Weld-On #58 Cement

Weld-On #58 is a fast curing, clear-colorless, two-component, 100% reactive polyurethane adhesive that contains no volatile organic compounds (VOC). When mixed and applied, it polymerizes at room temperature to form high bonds within a few hours. The adhesive has excellent resistance to discoloration by UV light and has excellent lap shear and impact strength. Weld-On #58 is recommended for a variety of applications in the sign assembly industry, especially butyrate trim cap to polycarbonate in channel letter applications. It also has many uses in other plastic fabrication industries for bonding ABS to PETG.

• PROFESSIONAL-GRADE FORMULA — Weld-On #58 cement is engineered for strong, durable bonds on compatible plastic substrates. Designed for demanding fabrication and repair environments where joint integrity is critical. Ideal for applications requiring a reliable, solvent-based cement that penetrates and fuses plastic surfaces for a structurally sound, lasting bond.
