Water-based emulsion that provides excellent water repellency to different textiles, nonwoven and technical papers.

PFAS have been used in the textile, leather and technical paper industries for the past decades to improve the properties such as water resistance. Regulatory bodies in Europe and in the US are taking actions against PFAS due to their harmful effects on human health and the environment. To meet the demand for alternative water repellent agents, we present SEQUAPEL™ 409, an anionic stearylated polymer dispersion, designed for the use as sizing agent with very good water repellency.
SEQUAPEL™ 409 sizing agent uniquely provides excellent water repellency and holdout properties. It is a water-based emulsion and acts as a sizing agent for paper and paperboard as well. Compatible with most coating ingredients, this product exhibits excellent temperature and mechanical stability.
Furthermore, SEQUAPEL™ 409 provides excellent results undiluted or diluted by spraying, full bath impregnation or surface coating and in combination with acrylic binders. The actual level of SEQUAPEL™ 409 sizing agent used depends on the degree of resistance and holdout needed and on the other components (if any) that may be used in conjunction.
