Factory Direct Two-Component Plywood Glue from China Suppliers | High-Quality Adhesive for Wood Panels
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 6°C).
Frequently Asked Questions
What are the main components and colors of two-component plywood glue?
The main agent is a specially made polyvinyl acetate emulsion, which is a milky white viscous liquid. The curing agent is generally isocyanate, which has a light brown color.
What types of wood are suitable for this plywood glue?
It is suitable for the plywood bonding of various woods, including ebony, cherry, red oak, white oak, yellow rose, black walnut, and other similar wood species.
What international industry standards does the product meet?
The glue complies with the GB18583-2008 standard. It offers excellent bonding strength, water resistance, weather resistance, and solvent resistance, meeting both the European D4 standard and the Japanese JAS standard.
What is the correct ratio for mixing the curing agent?
The standard weight ratio is 100:15 (main agent to curing agent) for hardwood, and 100:10 for softwood applications. Insufficient curing agent ratio can lead to poor bonding performance.
What are the environmental and wood requirements for application?
The operating environment, wood, and adhesive temperature should be kept between 6-35°C (above 6°C is highly recommended). The wood moisture content must be between 8-12%, and the moisture content difference between adjacent boards should be less than 1%.
