ADDITOL VXL 4930 may be used in all solvent-containing and water-dilutable paint systems. It promotes the spray dust absorption, prevents orange peel and increases scratch resistance. ADDITOL VXL 4930 is effective at low concentrations and at the correct dosage, does not adversely affect intercoat adhesion. Blistering, cratering and floating in pigment blends are effectively prevented. It does not stabilize the foam during paint production and application. The substrate wetting is advanced.ADDITOL VXL 4930 is used primarily in industrial stoving/baking paints and 2K PUR paint systems.

ADDITOL VXW 6393 was designed to destroy foam generated in emulsion wall-paints, based on PVAC, PVC, acrylics and their mixed polymers. Prior to using ADDITOL VXW 6393 it should be thoroughly agitated since it is prone to sediment fall out. When examining its rheology it is necessary to wait an additional 5 minutes. ADDITOL VXW 6393 can be easily emulsified and worked into the designated product.

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.

ADDITOL XW 395 Enhances surface properties of the films and prevents film defects like insufficient wetting and structured surfaces owing to impurities. ADDITOL XW 395 is an additive specially designed for Resydrol paint systems and, compatibility provided, for other waterborne paint systems. Considering the levels and restrictions given below ADDITOL XW 395 can be used in any water dilutable paint with the exception of electrodeposition paints. ADDITOL XW 395 prevents film defects, such as craters and pin holes or can remedy poor wetting owing to impurities brought into the aqueous paint during preperation or processing. Insufficiently degreased metal is the main cause for such troubles. With ADDITOL XW 395 wetting problems are avoided. It should be noted that film defects arising from silicone oils in many cases cannot be prevented with ADDITOL XW 395. ADDITOL XW 395 prevents floating of pigments, striation, orange peel, etc. and improves the film surface in general. ADDITOL XW 395 at the recommended levels, does not impair the physical properties of the stoved film. In primers ADDITOL XW 395 may cause a certain degree of gloss. Additions of ADDITOL XW 395 may adversely influence the effect of antifoaming agents; on the other hand, it can remedy infavourable effects of the antifoams. In aqueous paints for spray application ADDITOL XW 395 can be used without precautions, while in dipping or flow coating paints ADDITOL XW 395 must be carefully balanced with the antifoams normally present.
