained between 8% and 12%. Additionally, the difference in moisture content between adjacent wood boards should be less than 1%.
What are the temperature limits for applying this glue?
The environment, wood, and adhesive temperature should ideally be kept between 6°C and 35°C. Temperatures below 6°C can result in insufficient curing.
What is the required pressurization pressure during bonding?
For softwood, apply a pressure of 6-10 kg/cm². For hardwood, a higher pressure of 10-15 kg/cm² is required to ensure a secure bond.
Which quality standards does this plywood glue meet?
This product complies with the GB18583-2008 standard. It also meets major international industry standards, specifically the European D4 standard and the Japanese JAS standard.
