BYK´s first polyamide-based rheology additive for aqueous systems: RHEOBYK-440. RHEOBYK-440 – Liquid, Polyamide-based Rheology Additive for Modern Aqueous Systems. Over the past years, the focus of developments in protective coatings has increasingly moved to aqueous systems based on epoxy dispersions. These coatings are highly pigmented and applied in thick layers, requiring the rheological properties to be controlled using a suitable additive. The established products are only slightly or even not at all effective, and some are completely incompatible in epoxy dispersions.
RHEOBYK-440, however, is a tailor-made solution for these modern, water-based systems. It does not only provide outstanding anti-sagging and anti-settling properties in aqueous protective coatings, it is also recommended for usage in many other applications such as automotive coatings, general industrial coatings, wood and furniture coatings, architectural costings and floor coatings. RHEOBYK-440 can also be used e.g. to achieve a good effect pigment orientation. As usual, we ask you to find all product details and background information in the sales promotion package.
