SiMP-Seal 20

One-part SiMP low modulus construction sealant

SiMP-Seal 20 is a one-component, gun-grade, non-sag SiMP – Silyl Modified Polymer construction sealant. It cures under the influence of atmospheric moisture to form a high-performance compound with permanent elasticity and high resistance to ageing and weathering. Solvent- and isocyanate-free.   

Areas of Application SiMP-Seal 20 is a high quality and versatile construction sealant for expansion and construction joints in vertical and horizontal applications, joints in precast elements, external walling and cladding joints. Suitable for metal roof and gutter sealing, bridge and balcony parapets, weatherproofing of joints between brickwork, blockwork, masonry, wood, concrete, metal, window or door frames. 

Certified according to: EN 15651/1 TYPE F INT/EXT CC   ISEGA EC Regulation 1935/2004 for food contact 

Compliant to: ISO 11600 Type F Class 25 sub-class LM  LEED iEQc 4.1; SCAQMD Rule 1168; BAAQMD Reg 8 Rule 51  CARB VOC levels regulation
