EPDM membranes leech chemicals through the top of the membrane for most of their useful service lives. This leeching causes all silicone roof coatings to turn yellow. EPDM Bleed-Block Primer simultaneously enhances adhesion while also preventing yellowing of the coating. P-110 is a plasticizer free, single component, water-based, acrylic primer designed to prime properly cleaned EPDM surfaces.
Limitations & Precautions:
This product cures only by water evaporation. P-110 should not be applied when the ambient temperature is below 50°F, or if there is a possibility the temperature could fall below 32°F within 24 hours. Application is not recommended if rain or dew is expected before product dries.
P-110 EPDM Bleed-Block Primer is available in 55 gallon and 5 gallon containers.
