LOCTITE PC6231

Main features

  • Rapid 90-Minute Full Cure
  • Self-Leveling Low-Viscosity Fill
  • 10-15% Joint Movement Capability

Product Description

LOCTITE PC 6231 Rapid-Curing Concrete Joint Filler is a two-part, 1:1 mixed, self-leveling material for filling and repairing interior control joints and new saw-cut joints in horizontal concrete. The 100% solids, low-viscosity system gels in 3 minutes and cures in 90 minutes at 24 deg C, allowing traffic after full cure. It accommodates 10% to 15% movement of installed joint width. The cured material combines 1.9 N/mm^2 adhesion to concrete, 82% elongation, and Shore A 75 to 80 hardness for heavy-traffic and freezer-floor applications.

Key features

  • Rapid 90-minute cure: Gels in 3 minutes and reaches full cure in 90 minutes at 24 deg C.
  • Self-leveling joint fill: A mixed viscosity of 525 mPa s supports gravity feeding into prepared horizontal joints.
  • Controlled joint movement: Accommodates 10% to 15% movement of installed joint width.

Applications

Applications include interior control joints, new-construction saw-cut joints, heavy-traffic industrial floors, freezer floors, and exterior horizontal concrete with minimal thermal movement.
