Description :

Sikadur®-31 SBA Cold Weather is a two-component, cold weather, 100% solids, moisture-tolerant, highmodulus, high strength, structural epoxy adhesive designed for bonding hardened precast concrete to hardened precast concrete in segmental bridge construction. It conforms to the current ASTM C-881, Type VI requirements, ASBI guidelines and is CE Marked to EN 1504-4.

Uses :

Sikadur®-31 SBA Cold Weather may only be used by
experienced professionals.

• Structural bonding of post-tensioned precast concrete bridge segments.
• Sealing joints between concrete segments.
• For use in segment-by-segment erection. Segmental bridge construction in cold temperatures -6°C to +7°C.
• As a bonding bridge between new and old concrete.
• A structural adhesive to rigidly bond most construction materials, including:
  fresh concrete to hardened concrete precast concrete elements hard natural stone ceramics and fibre cement mortar, bricks, masonry and renderiron and steel wood polyester, fibreglass, epoxy and polyurethane

Characteristics/ Advantages :

• Application temperature range: -6°C to +7°C.
• Easy to mix and apply.
• Suitable for dry and matt damp substrates.
• Moisture tolerant before, during and after cure.
• High-modulus, high-strength, structural adhesive.
• Curing times to meet assembly and strength gain requirements.
• Easy to apply, non-sag for vertical applications.
• Excellent adhesion to concrete, steel and most construction materials.
• Convenient, easy to mix ratios (A : B = 2 : 1 by volume).
• Colour-coded components to ensure proper mixing control.
• No primer needed.
• Hardens without shrinkage.
• High initial and ultimate mechanical strength.
• Impermeable to liquids and water vapour.
• Good chemical resistance.
• Enables construction projects to continue, even during freezing conditions.
