The TOYOMELT™ P-201 Series of UV-curable hot-melt adhesives achieves heat resistance of 100 °C and higher. This feature makes these adhesives suitable to meet the industrial demands of bonding steel components in high-performance applications such as automotive and electronics devices. In addition, the P-201 Series applies an instant-cure technology for immediate tack and bonding ability, eliminating the need for the aging process. This leads to faster processing speeds and improved productivity for adhesives processors.

The TOYOMELT P-201 Series of UV hot-melt adhesives was designed to address the environmental challenges related to solvent-based adhesives and the durability issues of hot-melt types. Solvent adhesives typically require drying and aging, which results in costly time losses before the material can be shipped or transferred for secondary processing. The energy costs and environmental impact associated with the drying process have also been identified as challenges by the industry.

To overcome heat-related issues associated with more conventional hot-melt adhesives, Toyochem engineers in Japan applied UV-curing technology to chemically crosslink the hot-melt adhesive by UV irradiation. “UV-curing technology offers an opportunity to create crosslinked structures that exhibit higher heat resistance at temperatures of 100 °C or more. This makes it possible to do things that had been difficult to achieve with conventional methods,” said Taichiro Matsuoka, division director of Toyochem’s Packaging & Industrial Materials Sales Division. “Promising results in curing and heat resistance open new market opportunities for our customers, in particular in high-performance applications like the bonding of steel components in automobiles or electronics devices. The new TOYOMELT P-201 Series expands our solvent-free adhesive range to our customers, as we continuously work to help them reach their technical and sustainability goals.”

In early evaluation testing, the TOYOMELT P-201 adhesives demonstrate superior bond ability with difficult-to-adhere substrates of plastics like polyethylene and polypropylene, metals such as aluminum and stainless steel, and glass. Furthermore, P-201 adhesives maintain a rubber-like flexibility even after they are cured or hardened, making it possible to bend and deform the adhesive without breaking.
