AF-7 Anti-Foaming Agent has been developed as an extremely effective, air release agent for Water Clear polyurethane material systems. Its purpose is to assist in the vacuum degassing procedure by reducing surface tension of entrained air bubbles in the mix. When stirred in to already mixed A & B components, the AF-7 Anti-Foaming Agent works to break the material surface tension. This product is sold in a pint/approx. 473ml in volume. Note: AF-7 does not replace the need for pulling a vacuum on casting materials to eliminate air.
