Silicone-Based Adhesives for Demanding Bonding and Sealing Applications

Our silicone-based Sikasil® product line includes both one- and two-component (1C & 2C) adhesive systems. They offer excellent adhesion to glass, metals, coated metals, plastics and wood, and are designed for the most demanding adhesive and sealing applications, like those involving automated industrial processes. Sikasil® 1C systems begin curing when they react with atmospheric moisture. 2C systems begin curing at room temperature as soon as the two components are mixed, however, the process is accelerated at higher temperatures (up to 50°C).

Main Material Properties

  • 100%-Modulus: 0.9 – 1.2 MPa
  • Tensile strength: 1.5 – 2.5 MPa
  • Elongation: 200 – 500 %


Sikasil® adhesives can be easily applied using a gun or an automated dispensing system. 2C systems must be properly mixed to ensure reliable performance. Our System Engineering team is available to provide advice on selecting and setting up a suitable pump system and mixing unit.
