Prime Flex 985 LX 20

Prime Flex 985 LX20 is a polyurethane foam that fills voids behind and under structures. This versatile product is a two-component, low exotherm polyurethane foam used to fill voids, stabilize soil and underseal concrete slabs. Its low viscosity (270-280 cps) allows for moderate permeation effects as well. This formulation has double the expansion capacity of Prime Flex 985 LX10. It has been independently tested and certified to meet NSF/ANSI Standard 61.5 for contact with potable water.

We also produce Prime Flex 985 LX20 Fast, which has the same features but with much faster reaction times. It reacts in 12 seconds versus 68-70 seconds and reaches full rise at 65-85 seconds versus 6-12 minutes.
