Bagaimana memilih model dispersan

Recently, many customers have consulted us about color paste dispersants. First of all, customers should be clear about the properties of their pigments, such as whether they are organic pigments or inorganic pigments, whether the grinding and dispersion contains resin or not; then whether it is used in a water-based system or a solvent-based system or other systems, what products are finally applied, and what requirements need to be met, so that targeted dispersant models can be accurately provided. Today we will talk about the selection and recommendation of water-based color paste dispersants.

ភ្នាក់ងារបែកខ្ញែកHouhuan Chemical HH series dispersants currently have more than 20 mature models, so the resin-free color paste dispersants used for water-based inorganic powders are mainly: HH2003F, HH2800, HH2690, HH2010, ល. are all very useful.

The main dispersants for organic resin-free color pastes are: HH2021, HH2305, HH2681, HH2690, HH2018 and other models, which can also be used for resin-free inorganic powders.

លើសពីនេះទៀត, for the grinding of titanium dioxide rutile titanium dioxide powder with inorganic pigment fillers, HH2019 dispersant can be recommended, which is also very effective.

Above, we talked about the water-based system resin-free color paste dispersant for organic and inorganic pigment powders, so some customers asked, what about the resin-containing ones? Usually, resin-free ones can be used, and resin-containing ones are more used. After adding resin, the film formation is better, the final product adhesion, weather resistance, and chemical resistance are improved, and the coating service life is also long.

So if the resin-free dispersant can be used, then the resin-containing grinding can basically be used, but the specific problem is analyzed specifically. When selecting, it is better to understand it clearly with Houhuan business personnel before taking samples for testing, which can provide you with a more accurate match. ក្នុងពេលតែមួយ, we welcome more discussions and sharing about dispersant issues with us.
