What is urea-formaldehyde resin powder?

1. Introduction of urea-formaldehyde resin powder (UF) It is a polycondensation of urea and formaldehyde under the action of a catalyst to form a urea-formaldehyde resin, and then under the action of a curing agent or an auxiliary agent, an infusible and insoluble resin adhesive โ€“ urea-formaldehyde glue is formed. Urea-formaldehyde resin can be processed into urea-formaldehyde compression powder by mixing with fillers, pigments, curing agents and plasticizers. In 1844, B โ€ข Tollens was first synthesized. In 1929, LG developed a urea-formaldehyde resin apomer that is cured at room temperature for cementing wood, and then urea-formaldehyde resin developed rapidly as an adhesive for plywood and particleboard production. Second, the advantages of urea-formaldehyde resin powder (UF) 1: Abundant raw materials and low prices 2: Good adhesiveness, weak acid and weak alkali resistance 3: Good insulation performance, excellent wear resistance, can be cured quickly at room temperature or heated to above 100 ยฐC 4: Good process performance, easy to use, poor heat resistance and aging resistance 3. Application of urea-formaldehyde resin powder (UF) Urea-formaldehyde resin adhesive โ€“ the most widely used type of glue in the wood processing industry, widely used in the bonding of wood, plywood, laminate, bamboo and wood products, such as floors, furniture, packaging boxes, textile equipment, wooden shells of household appliances, etc. .
