Seamsil® Silicone Systems

Edge Sealing and Protection – Metal Roof Sealant For Leaks & Repairs

SEAMSIL® is a unique flexible silicone remedial system developed by Delvemade Limited in conjunction with GE Silicones, part of the General Electric Company of America.

The system, initially developed to solve the problem of cut edge corrosion on steel roofing has now become recognised as the most versatile and effective protection treatment in any situation where exposed metal is subjected to aggressive moisture conditions. For this reason, manufacturers across a variety of industries are specifying SEAMSIL® in the production of fabrications where resistance to corrosion damage is a requirement. Making it a prime roof sealant.
