QA AQUOLIN 268 is water dispersible HDI isocyanate, used as curing agents for areas such as textiles, adhesives and industrial coatings, and can also be used as additives to improve the performance of waterborne coatings.

THIXATROL® ST rheological additive is a modified derivative of castor oil for use in aliphatic and aromatic solvent-borne coatings. It also imparts flow and levelling control to powder coatings.

High pigment loading without increase in viscosity. Reduction of dispersing time. Enhances gloss and levelling. For air drying and stoving solvent-borne paints and particularly for water dilutable paint systems. ADDITOL XL 203 prevents the floating of titanium dioxide in conjunction with organic or inorganic coloured pigments. It can be employed in solvent-borne and water dilutable air drying and stoving paint systems. ADDITOL XL 203 enhances gloss and levelling of paint films. Pigment loading of paints and pigment pastes can be increased without rises in viscosity. Dispersion time is reduced. The recommended level may range from 0.1 to 1.5 % on total paint. Level on pigments: inorganic pigments: 0.5 - 2.5 %, organic pigments: 1.5 - 5 %. The figures given here may serve as a guide for extensive trials to find the optimum in dosage and effect and to save costs. Since ADDITOL XL 203 is a cationic product it should not be used in conjunction with certain anionic products. Phase seperation occurs and ADDITOL XL 203 becomes ineffective at once. The compatibility should be determined by experiments. ADDITOL XL 203 can be combined with cationic and non-ionic products.

ADDITOL XL 6568 is used for the formulation of stripping enamels, release agents and temporary corrosion protection. ADDITOL XL 6568 is added to stripping enamels as anti adhesion promotor. Coatings of this nature give temporary protection against mechanical attack and corrosion to various substrates. Such coatings can easily be pealed off later. ADDITOL XL 6568 can be used in solvent based as well as in aqueous systems. Suitable binders for solvent based systems are the Hostaflex grades CM 150 and CM 133 as well as the Mowital grades B30HH and B60H. To formulate aqueous systems, acrylic dispersions like Ucecryl B 3022 are recommended. While solvent based release coatings can easily be removed from metallic substrates aqueous systems based on styrene acrylate dispersions can also be removed from glass, pottery, wood and plastics. For formulating systems with high film strength aqueous systems are more suitable than solvent based systems.
