如何选择分散剂型号

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.

分散剂Houhuan 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, 等. are all very useful.

无有机树脂彩色膏的主要分散剂有: HH2021, HH2305, HH2681, HH2690, HH2018 等型号, 也可用于无树脂无机粉末.

另外, 用于含无机颜料填料的二氧化钛金红石二氧化钛粉的研磨, 推荐使用 HH2019 分散剂, 效果也非常好.

以上, 我们讲了有机和无机颜料粉末的水性体系无树脂彩色膏分散剂, 所以有些客户问, 含树脂的怎么办? 通常, 可以使用无树脂的, 更多使用含树脂的. 添加树脂后, 成膜性更好, 最终产品的附着力, 耐候性, 耐化学性都得到改善, 涂层使用寿命也更长.

所以如果可以使用无树脂分散剂, 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. 同时, we welcome more discussions and sharing about dispersant issues with us.
