2. Uses of urea-formaldehyde resins 
The preparation process of urea-formaldehyde resin is relatively simple, and the main raw materials are urea and formaldehyde. Through the polycondensation reaction, urea and formaldehyde can generate a low molecular weight primary product solution, and then after vacuum drying, the solid form of urea-formaldehyde resin can be obtained. So its use is very wide, mainly reflected in the following aspects:
(1) Wooden furniture and building decoration field
Urea-formaldehyde resin can be used as adhesive, widely used in plywood, particle board, density board and other wood products. Its excellent strength, water resistance and weather resistance can enhance the quality and durability of wooden products.
(2) Coating and Painting Field
Urea-formaldehyde resin can be used as a base material for functional coatings and used to prepare high-performance coatings and painting materials. These materials have excellent chemical resistance, weather resistance and high temperature resistance, and are widely used in the automobile industry, shipbuilding, construction and other fields.
(3) Polymer materials field
Urea-formaldehyde resin can be used as crosslinking agent and plasticizer of polymers for the preparation of various polymer materials. For example, urea-formaldehyde resin can be blended with many synthetic resins, rubber and other materials to improve the strength, hardness and heat resistance of the material.
(4) Textile printing and dyeing field
Urea-formaldehyde resin can be used as textile anti-wrinkle finishing agent, heat-resistant resin finishing agent, etc., used to enhance the performance of textiles. Urea-formaldehyde resin has excellent durability and softness to the fiber, and can improve the wrinkle-resistant and fade-resistant properties of textiles.
(5) Daily life products
Urea-formaldehyde resin can also be used in the manufacture of tableware, bottle caps and other daily necessities and mechanical parts, as well as used as an adhesive.
In summary, urea-formaldehyde resin is simple to prepare and widely used, providing convenience for people's production and life.
