Description
SG635 is a 300 kg density PVC foam which is coated both sides with high tack acrylic adhesive with blue filmic liner for easy release. SG635 has an open cell structure to allow curing of structural silicones on all sides of the joint.
Usage / Purpose
SG635 is designed to give a specific gap thickness for structural silicone in structural glazing systems. The open cell nature of the foam allows curing of structural silicones.
Colour
Black or grey to special order.
Sizes
3 mm, 4 mm, 5 mm and 6 mm thickness available in any width from 6 mm up to 980 mm.
8 mm 9.5 mm and 12 mm from 8 mm up to 980 mm.
Packaging
Multiple rolls in boxes with silicone interleaves
Standards
Tested to ASTM E96-2005 water vapour transmission to determine open cell airflow structure. Tested for use with SG200 Proglaze II.
Preparation
All contact surfaces must be clean, dry, smooth and free of grease and contamination. Adhesion is very quick and increases over 24 hours, therefore position tape as accurately as possible and reposition very quickly if necessary. It is advisable to run evaluations to ensure that all surfaces are compatible with our tapes.
Health & Safety Precautions
Safety Data Sheet must be read and understood before use.
