New additives provide strong sag resistance

21.Jul.2021

Two new liquid rheology additives have been developed by our Key Supply Partner BYK to provide strong sag resistance and stable processes with zero emissions in epoxy, alkyd and polyurethane systems.

Rheobyk-7502 and Rheobyk-7503 are 100%-active micronised organic powders which meet the market requirements of various systems by increasing the sag resistance and producing a strong shear thinning effect. They are ideal for single component silane-modified polymer systems, epoxy systems and alkyd-based coatings systems.

The use of such systems for adhesive and elastic sealant formulations in construction, flooring and transportation applications makes high sag resistance and storage stability strictly necessary.

The new amide waxes, Rheobyk-7502 and Rheobyk-7503, have been specially developed to meet the requirements of these systems by creating unique pseudoplastic flow behaviour. The mechanical properties remain unaffected.

Key benefits of the additives include:
