Working with Techsil’s Business Development Manager, Steve Morrow, several options were evaluated. A semi closed cell EPDM foam tape called SF031 looked like the best solution. This double sided foam tape consists of an EPDM foam carrier with semi-closed cells and an acrylic adhesive. SF031 has a good resistance against UV light, water, wind, humidity, high and low temperatures, chemicals, such as acids and alkalis, and has very good sound damping properties. It has a flexible carrier that provides an excellent seal, even if the surface expands or contracts due to temperature changes, and possesses a low compression load that would not deform the roof when the sign is fitted.
Tests were done using several thicknesses;
Techsil’s die-cut tape solution provided a robust seal which protects the interior against water ingress. The new gasket has reduced costs and increased productivity.
