Tyzor® 212

Tyzor® 212 by Dorf Ketal is Zirconium chelate with approximately 52% active ingredient in 1-propanol solution. Is an organometallic catalyst. It is not affected by freezing and thawing. It is compatible with water, offers low color generation and works well over a wide pH range. It reacts with water by hydrolysis to form a reactive hydroxy zirconium chelate that is stable in water for extended periods. The original or hydrated chelate bonds with organic -OH or -COOH groups to form strong gels by cross-linking many polymeric materials and carbohydrates such as cellulose, starch and guar. It reacts similarly as an adhesion promoter on -OH functionalized surfaces. Improves film strength, adhesion promotion and rheology control. Tyzor® 212 cross-links polymers and binders in solvent-borne and water-borne coatings and printing inks. It can also be used for surface modifications of pigments.

Tyzor® OGT

Tyzor® OGT by Dorf Ketal is organic alkoxy titanate. Acts as a crosslinking agent, catalyst and as an adhesion promoter. It is a 100% active, colorless-to-yellowish organic liquid that is sensitive to moisture. It increases surface hardness, promotes adhesion, improves resistance to heat, chemicals, corrosion and scratches, adds iridescence or enhances light reflection. It is an effective catalyst for esterification, transesterification, condensation and addition reactions. Its benefits include elimination of by-products, increased yield, easy work-up, low catalyst concentration and low toxicity. Tyzor® OGT is used in glass, metals, fillers, paints and pigments.

Tyzor® TEAZ

Tyzor® TEAZ by Dorf Ketal acts as a crosslinking agent, catalyst and as an adhesion promoter. It reacts with water by hydrolysis to form a reactive hydroxy zirconium chelate that is stable in water for extended periods. The original or hydrated chelate bonds with organic -OH or -COOH groups to form strong gels by cross-linking many polymeric materials and carbohydrates such as cellulose, starch and guar. Used as a Lewis acid catalyst in processes such as esterification, transesterification, condensation, addition, polymerizations and similar reactions. Tyzor® TEAZ is used in highly viscous thixotropic paints and waterborne paints such as acrylics.
