Simacryl ECH-631 is most often used in conjunction with harder polymers to increase extensibility and flexibility when used as the sole resin binder. It should be formulated with plating and drying auxiliaries such as waxes, proteins or dulling agents. It is non-yellowing and thus especially good for formulating while and pastel base coats.
It is recommended to store Simacryl® ECH-631 in sealed packages and keep it above 5°C to protect it from freezing.
Simacryl ECH-631 is a medium soft, tough, tack free acrylic emulsion of ultra fine particle size, showing extraordinary versatility as a finishing resin for a broad range of leathers. It is employed in both impregnation and base coat formulations for full grain and corrected grain leathers.
