BYK D420

BYK D420 is a liquid rheology additive for aqueous detergents, cleaning and care products and water-reducible coating systems for improving anti-sagging and anti-settling properties. The additive is also especially suited for manufacturing aqueous pigment concentrates. In detergents, cleaning and care products, after being incorporated into the system, the additive generates a three-dimensional network structure. The resulting thixotropic flow behaviour is ideal for preventing particles (eg encapsulated fragrances) from settling, without negatively impacting the residual emptying of the container. Cleaning products with BYK-D 420 are easy to use and can be applied by spraying. The use of the additive improves adhesion to vertical surfaces, which improves the cleaning action as a result of the longer exposure time. The additive is liquid and therefore easy to handle. It is not necessary to specifically adjust the pH value or control the temperature during incorporation. BYK-D 420 is stable to acids and bases in a pH range of 0–13. The electrolyte resistance and compatibility with surfactants, including cationic surfactants, are excellent. The transparency of the detergents and cleaning products is preserved.
