AF-4 is a anti-foam 'surface tension relieving'
agent manufactured by BJB Enterprises and designed
to be used as an additive for polyurethane
resins. The purpose of AF-4 is to assist in the
vacuum degassing procedure by reducing the
surface tension of entrained air bubbles within
the resin mixture. In addition, AF-4 also assists
with better resin flow and wet out in moulds.
This grade is completely silicone free and will
not affect the colour, appearance or bond
ability of cured urethane parts. AF-4 works
exceptionally well in the water clear aliphatic
urethanes.
