ASTM D1384, D4340 and D6208

• Acid neutralizing agent protects by neutralizing corrosive acids Provides protection against acid corrosion, scale and sedimentation formation Mineral sediment preventative keeps minerals in solution, resisting formation of clusters of mineral salts and preventing particles from precipitating out of solution Undiluted, provides freeze protection to -60 deg F, minimum flow to -70 deg F and burst protection to -100 deg F 94 to 98% efficient heat transfer solution in most application dilutions Lower freeze point and higher boiling point than water Non-flammable, odorless, non-toxid and non-irritating

Cryo-Tek™ -100/AL is a blend of virgin (not recycled) propylene glycol and Hercules exclusive triple protection additives designed for use in hydronic heating and cooling closed loop piping systems (including Pex and radiant tube heating systems), ice melt and general heating systems where aluminum heat exchangers are installed. Hercules triple protection additives provide outstanding protection against acid corrosion, scale and sedimentation formation in properly maintained systems containing recommended concentrations of (No Suggestions) anti-freeze.
