SCHWEGO® flow 6533

Levelling additive for water-based coating systems

Chemical base: Solution of polyether-modified polysiloxane
Properties: SCHWEGO flow 6533 provides a large decrease in surface tension in aqueous systems and therefore improves substrate wetting and leveling in particular. Foam stabilisation does not occur or only very minimally and recoatability is not affected. The additive does not increase surface slip. If higher surface slip is desired, we recommend combining it with a polysiloxane such as SCHWEGO mar 8311 / 8305.
Applications: SCHWEGO flow 6533 is recommended for aqueous coatings, printing inks and overprint varnishes.
Technical data:
(Guide values)
Appearance : clear - slightly turbid, colourless liquid
Density (ISO 2811-1) : 0,92 g/cm³
Flash point (ISO 1523) : 43,5 °C
Processing: The dosage of SCHWEGO flow 6533 is 0.1 - 1.0 % calculated on total formulation. SCHWEGO flow 6533 is preferably added to the finished formulation. It can, however, be added an any stage during production.
Storage: Stir SCHWEGO flow 6533 up before use. Keep it in a cool, well-ventilated place. Subject to appropriate storage, the described properties of SCHWEGO flow 6533 are stable for at least 2 years, provided the original container is closed after use.
Packaging: 50/175 kg drum
