Kor-Chem BIO-4 is a versatile, water soluble ink degradent and stain remover for use on textile and graphic inks. Formulated using biodegradable and organic compounds that make Bio-4 environmentally acceptable, safe and highly effective. Bio-4 begins to work on contact by immediately penetrating, dissolving and removing plastisol, UV, water based, conventional/solvent based, enamel, epoxy and vinyl inks from screens. Bio-4 has non-caustic stain removers built-in which aggressively remove image stains without harming the mesh. Bio-4 rinses freely and easily with water and has a very pleasant cherry scent.
