Description:

Nitofill UR63 is a two part liquid polyurethane which reacts to form a tough, slightly flexible resin. Nitofill UR63 has good adhesion to concrete and masonry and when injected into cracks it allows some movement without loss of bond.

Uses:
For injecting into cracks in concrete or masonry in wet conditions to form a slightly elastic seal.

Advantages:

•  Low viscosity – penetrates fine cracks and cavities
•  Reacts with water and forms flexible closed cells that allow the movement of the crack
•  Flexible to withstand differential movement
•  Free expansion: 800%
•  Chemically resistant against water, weak acids, alkali and micro-organisms
• Excellent adhesion to mineral construction materials (such as concrete, cement, brick and mortar) and metal
•  Reaction speed is controlled by varying the amount of hardener. Use 6-9% hardener to achieve a good cell structure.
