Bending Wood Powdered UF Resin
- Product Information
Powdered UF Resin is a thermosetting resin powder synthesized through a condensation reaction using urea and formaldehyde as the main raw materials under the action of a catalyst. After fine processing and treatment, it has a low moisture content and free formaldehyde content, meeting certain environmental standards. It has a white or light yellow appearance, usually in powder form, with a particle size generally between 80-120 mesh. This resin powder is stable at room temperature, has good storage performance, and is not prone to deterioration or failure.

Powdered UF Resin Features:
1. Good adhesion performance
Powdered UF Resin has excellent adhesive strength, which can firmly bond materials such as wood, ensuring that products are not prone to cracking or peeling during use. This strong bonding force makes it an ideal adhesive choice in the wood processing industry, suitable for the production of various artificial boards.
2. Faster curing speed
Under appropriate conditions, it can quickly solidify, shorten production cycles, and improve production efficiency. This rapid curing characteristic gives it significant advantages in processes that require rapid prototyping or processing, and can meet the needs of large-scale industrial production.
3. Excellent water resistance
The cured Powdered UF Resin has good resistance to water and is less likely to cause damage to the adhesive layer or material due to water infiltration. This makes it suitable for some wooden products that need to be used in humid environments, such as outdoor furniture, building decoration materials, etc.
4. Lower free formaldehyde content
Through advanced production processes and formula optimization, the free formaldehyde content of this product has been effectively controlled at a low level, meeting environmental standards and reducing potential harm to the environment and human health.
5. Good processing performance
It can also be mixed with water or other solvents in a certain proportion according to different process requirements to form adhesive liquids of different viscosities, which are convenient for various construction methods such as spraying, brushing, and immersion, and have high flexibility in use.
Powdered UF Resin Application:
1. Production of artificial boards
Powdered UF Resin is an indispensable adhesive in the production of artificial boards such as plywood, particleboard, and medium density fiberboard. It can bond wood fragments, sawdust, and other materials together to form boards with high strength and stability, which are widely used in furniture manufacturing, building decoration, packaging materials, and other fields.
2. Wood processing and wood product manufacturing
In the process of wood processing, such as making curved wood products, wooden crafts, toys, etc., it can be used as an adhesive to ensure a strong connection between wood components, improve product quality and durability. Its excellent bonding performance and water resistance make it suitable for the manufacturing of various indoor and outdoor wooden products.
3. Furniture manufacturing
The furniture industry extensively uses Powdered UF Resin as an adhesive for boards and wood components, used in the production of various types of furniture such as tables, chairs, cabinets, and beds. It can ensure the structural stability and service life of furniture in daily use, while meeting environmental requirements, providing consumers with safe and durable furniture products.
4. Building and decoration materials
In the field of architecture and decoration, it can be used to manufacture building templates, decorative lines, door and window frames, and other materials. These materials need to have good strength, water resistance, and weather resistance, and the characteristics of Powdered UF Resin enable it to meet these requirements, providing reliable material support for construction and decoration projects.
5. Other industrial applications
In addition to the main application areas mentioned above, it can also be used to manufacture materials and products for special purposes, such as electrical insulation materials, daily necessities, packaging materials, etc. In the field of electrical engineering, its excellent insulation performance makes it suitable for making components such as insulation boards and insulation pipes; In terms of daily necessities and packaging materials, it can be used to produce products such as bottle caps and packaging boxes to meet the needs of different industries.
