What is TMPTA Monomer?

1. TMPTA belongs to polyol acrylate, which is an important multifunctional monomer with high activity. The trimethyl propylene dilute acid ester has high molecular double bond content and fast curing speed. It is an excellent crosslinking agent and curing agent. Due to the high boiling point of Trimethylolpropane triacrylate, there is no solvent volatilization during the curing process. It is not only environmentally friendly, but also highly energy-saving. Therefore, it is widely used in many fields such as coatings, adhesives, inks, electronics, and rubber. The synthesis of trimethyl propylene triacrylate is of great significance.

2. TMPTA is a newly developed variety in the acrylic series products, and is an important trifunctional acrylate functional monomer. Because TMPTA has the characteristics of high double bond content, fast curing speed, low viscosity, high boiling point, low volatility, etc., it has become the most widely used and the largest amount of multifunctional acrylic reactive crosslinking diluent in the field of radiation curing. At present, TMPTA is mainly synthesized by the direct esterification of trimethylpropane (TM) P and acrylic acid (AA) or the transesterification of TMP with methyl acrylate (MA). Most of the catalysts used in this process are sulfuric acid or p-toluenesulfonic acid. [‘Several due to equipment corrosion and complex processes such as neutralization and water washing during post-treatment, the product cost is relatively high. The author uses trimethylpropane and acrylic acid as raw materials, sulfuric acid as a catalyst, cyclohexane and toluene as a water-carrying agent, and a mixed system of hydroquinone and phenoin as a polymerization inhibitor to synthesize TMPTA, which has achieved good results.

3. TMPTA Monomer is a versatile monomer with a wide range of industrial applications as a crosslinker, reactive diluent and chemical intermediate.TMPTA Monomer is used in the production of UV-curable inks, electron beam irradiation-curable coatings, thermal papers, plastic hardeners, optical fibers, UV-curable acrylic varnishes for the furniture industry, polymers and resins; TMPTA Monomer is used as a component of photopolymers and flexographic printing plates and photoresists; and as a component of acrylic glues, adhesives and anaerobic sealants.

Trimethylolpropane triacrylate Usage

1. TMPTA Monomer (TRIMETHYLOLPROPANE TRIACRYLATE) is a widely used reactive diluent in ultraviolet light (UV) and electron beam (EB) curable coatings and inks.

2. TMPTA can be used as a vulcanization activator for special rubber. Special rubbers such as ethylene propylene rafter rubber and EPDM rubber, chloro rubber, silicone rubber, polyurethane, ethylene/vinyl acetate copolymer (EVA), chlorinated polyethylene elastomer (CPE), etc. are difficult to vulcanize, and organic Peroxide (such as DCP, BPO) is vulcanized. If a single organic peroxide is used for vulcanization, the vulcanization time is too long and the vulcanization is insufficient, and it is difficult to ensure good mechanical and physical properties. Therefore, TMPTMA must be added as a vulcanizing aid to achieve good results.

3. For example, organic fluorine rubber, etc., when using DCP for vulcanization, if the additive 1~4% TMPTMA is used as a vulcanizing agent, it can not only greatly shorten the vulcanization time, increase the degree of vulcanization, reduce the amount of DCP, but also significantly improve the mechanical Strength, wear resistance, solvent resistance and corrosion resistance etc.

4. In the vulcanization process of fluorine-containing rubber, the double bond in the TMPTMA molecule not only participates in the vulcanization cross-linking reaction, but also acts as a hydrogen halide (HF, HCL, etc.) acceptor to absorb the hydrogen halide released during processing , Which not only improves the quality of products, but also greatly reduces the corrosivity of vulcanized rubber. The rubber compound containing TMPTMA has a plasticizing effect during mixing and a hardening effect after vulcanization.
