Specification of Fosroc Nitofill UR63
Description Nitofill UR63 is a two part liquid polyurethane. When mixed in the proportion supplied they react to form a tough, slighly fl exible resin. Nitofill UR63 has a good adhesion to concrete and masonry and when injected into cracks it allows some movement without loss of bond.
Uses
Can be injected into cracks in concrete or masonry in dry or damp conditions to form an elastic seal.
Use with Nitofill WS60 to seal cracks in wet conditions in basement, subways and tunnels.
Advantages
* Low viscosity : Penetrates fine cracks and cavities.
* Good adhesion : Adheres strongly to dry or moist concrete
* Flexible : Strong but flexible to withstand differential structural movement.
* Tough : Withstands high hydrostatic pressures
* Impermeable : On curing, it forms a hard mass impermeable to water
* Suitable for use in high temperature conditions
