Alkaline/Caustic suitable RG (Resistant Grey) range is ideal in applications that are indoors or external but not exposed to UV as they are non-UV resistant. The application for these products is ideal in indoor food processing areas where caustic bulk washdown foaming agents are used in the cleaning process such as in abattoirs and meat processing including fish and poultry. They are also good performers in areas where cooking oils or fatty residue may build up on surfaces.
