China Factory Direct Suppliers Two-Component Plywood Glue for Wood Bonding and Construction Applications
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
-
Insufficient curing agent ratio: Curing agent ratio 100:10 (softwood) : 15 (hardwood).
-
High moisture content: 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%).
-
Insufficient board precision: Uneven processing, knife marks, pollution, etc., resulting in the actual bonding surface being smaller than the required bonding surface (board precision).
-
Insufficient or uneven pressurization pressure: Recommended pressure is softwood 6-10kg/cm², hardwood 10-15kg/cm².
-
Low temperature: The environment, wood, and adhesive temperature are too low (recommended above 6°C).
Frequently Asked Questions (FAQ)
What is the composition of two-component plywood glue?
The main agent is a specially formulated, waterproof polyvinyl acetate emulsion (milky white viscous liquid). The curing agent is generally an isocyanate compound (light brown).
Which wood types are compatible with this plywood glue?
It is suitable for bonding plywood made from various woods, including ebony, cherry, red oak, white oak, yellow rose, and black walnut.
What standards does this plywood glue comply with?
The product complies with the GB18583-2008 standard. Its bonding strength, water resistance, weather resistance, and solvent resistance meet the European D4 standard and the Japanese JAS standard.
What are the temperature and moisture requirements for application?
The environment and wood temperature should be between 6-35°C. The moisture content of the wood must be kept at 8-12%, with a moisture content difference of less than 1% between adjacent boards.
What is the correct mixing ratio for the curing agent?
The standard curing agent ratio is 100:15 by weight. For specific applications, it is 100:10 for softwood and 100:15 for hardwood.
What pressure should be applied during the bonding process?
The recommended pressurization pressure is 6-10kg/cm² for softwood and 10-15kg/cm² for hardwood. Insufficient or uneven pressure can lead to bonding issues.
