General Information:
In today’s coatings chemistry, TMPMP has emerged as a unique monomer with sulfhydryl functional groups. Its high reactivity enables it to rapidly and efficiently participate in chemical reactions during the curing process of coatings, greatly reducing the time required for coating film formation, which is of great significance for the improvement of industrial production efficiency. Compared with some traditional monomers, TMPMP’s low viscosity makes its addition to the coating formula smoother, and it can be better mixed with other ingredients, thus ensuring good leveling of the coating during the painting process, and making the final surface of the coating more flat and smooth, with a better texture.
From the perspective of environmental protection, TMPMP is undoubtedly a product in line with the development needs of the times. Against the backdrop of the global push for VOC standards to control volatile organic compounds (VOC) emissions, TMPMP has become an ideal choice for many paint manufacturers due to its low color and low VOC content. For example, in the renovation of places with high indoor air quality requirements, such as kindergartens and hospitals, the use of coatings containing TMPMP can effectively reduce the release of harmful gases and create a healthier and safer indoor environment for people.
In terms of practical application, TMPMP has excellent compatibility. It synergizes with isocyanates to build a tough and durable coating film structure through the formation of chemical bonds, which not only has good abrasion resistance, but also effectively resists external environmental factors such as ultraviolet rays, moisture, etc., which greatly extends the service life of the coating. When combined with epoxy resin, TMPMP can improve the flexibility of epoxy resin after curing, so that it can better adapt to the deformation of the substrate without cracking or peeling off phenomenon in some occasions that need to withstand a certain degree of deformation, such as anti-corrosion coatings for metal pipelines and protective coatings for bridges. When used with unsaturated compounds, TMPMP can participate in the free radical polymerization reaction, providing unique properties for coatings, such as enhancing the gloss and hardness of the coating, so that it shows excellent decorative and protective properties in the field of furniture painting, automotive top coatings and other fields.
