Tremco SG635 Structural Glazing Spacer Tape
Sealing & Bonding Products

Tremco SG635

SG635 is a high-density PVC foam tape designed to give a specific gap thickness for structural silicone in structural glazing systems. The foam is coated both sides with high-tack, pressure-sensitive acrylic adhesive with blue filmic liner for easy release and its open cell nature allows curing of structural silicones. Available in a range of widths and thicknesses to suit a range of structural systems.

Structural glazing operations should only be carried out after consultation with an FG Trading technical representative. Please note that SG635 is a spacer tape and not intended for use as a structural component. It is advisable to run evaluations to ensure that all surfaces are compatible with the tape.

Please see data sheet for more information. Please do not hesitate to contact us for further information, pricing or to discuss your sealing & bonding requirements.
