Why do hot-pressed veneers always have problems such as bubbling, cracking and warping at the edges? This glue from Fushen can help you solve the problem
Cracking, bubbling and warping at the edges of hot-pressed veneer are these major problems that surely trouble many manufacturers engaged in hot-pressed veneer processing. The equipment has been debugged in various ways and has been pressed several times but still doesn't work. The cause can't be found. How to solve this problem!
If the problem still cannot be solved after equipment debugging, it is very likely that the selected glue is not suitable. Non-environmentally friendly urea-formaldehyde glue and ordinary white latex glue are difficult to solve the above-mentioned problems when the quality of hot-pressed wood veneer is required to be higher.
Fushen GW-6528A hot-press adhesive for bonding may be a more suitable glue at present. It not only meets environmental protection requirements but also can greatly solve the problems of cracking, bubbling and warping at the edges.
First, the adaptability of the process breaks through traditional limitations
1. Low-temperature rapid pressure to prevent cracking
Unlike traditional urea-formaldehyde adhesives that require curing at temperatures above 100℃, GW-6528A only needs a temperature of 80-90℃ and 2-3 minutes of hot pressing to complete the curing process. This mild hot-pressing condition can significantly slow down the rate of moisture loss from wood veneer, preventing the wood fibers from cracking due to sudden shrinkage. It is particularly suitable for temperature-sensitive materials such as smoked wood veneer and dyed wood veneer, as well as the high-difficulty bonding of thick and hard wood veneer.
2. High thermal strength and non-permeable property
The formed adhesive film after curing is strong and flexible, with a thermal strength far exceeding that of modified white latex. It can resist the stress changes of wood and fundamentally solve the problems of warping and bubbling. Meanwhile, the high-solid content colloid design has excellent sealing performance, completely avoiding glue penetration and contamination, ensuring a clean and beautiful surface of the wood veneer. It is especially suitable for the strict texture requirements of high-end furniture.
Second, it takes into account both environmental protection performance and operational convenience
Zero-formaldehyde single-component design
The product contains no free formaldehyde, meets the European E0 environmental protection standard, and has passed international certifications such as SGS testing. As a one-component glue, it does not require additional glue mixing. It can be used directly after opening the can, reducing the complexity of the production process and human errors.
2. Compatible with water-based paint and secondary processing
It reaches the D3 waterproof grade and can be directly adapted to water-based paint processes without worrying about the compatibility issues between the adhesive layer and the coating. In addition, even if the glue is completely dry, it can still regain its bonding activity after heating, supporting the secondary hot pressing of extended and enlarged plates, providing convenience for complex processing.
Iii. Additional functions enhance comprehensive value
Anti-bluing and long-term stability
It can neutralize tannic acid in red oak, white oak and cherry wood veneer, significantly reduce the probability of blue color change of wood veneer in high-temperature and high-humidity environments, and extend the service life of products. Meanwhile, the film has excellent water resistance and anti-aging performance, making it suitable for damp environments or long-term usage scenarios.
2. Compatibility and application flexibility
In addition to wood veneer bonding, it can also be used for edge banding of materials such as PVC and ABS, as well as cold-pressing bonding of special substrates like carbon fiber plates. Its operation process is simple. Both manual gluing and machine gluing can be used, which is suitable for production needs of different scales.
Iv. Brand Technology Accumulation and Market Validation
As a "Chinese expert in wood veneer adhesives", Fushen has been deeply engaged in the field of woodworking adhesives for many years, and the performance of its products has surpassed international standards. The development of GW-6528A is based on a deep understanding of the pain points in the industry. Its reliability has been verified through extensive practice and has been chosen as the preferred solution by many furniture factories and high-end customization enterprises. It has performed particularly well in addressing issues such as easy cracking, glue penetration, and non-compliance with environmental protection standards of traditional adhesives.
Through technological innovation, Fushen hot-press veneer Adhesive has comprehensively broken through the limitations of traditional adhesives in terms of environmental protection, performance, and process compatibility, becoming an industry benchmark product that combines quality and efficiency. It is particularly suitable for fields with strict requirements for veneer quality, such as high-end furniture manufacturing and custom home furnishings.
