Sikadur®-31 SBA S-02 IN

Segmental bridge adhesive for use at +25 °C to +45 °C

Sikadur®-31 SBA S-02 IN is a 2-part epoxy based moisture tolerant, thixotropic, solvent-free, structural adhesive especially formulated for segmental bridge construction. It has good squeezability, high initial strength gain, hardens without shrinkage and complies with many international and national standards such as FIP, ASTM etc. Application temperature range +25 °C to +45 °C.

  • Meets and / or exceeds International and National Standards (such as FIP, BS, ASTM etc.)
  • Lubricates the surfaces and makes positioning of the shear keys easier
  • High strength and high modulus of elasticity

Usage

Sikadur®-31 SBA S-02 IN is used as segmental bridge adhesive for use on substrate temperatures of +25 °C to +45 °C.     Sikadur®-31 SBA S-02 IN in segmental bridge construction:

  • Provides a watertight joint between segments
  • Lubricates the surfaces
  • Transfers the loading stresses between segments
