Product Name：Rubber Adhesive RA-65
Chemical Name：Hexamethoxymethyl Melamine (HMMM)
Property
Rubber Adhesive RA-65 is a high-performance methoxylated melamine resin used as a rubber-to-fiber adhesion promoter. It is mainly applied together with resorcinol and silica or other adhesion systems to improve the bonding strength between rubber compounds and reinforcing materials.
RA-65 provides excellent adhesion performance, heat resistance, and durability, making it suitable for tire cords, conveyor belts, hoses, and other rubber products requiring strong rubber-fiber bonding.

Features
Rubber adhesives are mainly divided into two categories: structural adhesives and non-structural adhesives. The structural type is divided into solvent glue type and adhesive film tape type. Most of them are composite systems (except polyurethane glue), which will be discussed in section VII. Non-structural rubber adhesives can be divided into two categories: solution type and emulsion type. Among them, the solution type rubber adhesive (rubber glue for short) is the main type.
Rubber glue is divided into two types: non-vulcanized and vulcanized. After the raw rubber is fully masticated and directly dissolved in organic solvents, non-vulcanized rubber adhesives, such as natural rubber, cyclized rubber, and reclaimed rubber, can be prepared. This type of glue is inexpensive but has poor strength. The vulcanized rubber glue is made by adding vulcanizing agents, vulcanization accelerators, reinforcing agents, tackifiers, antioxidants and other compounding agents to the raw rubber after mastication. It is made by dissolving in organic solvent after mixing. This glue has better performance, so it has a wide range of applications
