Trimethylolpropane (TMP) is a crucial fine chemical raw material with extensive applications, spanning fields such as alkyd resins, polyurethanes, unsaturated resins, polyester resins, and coatings. Additionally, TMP is utilized in the synthesis of aviation lubricants, printing inks, and serves as a textile auxiliary and thermal stabilizer for polyvinyl chloride (PVC) resins.
As a widely used chain extender in the resin industry, TMP is a key product driving the industrial upgrading of the polyols sector. Its unique molecular structure grants it a low melting point and glycerol-like polyol characteristics. TMP can not only replace glycerol in the synthesis of alkyd resins but also synergize with other polyols such as neopentyl glycol and pentaerythritol, further diversifying the types of alkyd resins. This versatility enhances the performance and adaptability of resin-based products, solidifying TMP’s pivotal role in advancing material innovation and application efficiency across industries.
Alkyd resins prepared using TMP exhibit outstanding hydrolysis resistance, oxidation stability, alkali resistance, and thermal stability, making them highly suitable for producing road marking paints. They are also widely used in the manufacturing of topcoat paints for automobiles, refrigerators, washing machines, and other household appliances. Furthermore, TMP plays critical roles in the production processes of surfactants, wetting agents, explosives, plasticizers, fiberglass-reinforced plastics, rosin esters, high-grade aviation lubricants, fiber processing agents, printing inks, and polyurethane foams, serving as a resin chain extender, textile auxiliary, and thermal stabilizer for PVC resins.
Derivatives of TMP find extensive applications across multiple fields, functioning as crosslinking agents, curing agents, emulsifiers, release agents, and catalysts. They are also employed in the fabrication of liquid membrane electrodes with high selectivity for sodium ions.
TMP is primarily used as a raw material for producing PU curing agents, synthesizing UV coatings, and manufacturing high-grade alkyd resins. In China, its consumption accounts for over 70% of the total domestic consumption of trimethylolpropane. Additionally, TMP plays a significant role in the production of polyester resins and titanium dioxide.
TMP holds a central position in the synthesis of high-end alkyd resins, which are commonly used in premium automotive paints and photo-curing agents for paints and inks. As the quality of products in China’s automotive and home appliance industries continues to improve, the demand for high-grade coatings has surged significantly. Concurrently, increasingly stringent environmental regulations have driven sustained growth in the demand for photo-curing agents. Consequently, the demand for TMP is expected to experience substantial growth in the coming years.
