2/1 epoxy used for anticorrosive/chemical resistant/water tolerant applications. Ideal for wastewater plants.
100% SOLIDS EPOXY HEAVY DUTY PROTECTION
BIO-GARD 251 is based on pure liquid epoxy polymers and aliphatic amine curing agents. Pigmentation is selected for hardness and durability in order to obtain the best possible properties in the cured film.
BIO-GARD 251 is formulated with no volatile solvents and is so completely tolerant of water that it may be applied to damp or wet surfaces yet still function well as an anticorrosive barrier coating. Applications may be made using brush or roller with no especial ventilation requirements – odor during application is almost completely absent. Airless spraying using heated, 2/1 plural equipment is easily accomplished at a fluid temperature of 140’F. The standard “00000” version may be shipped “Non-Regulated” by air or surface -this material is ideal for most applications however it will yellow on exposure to UV light.
BIO-GARD 251 has been successfully tested against ANSI N-101.2 and ASTM 3911, (340’F BWR curve), criteria for Radiation and DBA in nuclear applications. (Radiation dose rate was 2.2 x 10(6) rads/hour for a total of 1.1 x 10(9) rads @ 79’F).
