Supplying mixed material on demand reduces concerns over pot life and related changes in material viscosity. On demand mixing also helps eliminate the hazardous waste and cleanup associated with batch mixing. The Hydra-Cat’s variable ratio flexibility allows use with multiple coatings from multiple suppliers without having to purchase new equipment.
