China Factory Direct Suppliers of Two-Component Plywood Glue for Strong Bonding and Waterproofing
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).
Frequently Asked Questions
What is the composition and appearance of plywood glue?
The main agent of plywood glue is a specially made polyvinyl acetate emulsion, which is a milky white viscous liquid. The curing agent is generally isocyanate, which appears light brown in color.
What type of woods is this plywood glue compatible with?
It is highly suitable for bonding plywood made of ebony, cherry, red oak, white oak, yellow rose, black walnut, and other wood varieties.
Which quality and environmental standards does this glue comply with?
This 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 ideal environment and wood conditions for application?
The environment and wood temperature should be maintained between 6-35°C, and the wood moisture content should be kept within the range of 8-12% for optimal bonding performance.
What is the correct mixing ratio for softwoods and hardwoods?
The standard weight ratio of main agent to curing agent is 100:15. Specifically, the ratio is 100:10 for softwood and 100:15 for hardwood.
What happens if the pressure applied is insufficient during bonding?
Insufficient or uneven pressurization pressure (which should be 6-10kg/cm² for softwood and 10-15kg/cm² for hardwood) will lead to weak bonding joints and potential structural failure.
