Silirub IS - Industrial Seal is a high performance neutral cure silicone sealant with outstanding adhesive/sealing properties for most of the industrial critical applications. Silirub IS - Industrial Seal has been tested on di-electrical properties and is FDA (food grade) approved by Ianesco (France).
One component RTV (Room Temperature Vulcanising).
Can be applied to overhead or vertical joints.
Does not crack, crumble or dry out in direct sunlight.
Bonds almost all surfaces: Clean metalincluding chrome, painted surfaces, glasses, ceramics, most plastics, non-oily woods, fibrous cement and concrete surfaces.
FDA approved (food grade)
Excellent UV resistance
Sealing of solar panels & junction boxes
Silirub IS – Industrial Seal is the most suitable Industrial grade Silicone Sealant.
