Wood Adhesive Powder is a thermosetting resin powder made by reacting urea with formaldehyde. As the powdered form of urea formaldehyde resin, it inherits the core characteristics of urea formaldehyde resin and has the advantages of easier storage, transportation, and blending due to its powdered form. The rubber powder is soluble in water before solidification, and can quickly dissolve into liquid urea glue after stirring with water, while maintaining its physical and chemical properties unchanged. The cured resin is non-toxic, colorless, and has good light resistance. It does not change color after long-term use and maintains stable color during hot forming. Colorants can also be added to prepare colored products.

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)

Wood Adhesive Powder Features:

1. Excellent curing performance

Wood Adhesive Powder can quickly cure at room temperature or when heated above 100 ℃. The curing process releases low molecular weight substances, forming a tasteless and light resistant solid. The curing speed can be adjusted by adding curing agents (such as ammonium chloride) and accelerators (such as zinc sulfate, trimethyl phosphate) to meet different process requirements.

2. Good physical properties

The cured resin has high hardness, scratch resistance, oil resistance, mold resistance, and excellent insulation performance. It is soluble in water before solidification, making it easy to mix and use. The powdered form makes transportation and storage more convenient, with adjustable solid content to meet diverse production needs.

3. Gradually improving environmental performance

Traditional urea formaldehyde resins may release formaldehyde during the curing process, but the new environmentally friendly urea formaldehyde glue powder produced from formaldehyde has significantly improved this problem and has the characteristics of being green, environmentally friendly, non-toxic, and odorless. In addition, modification techniques such as adding melamine co polymerization can further enhance water resistance and environmental performance.

4. Excellent processing performance

Wood Adhesive Powder has good process performance and is easy to use. It can be mixed with other additives (such as fillers, pigments, lubricants) to produce products that meet different needs. Its powdered form is easy to achieve mechanized and automated production, improving production efficiency.

5. Wide potential for modification

Performance optimization of urea formaldehyde rubber powder can be achieved by adding modifiers, curing agents, and other methods. For example, adding crosslinking agents such as aluminum sulfate and aluminum phosphate can improve its water resistance; Adding thermoplastic resin for blending modification can improve its aging resistance; Adjusting the synthesis process or adding formaldehyde capture agents can reduce the content of free formaldehyde.

Wood Adhesive Powder Application:

1. Wood processing industry

Wood Adhesive Powder is one of the most widely used adhesives in wood processing, widely used for bonding wood, plywood, laminated boards, bamboo and wood products, such as flooring, furniture, packaging boxes, textile equipment, and wooden shells for household appliances. Its excellent bonding strength and curing performance ensure the firmness and durability of the product.

2. Building decoration materials

Used for manufacturing building decorative panels, veneers, fiberboards, etc., endowing products with good surface smoothness and decorative effects. The light and water resistance of urea formaldehyde adhesive powder enable these building decoration materials to maintain their beauty and stable performance for a long time.

3. Manufacturing of daily necessities

Used for producing daily necessities with low water resistance and dielectric performance requirements, such as power strips, switches, machine handles, instrument housings, knobs, etc. The low cost and ease of processing of urea formaldehyde adhesive powder enable large-scale production of these daily necessities to meet market demand.

4. Mold manufacturing

Used for manufacturing entertainment products such as mahjong tiles, chess pieces, etc., utilizing their good formability and scratch resistance to produce colorful and hard textured mold products.

5. Other industrial uses

Wood Adhesive Powder can also be used to manufacture pulp, coatings, electrical components, etc. for paper and fabric. Its wide range of applications reflects the value of urea formaldehyde adhesive powder as a multifunctional material.
