SiMP-Seal 25 HM

One-part SiMP high modulus construction sealant

SiMP-Seal 25HM is a one-component, gun-grade, non-sagging SiMP – Silyl Modified Polymer high modulus construction sealant. It cures under the influence of atmospheric moisture to form a permanently elastic sealant with excellent adhesive properties and resistance to ageing and weathering. Solvent- and isocyanate-free, it has 0 VOC. Outstanding body and thixotropy. Certified according to: EN 15651/1 TYPE F INT/EXT; EN 15651/4 TYPE PW INT/EXT; EN 15651/3 TYPE XS3 Compliant to: ISO 11600 Type F Class 20 sub-class HM LEED iEQc 4.1 ; SCAQMD Rule 1168 ; BAAQMD Reg 8 Rule 51 CARB VOC levels regulation
  • Permanently elastic over a wide range of temperatures; accommodates joint movement of ±20%
  • Non-sag, exceptional thixotropy and short cut-off string
  • Excellent primerless adhesion on all typical construction materials and substrates
  • Excellent resistance to ageing and weathering; color stable and non-yellowing
  • Sealing and bonding between different materials like metal, plastic, glass
  • Sealing joints in vertical and horizontal applications
  • Metal roof and gutter sealing
