China Factory Direct Suppliers of Two-Component Waterproof Plywood Glue for Wood 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
Suitable for plywood of various woods including:
- Ebony & Cherry
- Red Oak & White Oak
- Yellow Rose & Black Walnut

Common Problems of Two-Component Plywood Glue
1.
Insufficient curing agent ratio: Curing agent ratio should be strictly followed at 100:10 for softwood and 100:15 for hardwood.
2.
High moisture content of the board: The moisture content must be kept at 8-12%, with the difference in moisture content of adjacent wood being less than 1%.
3.
Insufficient board precision: Uneven processing, knife marks, and pollution result in the actual bonding surface being smaller than required (board precision).
4.
Insufficient or uneven pressurization pressure: Pressure should be 6-10kg/cm² for softwood and 10-15kg/cm² for hardwood.
5.
Low temperatures: The environment, wood, and adhesive temperature are too low (it is recommended to keep them above 6°C).
Frequently Asked Questions
Q1: What are the main components of this plywood glue?
The main agent is a specially formulated polyvinyl acetate emulsion that provides excellent waterproofing. The curing agent is typically isocyanate.
Q2: What is the recommended mixing ratio for the curing agent?
The general weight ratio is 100:15. Specifically, use a ratio of 100:10 for softwoods and 100:15 for hardwoods to ensure proper curing.
Q3: What wood species are compatible with this adhesive?
It is highly suitable for bonding various wood species, including ebony, cherry, red oak, white oak, yellow rose, and black walnut.
Q4: What environmental and wood conditions are required?
The environment, wood, and adhesive temperature should be maintained between 6-35°C (recommended above 6°C), and the wood moisture content should be between 8-12%.
Q5: What international industry standards does the glue meet?
The plywood glue complies with the GB18583-2008 standard, the European D4 standard, and the Japanese JAS standard for bonding strength, water, weather, and solvent resistance.
Q6: What issues can arise from improper pressure during application?
Insufficient or uneven pressure can weaken the bond. Ensure a pressure of 6-10kg/cm² for softwood and 10-15kg/cm² for hardwood is applied.
