WILLSTOP^® FLEX+ is a light brown, water-reactive liquid. The product is already catalysed and characterized by its high flexibility and elasticity.
When WILLSTOP^® FLEX+ comes into contact with water, it expands and quickly hardens into a tough, flexible, closed-cell polyurethane foam. Reactivity is dependent on temperature.

Advantages:

• Pre-catalysed
• reacts at temperatures below 5°C
• phthalate-free resin

WILLSTOP^® FLEX+ can be further accelerated by adding up to 2% (parts by weight) of WILLADD^® Flex.
