Does the wood veneer turn blue, seep through the glue or crack? Hundreds of thousands of losses! How to save it?
Not long after the wood veneer is pasted, it turns from blue to black. This is a headache for many wood product factories and may even cause products worth hundreds of thousands or even millions of yuan to fail. In fact, the bluing of wood veneer is mostly due to the tannic acid contained in the wood itself. Woods like red oak, white oak and cherry are rich in tannic acid and are prone to bluing in high-humidity environments or when contaminated by iron.
In response to this issue, Fushen GW-6528A adhesive has provided an efficient solution. This water-based one-component polyvinyl acetate adhesive is specially designed for hot-pressing veneer, manual veneer and extended and enlarged board bonding. Its core advantage directly addresses the pain point of blue color change: it can effectively neutralize tannic acid in wood, reducing the occurrence of blue color change from the source.
Meanwhile, GW-6528A has high thermal strength and is not prone to cracking, bubbling, warping or adhesive penetration during hot pressing. It also features an extremely strong waterproof performance, with a waterproof rating of D3. It can be directly applied with water-based paint, perfectly adapting to production scenarios where environmental protection requirements are increasingly strict. For the process of secondary hot pressing of the extended and enlarged board veneer, its excellent restorability can prevent the wood veneer from bubbling, and it has strong adhesion, can achieve seamless splicing, and does not allow the glue to seep through. The operation is simple and efficient.
The application case of a high-end furniture panel factory in Guangzhou further confirms its effect. This factory once used glue from a well-known German brand, but it faced problems such as the glue drying quickly, the need to add water in summer, and the cracking of the seams. After switching to GW-6528A, not only has the product quality been stabilized and the risk of blue mutation been completely resolved, but also subsequent customer complaints have been significantly reduced, providing a dual guarantee for production costs and product quality.
