ADDITOL VXW 4973 is an easily emulsifiable defoamer with very good incorporating ability. It is suited for defoaming of coarse-disperse to fine-disperse (plastic) dispersions on the basis of PVAC, PVC, acrylates and their copolymerisates. Also low-viscous products may be defoamed with ADDITOL VXW 4973.

ADDITOL XL 121 is a paint additive to enhance mar resistance and levelling of air drying and stoving paints, particularly for silicone modified air drying and stoving alkyd resins. ADDITOL XL 121 is a silicone containing paint additive supplied as low-viscous solution. ADDITOL XL 121 enhances mar resistance of solvent-borne paints by reducing the surface resistance of the paint film. ADDITOL XL 121 improves levelling and prevents film structures and thus enhances film performance in general. ADDITOL XL 121 is suited for air drying alkyds, stoving alkyds, thermosetting acrylic resins, nitrocellulose paints, acid curing paints, alkyd-acrylate-isocyanate systems, and particularly for air drying and stoving-silicone modified alkyd resins. The effect of ADDITOL XL 121 depends on the type of paint system and on the formulation. The quantity of ADDITOL XL 121 may range from 0.1 - 0.5 % on paint as a guide.

SETAL A U 601 TB is in the formulation of hard-wearing wood finishes, parquet sealers, fast-drying synthetic resin coatings and industrial primer surfacers. General SETAL A U 601 TB is an isocyanate-modified alkyd resin which is especially suitable for the formulation of fast-drying, colourless or pigmented, DIY and decorative paints. The paint films have high mechanical strength, hardness and long-term flexibility. They also have good resistance to water, household cleaning agents and many chemicals. The use of the following driers is recommended: 0.03 - 0.04 % cobalt 6, 0.60 - 1.00 % zirconium 18 and 0.05 - 0.15 % calcium 4. The metal content is always calculated on the solvent-free resin. Methylethyl ketoxime has proved ideal as an anti-skinning agent for these formulations. The amount required is 0.7 - 1.3 %, calculated on the solventfree binder. SETAL A U 601 TB can be thinned with the usual solvents. Aliphatic hydrocarbons with small amounts of aromatic and terpene hydrocarbons are especially suitable. Wood finishes: Rapid drying, excellent filmhardness, high abrasion resistance and good longterm flexibility make SETAL A U 601 TB ideal for the formulation of parquet sealers, finishes for chairs and benches, coatings forwindowframes and other coatings for indoor and outdoor use. Because of the good water resistance of coatings based on SETAL A U 601 TB, they are also suitable for use as marine paints. Clear coats based on SETAL A U 601 TB can be matted with standard matting agents. In order to prevent the settling ofmineralmatting agents, the addition of small amounts of SETAL A U 601 TIX TBA is recommended. SETAL A U 601 TB has good compatibility with long-oil alkyd resins, e.g. SETAL A F 681. Combination with such resins increases the solids content and thus the potential dry film thickness of the coatings. 4 : 1 combinations of SETAL A U 601 TB and A F 681 can still be matted well. Coatings based on SETAL A U 601 TB dry to form defect-free films on most Tropical woods so no special impregnation is necessary before hand. However, given the many different types of tropical woods and their very different properties, trials should always be carried out.

Prevents the sedimentation of pigments in paints. Improves the pigment-wetting during dispersion. In many paint systems the floating of pigments in pigment-mixtures is prevented. The tendency to flow off is reduced and the covering of edges is improved. Suggested for all solvent based and solvent-free paint systems. ADDITOL XL 270 is usually compatible with solvent based and solvent-free binders. It prevents the sedimentation of pigments in paints. The rheological character of paints is improved. The tendency to flow on vertical surfaces is reduced. The edges of substrates are better covered in case of dipping application. The drying of oxidatively drying systems is not influenced by ADDITOL XL 270, if the appropriated dose is used. Also the efficiency of siccatives in paints, stored for a long time, is not reduced using ADDITOL XL 270. Considering anti-corrosive paints, there is no corrosion-resistance loss by using ADDITOL XL 270. It is recommended to be used for the activating of organophile bentonites and it improves the effect of pyrogene silica.
