Description
Weld-On® 58 is a fast-curing, clear two-component polyurethane adhesive designed for sign and plastic fabrication. Ideal for bonding trim cap to polycarbonate in channel letters, this reactive adhesive delivers strong, UV-stable bonds in minutes. Its shorter working time and high clarity make it a go-to choice for production environments requiring speed and strength.
Preferred by Sign Fabricators for Speed
Weld-On 58 is trusted by professionals needing rapid fixture times without sacrificing bond clarity or strength. It’s particularly effective in channel letter assembly and general plastic fabrication where ABS, PETG, and polycarbonate are commonly used.
