TOLSA Showcases PANGEL® Series of Additives at American Coatings Show 2018 in Indianapolis

MADRID, Spain, February 27, 2018 – TOLSA, based in Madrid, a leading global supplier of specialized additives for the paints and coatings industry, will showcase its industry-leading portfolio of rheological additives based on high-purity sepiolite technology, at the American Coatings Show (ACS) 2018 (Booth #2265) April 10-12 in Indianapolis.

TOLSA will highlight its broad range of products and the performance of its high-growth U.S. additives business which has emerged as a formidable supplier to the paints and coatings market. TOLSA has built a strong foundation in the U.S. by producing unique additives for water-based and solvent-based systems. The company has experienced strong growth over the last several years and its long-term strategy is to expand its resources and capabilities with new investment in technology, manufacturing, capital, and personnel.

“With our broad product portfolio we are firmly positioned as a strategic supplier to the U.S. market,” said Michelle Mercurio, sales director for TOLSA USA. “Our innovative technology has now been validated in the U.S. and we continue to see strong results as our products gain market share.”

TOLSA has built a strong foothold in the U.S. market with sales and technical offices in Casper, Wyo. and a warehouse located in Addison, Ill. The company has a broad distribution network which includes partners such as MSullivan, TCR Industries, Chemo, and DarTech. TOLSA owns one of the largest and highest purity sepiolite mines in the world in Madrid.

At the ACS show, TOLSA will highlight the PANGEL® series of rheological additives for water-based and solvent-based paints and coatings. The product range is based on a wide variety of special clays, including sepiolite, attapulgite, montmorillonite, and saponite with each sharing the capabilities of easy build up, shear thinning, and thixotropic gel structures.

PANGEL® additives are composed of extremely high-purity sepiolite minerals. TOLSA developed the technology required for purification and production of highly efficient and very low-crystalline silica additives which are unique in the industry. These two key characteristics make them extremely good candidates as attapulgite additives alternatives.

A key feature of PANGEL® technology is its ability to yield fewer defects when incorporated into a coatings system, thus providing a competitive advantage for the end-user. PANGEL® products are characterized by the “3S” benefits they deliver: settling, sedimentation, and syneresis. They are particularly efficient in architectural and industrial coatings where solids content and filler density often drives strong variations in coatings stability.

Broad Product Portfolio Meets Market Demands

PANGEL® series products are sold as micronized solids. Their dispersion process is similar to that of other solid components of the formulation, ensuring an appropriate wetting of the product and application of sufficient mechanical energy (shear).

For water-borne systems, TOLSA offers the PANGEL® S series, produced from high-purity sepiolite with outstanding suspension and anti-sagging capacity unaffected by electrolytes. PANGEL® S9, a purified sepiolite, is one of TOLSA’s leading products, offering high-shear thinning. It is normally used as a co-thickener with HEC or associative thickeners for improving syneresis and sedimentation and replaces attapulgite thickeners at half dosage. Other products for water-borne systems include the PANGEL® W series, specifically developed to enhance thickening and anti-sagging properties with water retention and excellent brushability, and the PANGEL® M series, produced from high-purity bentonite for easy gelling and dispersing capacity.

Products for solvent-based systems include the PANGEL® B series which are rheological organoclay additives based on high-purity sepiolite with extra performance and additional suspension capacity, anti-sagging, and homogenizing; and the PANGEL® OM series, rheological organoclay additives based on high-purity bentonite for easy incorporation. The PANGEL® OMD series consists of self-activated organoclay additives based on high-purity bentonite for easy incorporation into solvent-based systems.

TOLSA will hold a special customer reception during the show at the Hilton Indianapolis. Those interested in attending can contact
