What kind of glue is used for assembling the painted surface? Let's handle it with Fushen GW-6569 glue
Share
In the processing of wood products, the assembly of painted surfaces often encounters difficulties: painted wood products are prone to delamination and cracking when bonded with similar, ordinary wood products or polyester products. The GW-6569 paint surface assembly adhesive from Fushen Woodworking Glue can specifically solve such problems.
I. Core Difficulties in Assembling the Painted Surface
① Paint film barrier: The paint cures to form a dense paint film, which ordinary glue cannot penetrate and only adheres to the surface. It has weak adhesion and is prone to delamination.
② Difficulty in material compatibility: The assembly involves multiple materials such as painted wood, ordinary wood, and polyester, with significant differences in surface properties. Ordinary adhesives are difficult to be compatible, and the bonding strength is uneven.
③ Poor weather resistance: The adhesive layer of ordinary glue has weak resistance to aging, water and creep. It is prone to cracking and softening when exposed to changes in temperature and humidity, which can cause the assembled parts to loosen.

1. Key product parameters

| Project | Technical parameters | Reference standard | Core value |
| Appearance | Milky white/beige uniform viscous emulsion | GB/T 14074.1-1993 | The formula is uniform and the consistency of the adhesive distribution is good |
| The amount of adhesive cloth | 80-150 grams per square meter | - | The amount of glue is reasonable to avoid waste |
| Solid content | 38-42% | GB/T 2793-1995 | The cured adhesive layer is dense and has sufficient strength |
| Viscosity | 90000-108000CPS | GB/T 10247-1998 | It is not prone to sagging and is suitable for assembly on irregular surfaces |
| PH value | 3.0-4.0 | GB/T 14518-1993 | Weakly acidic, does not corrode the substrate |
| Shelf life | 18 months (5-35℃, away from light | GB/T 7123.2-2002 | The storage is loose, facilitating bulk purchasing |
2. Bonding conditions
The moisture content of the wood should be 6-14% to prevent the adhesive layer from foaming or losing water too quickly.
The bonding surface must meet the processing accuracy standards, be fresh and free of oil stains and dust to ensure a tight bond.
The maximum strength is reached 7 days after gluing and it needs to be left to stand for a sufficient period of time.

3. Core advantages
High bonding strength: It can achieve the "paint film destruction" effect (the paint film cracks first when subjected to force, while the adhesive layer remains intact), breaking through the limitations of the paint film.
Multi-material compatibility: Compatible with any combination and bonding of painted wood, ordinary wood, and polyester products without the need to change glue.
Strong weather resistance: The adhesive layer is heat-resistant, water-resistant, creep-resistant, and aging-resistant, adapting to changes in temperature and humidity.
Easy to operate: Single-component form, ready to use out of the box, no need for blending, lowering the operational threshold.

4. Applicable scenarios
It covers the assembly of painted wood products, the bonding of polyester products and painted wood products, and the composite assembly of multiple materials (such as the bonding of ordinary wood and painted wood), etc.
