WACKER® L 656 is an aminoalkyl functional polydimethylsiloxane. In comparison with other curable amino silicone fluids, WACKER® L 656 exhibits an increased storage stability both as 100 % fluid and in ready-to-use formulations.

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.



The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
