Tyzor® NPZ, zirconium tetra-n-propanolate

Tyzor® NPZ is a reactive alkoxy zirconate that is used as a cross linking agent for dispersions of guar used in oil well fracturing fluids.
Product Overview
Tyzor® NPZ is a 74% active solution of tetra-n-propyl zirconate in n-propanol. It is an excellent cross linking agent for polysaccharides and polymers containing hydroxyl or carboxyl functional groups. Tyzor® NPZ is most commonly used to cross dispersions of guar to form highly viscous gels used in oil well fracturing. It can also be added to paints to cross link polymers and promote adhesion. Tyzor® NPZ can form polymeric films of zirconium dioxide. It is used as a surface modifier to promote adhesion of coatings, increase scratch resistance, improve light reflection, and add coloring effects. In chemical manufacturing operations, Tyzor® NPZ is used as a low toxicity Lewis acid and Ziegler-Natta catalyst. It eliminates by products and improves yield of esterification, condensation, and addition reactions.
