Product lineup

As your full-service partner, we tailor product development to your unique requirements. Our Paul F. Werler Innovation Center can support ANSI standards and even conduct testing for you. Below are just some of the products we have developed for construction material customers. Contact us to talk about your specific needs.

GlucoSol® Series

These highly substituted natural polysaccharides are value-added alternatives to competitive natural and synthetic water-soluble polymers. GlucoSol polymers cause individual particles to briefly wet-out prior to rapid hydration, eliminating the formation of gel agglomerates typical of other water-soluble polymers.

GlucoStar® Series

Chemstar’s GlucoStar series provides a number of advantages for construction material products, including rheology modification and water retention properties.

StarBond® Series

The Chemstar StarBond series brings exceptional adhesion and binding properties to a variety of essential compounds used within the construction material industry.
