Urea Formaldehyde Wood Glue Parameters:

Wood Adhesive Powder Instructions For Use:

1. Prepare a container, stirring tools, and 25kg of room temperature water (add the water twice).

2. Dissolving glue powder:

First pour 15kg of water into the container,

then pour 25kg of resin powder into the water and stir to dissolve.

Stir into a paste until the glue powder does not agglomerate,

then add the remaining 10kg of water and fully stir to form a glue solution.

3. The mixed glue is used after 1 hour of waiting, and the effect is the best.

4. According to the production requirements of the product process, it can be mixed with additives such as curing agent(Ammonium chloride) .

5. During use, increase or decrease the ratio of resin powder to water according to the moisture content of the board and the local climate.

6. Amount of industrial flour added: 20-25% of the glue already blended.(180A to add)

Urea Formaldehyde Wood Glue Features:

1. Excellent Bonding Performance

Density Board Urea Formaldehyde Wood Glue Powder offers exceptional bond strength, ensuring a tight connection between wood fibers. Its bond strength meets industry standards, maintaining excellent adhesion even after boiling at 80°C for 2.5 hours (Type 180) or 100°C for 3.5 hours (Type 180A). This high-strength bond makes it an excellent choice for the production of wood products such as density board, effectively preventing the loosening of wood fibers during processing and use.

2. Moderate Curing Speed

Urea Formaldehyde Wood Glue offers a moderate curing speed, adapting to varying production schedules. With the addition of a curing agent, the curing time is only 3 hours, making it suitable for fast production runs. Without a curing agent, Type 180 has a pot life of 24 hours. Type 180A also has a pot life of 24 hours with the addition of industrial flour, and can reach 48 hours without industrial flour or a curing agent. This flexible curing time setting provides wood processing companies with more flexibility and can effectively improve production efficiency.

3. Precise Hot Pressing Parameters

Urea Formaldehyde Wood Glue has clear hot pressing process parameters: a hot pressing temperature of 80-120°C, a hot pressing pressure of 8-16 kg/cm², and a hot pressing time of 1 minute per millimeter of thickness. These precise parameters ensure optimal bonding during the wood processing process while preventing damage to the wood due to excessive temperature or pressure. By strictly adhering to these parameters, the quality of wood products produced is effectively guaranteed.

4. Good Environmental Performance

Although urea-formaldehyde resin glues are traditionally associated with environmental concerns, Density Board Urea Formaldehyde Wood Glue Powder uses an optimized formula and production process to keep formaldehyde emissions within industry standards. Its production strictly adheres to environmental regulations, ensuring that the product's impact on the environment and human health during use is minimized, meeting the environmental protection requirements of the modern wood processing industry.

5. Wide Range of Applicable Wood Materials

Urea Formaldehyde Wood Glue is suitable for a wide range of wood types, especially for man-made boards such as density board (MDF). It can accommodate wood with a moisture content range of 8%-10% + ≤ 2%, ensuring stable bonding performance under varying humidity conditions. This wide applicability makes it an ideal choice for the wood processing industry, meeting diverse customer needs.

6. High Product Stability

Density Board Urea Formaldehyde Wood Glue Powder is a white powder packaged in 25kg containers with a shelf life of up to one year. During storage and transportation, the product maintains stable physical and chemical properties and is not susceptible to deterioration due to environmental factors. This stability ensures that the product maintains excellent performance even after long-term storage, reducing waste caused by deterioration.

7. Appropriate Application Weight

The application weight of Urea Formaldehyde Wood Glue varies depending on the grain and smoothness of the board, generally ranging from 150-180 grams per square meter per side. This moderate coating amount ensures sufficient bond strength while avoiding the increased costs and processing difficulties associated with over-application. By precisely controlling the coating amount, wood product production can be more efficient and economical.

8. Easy to Use

Urea Formaldehyde Wood Glue is easy to use; simply add the curing agent in the prescribed proportion. Its operation conforms to conventional processes in the wood processing industry, requiring no complex equipment or specialized skills. It can be quickly integrated into existing production processes, reducing costs and operational complexity for businesses.
