Description
Formulated for assembly and fabrication applications that require clear bond lines with no read through
Weld-On/SCIGRIP 46C is a two-component, clear, thixotropic, reactive acrylic adhesive for bonding primer-less aluminum or other metals and acrylics. Its characteristics make it an excellent choice for sign assembly and other fabrication or manufacturing uses where no sagging, short fixture times, and good clarity retention are required.
SIGN & DISPLAY MANUFACTURING
Weld-On/SCIGRIP 46C’s strong clear adhesive is a game changer when it comes to bonding trim cap to polycarbonate lettering. Because it cures clear, no bond lines show through when the sign is back lit.
Performance Benefits
