WACKER® L 656 is an aminoalkyl-functional polydimethylsiloxane. Compared to other curable amino silicone fluids, it demonstrates improved storage stability, both in its pure form and in ready-to-use formulations. This makes WACKER® L 656 an excellent choice as a component for rinse-off agents in automatic car washes.

Application Details
  • WACKER® L 656 can be used as a component for rinse-off agents in automatic car washes. For these formulations, WACKER® L 656 is converted into its cationic form by neutralization with organic acids and, thus, shows an enhanced affinity to car bodies. In combination with cationic emulsifiers and tensides, protonated WACKER® L 656 improves the break-down and sheeting of the water film as well as conditioning effects and gloss level. WACKER® L 656 can be applied frequently without formation of any build-up.
  • WACKER® L 656 is used in paint conditioners and paint polishes in order to provide superior gloss and detergent resistance. In comparison with conventional polydimethylsiloxanes of the series WACKER® AK, aminoalkyl functional WACKER® L 656 exhibits an excellent affinity to various substrates. Gloss and depth of color are retained for a longer period of time.
