SCIGRIP SG46C is a high-performance, translucent acrylic adhesive designed for assembly and fabrication applications requiring invisible bond lines with no read through.
Engineered to bond primerless aluminum or other metals to acrylics, polycarbonate, and other plastics, it is trusted by manufacturers in the sign industry and fabrication sectors worldwide.
From bonding metal frames to acrylic panels and assembling display cases to manufacturing electrical equipment, SCIGRIP 46C delivers strength, clarity, and reliability where invisible bond lines matter most.
With UL 746C approval for use in electrical equipment assemblies for indoor and outdoor signage applications, it meets stringent quality standards while offering exceptional clarity retention, short fixture times, and a translucent cure that eliminates bond line read through.
Sign and display fabrication – Proven performance for bonding acrylic to aluminum frames, creating museum-quality display cases, point-of-sale displays, and illuminated signage where invisible bond lines are essential.
Electrical equipment assembly – UL 746C approved for indoor and outdoor signage applications, making it ideal for bonding components in electrical signs and display equipment that require certification.
Manufacturing and fabrication – Widely used for bonding metal frames to plastic panels, assembling multi-material components, and creating products where aesthetic appearance and bond line invisibility are critical.
Metal-to-acrylic bonding specialist – Exceptional performance bonding aluminum, steel, and stainless steel to acrylic, polycarbonate, and other clear plastics without visible bond lines or finishing requirements.
Aquarium and display case manufacturing – Perfect for creating high-quality aquariums, museum cases, and protective displays where clarity, strength, and invisible bonds are essential for professional results.
