  Why SIKA?

SIKA offers a line of professional-grade polyurethane (Sikaflex) and silicone (Sikasil) sealants along with epoxies and structural adhesives (Sikadur) with outstanding performance properties for demanding applications. Benefits include: 

  • Superior Adhesion - Will bond to more surfaces, particularly porous substrates such as concrete and masonry, without using primer. 
  • Dirt Resistance - Designed to exhibit far less dust and dirt pick-up during cure and over the lifetime of the building. 
  • Substrate Straining - Will not stain or discolor virtually on any common substrate. 
  • Paintability - Can be treated with most coatings and paints without the risk of delamination.
  • Water Immersion - Can be placed in totally immersed environments without being affected by the action of the water. 
  • Industry Certifications - Variants certified to ANSI/NSF 51 for food contact, ANSI/NSF 61 for potable water, UL fire ratings and ASTM C-920 and ASTM C-881 for construction applications.
