Non-skinning butyl sealant for standing seam roofs

SikaLastomer®-511 is a non-skinning and non-corrosive butyl rubber-based sealant. It remains malleable so that the sealant can be factory dispensed and then joined in the field, depending upon the temperatures at which the panels are stored. Metal panels can be easily separated after extended periods for repair and maintenance.  

  • Very good adhesion to common standing seam substrates
  • Good pumpability and gunnability
  • Panels can be bonded in the field up to 6 months after initial application
  • Contains additive to inhibit a broad spectrum of microbial activity
