Ultraviolet-curable high-temperature adhesives to bond plastics, metal, and glass introduced by Toyochem
Summary points:
- UV-curable hot-melt adhesives are for automotive and electronics bonding applications.
- TOYOMELT P-201 series offers instant curing and heat resistance above 100 degrees Celsius for fast processing and improved durability.
- Adhesives bond challenging materials like polyethylene, aluminum, and glass without the drawbacks of traditional adhesives.
TOKYO – Toyochem Co. Ltd. in Tokyo is introducing the TOYOMELT P-201 series of ultraviolet (UV)-curable hot melt adhesives for bonding plastics, metal, and glass components in automotive and electronics applications.
These adhesives resist heat to 100 degrees Celsius and higher, and apply an instant-cure technology for immediate tack and bonding ability for fast processing speeds and improved productivity for adhesives processors.
The TOYOMELT P-201 series of UV hot melt adhesives are designed to address solvent-based adhesives and durability issues of hot melt types.
Solvent adhesives typically require drying and aging, which results in costly time losses before the material can ship or transfer for secondary processing.
Compromised performance
While conventional hot-melt adhesives lack organic solvents or the need for drying ovens, yet compromise performance at high-temperature levels, which can cause softening or loss of bonding strength.
To overcome these issues, Toyochem engineers in Japan applied UV-curing technology to chemically crosslink the hot melt adhesive by UV irradiation.
In early evaluation, the TOYOMELT P-201 adhesives bond well with difficult-to-adhere substrates of plastics, metal, and glass -- including polyethylene and polypropylene, aluminum, and stainless steel.
