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.

ADDITOL VXW 4940N is the lead-free combination drier. ADDITOL VXW 4940N produces in water-dilutable alkyd resin paints a quick set-drying in connection with an even trough-drying. ADDITOL VXW 4940N contains all metals which are necessary for an utmost oxidative drying. Adding any other drier is not necessary. The lead-free combination drier ADDITOL VXW 4940N produces in water-dilutable alkyd resin paints a quick set-drying in connection with an even trough-drying. ADDITOL VXW 4940N contains all metals which are necessary for an utmost oxidative drying. Adding any other drier is not necessary. ADDITOL VXW 4940N can be used as drier for all water-dilutable, oxidatively drying alkyd resin paints. Especially recommendable is the usage of ADDITOL VXW 4940N for drying alkyd resin emulsions, e. g. Resydrol AY 586w, Resydrol AY 466w, Resydrol AZ 436w, because contrary to conventional driers a homogeneous distribution is provided and therefore a quick drying and most of all good drying stability can be achieved. ADDITOL VXW 4940N can also be used for acryl-alkyd hybrid systems.

SETAL A F 26 X is in the formulation of primers, knifing fillers, primer surfacers, top coats and dipping paints and flow coatings for radiators. Coatings based on SETAL A F 26 X are characterised by their very rapid drying and curing, high resistance to yellowing, weather stability and good anticorrosion properties. The use of alkaline pigments such as zinc phosphate, zinc oxide and aluminium triphosphate make it possible to optimize the anticorrosion properties of primers based on SETAL A F 26 X. Knifing fillers and primer surfacers applied in thickness of up to 200 μm can be dry-sanded within 1 hour. Combination with aminoplastic resins is recommended when formulating force-drying coatings.
