What is Resin Glue – Different Types and Their Applications

Resin Glue

Resin is a sticky natural or synthetic compound that is commonly dissolved in alcohol but not soluble in water. Natural resin is derived from plants, with the sap of the pine tree serving as the most notable example. The gorgeous amber stone is formed as a result of the hardening of the resin produced by the plant. 

Natural resins have been used by humans for thousands of years. Nowadays, resins have been categorized into distinct categories based on their chemical composition and purpose. Resin has wide applications across various industries. It is commonly used in the fiberboard industry, which is divided into several types depending on the density of raw materials used for production and processes in production. Each type of glue has different properties depending on the raw materials in production.

Different types of synthetic resin adhesives

Amino resins are synthetic adhesives that are divided into three basic categories: urea-formaldehyde (UF), melamine–urea-formaldehyde (MUF), and melamine-formaldehyde (MF).

Melamine-Urea Formaldehyde (MUF) resins

Melamine-fortified UF (MUF) resins are UF resins on which less than 5 percent of melamine has been added. The widespread use of these resins in wood-based goods is linked to their many benefits: Low cost, simplicity of use, durability, resilience to wear and abrasion, and resistance to heat.

MUF resin is the product of urea, melamine, and formaldehyde polycondensing. It is an inflammable and explosion-proof water suspension. The final product includes between 1% and 24% melamine. MUF resins are primarily used in the manufacturing of OSB, plywood, and other types of boards that require enhanced mechanical and waterproof qualities. MUF resins are widely used for the gluing and surface coating of wood-based consumer products in interior design. Tables and lawn chairs are examples of semi-exterior and interior wood applications.

Urea-formaldehyde (UF)

UF resin is one of the most significant formaldehyde resin adhesives. It is a polymeric condensation result of formaldehyde and urea. It is widely used in the production of wood-based composite panels, including plywood, particleboard, and fiberboard. 

UF is suitable for woodworking at home and building work such as cupboards, tables, beds, etc. Particleboard and plywood are all made with urea-formaldehyde adhesives, which are commonly used in the wood industry for merging wood to create usable shapes such as interior-grade plywood and particleboard.

Melamine-formaldehyde (MF)

Melamine-formaldehyde (MF) resin is processed and utilized similarly to urea-formaldehyde resin; however, melamine resins are more moisture-resistant, tougher, and stronger. MF is suitable for paper production applications, such as covering the paper surface. Paper impregnated with and coated with thermosetting resins is often used as a decorative and protective laminate. It is possible to create paper laminates in a paper treater by impregnating décor paper with either MF and UF resin, which is then dried and cured. The resin is then allowed to set, and the paper is then covered with a protective coating of MF resin to further preserve it.


Wood products such as particleboard are a type of fiberboard made from wood wool. The glue will be used during production to keep the wood wool together. For the furniture industry, the particleboard is made from wood shavings, wood wool, and timbering residue. The UF resin is also one glue that is used in the production process. These types of wood have a low apparent density and strength compared to other woods. Moreover, they are heat-resistant and good sound insulators, while they may also be utilized as ceiling boards or partition boards after being finished with a suitable material.

MDF (Medium Density Fiberboard) is a type of fiberboard manufactured from wood fibers and used for various applications. They are also known as dry process fiberboards. These engineered wood-based panel materials are created by gluing together wood fibers with a synthetic resin glue in a controlled environment. Resin glue is used to hold fibers together until they are homogenous, and it is utilized in the flooring, construction, and furniture manufacturing industries.

Plywood (PW) is a form of fiberboard manufactured from thin sheets of wood and primarily used in the construction industry. Plywood is made out of thin veneer sheets that are bonded together in a hot press in a direction that is perpendicular to the adjacent layer of wood. Plywood is made by gluing together planks of wood in layers, and it is used in building drawings, performance stage flooring, beach construction, furniture production, and room partition walls, among other things.

Production of Oriented Strand Board (OBS) is a thin and long piece of wood that is placed interspersed across multiple perpendicular layers by using a special glue and resin as a mixture through a compression process with Hot and high pressure until the same sheet. Sub-roof, wall partition, subfloor, furniture, booth/decoration, and construction/woodwork are commonly used, including packaging and the production of impregnation paper.


Urea-formaldehyde (UF), melamine–urea-formaldehyde (MUF), and melamine-formaldehyde (MF) are mainly used in by businesses manufacturing products out of wood. Melamine-fortified UF (MUF) resin adhesives are commonly used to bond wood to create usable forms like interior-grade plywood and particle board with several applications. As a leading manufacturer, Global Advance Industry can produce adhesives according to the Formaldehyde Emission Standard, which is classified as E2 E1 E0 Super E0.
