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.

MODAFLOW LAMBDA is a unique acryl-silicone polymer hybrid technology flow promoter combining individual efficiencies from high end acrylic as well as silicone leveling performance. It is highly compatible in all non-aqueous clear coat and topcoat formulations and outperforms surface characteristics such as: gloss, DOI, sharpness & brilliancy, anti orange-peel effect. It is efficient at low dosage levels and incorporates easily in many solvent borne resin types including high solids and ultra-high solids. Further it can be applied in solvent free and radiation curing systems.MODAFLOW LAMBDA demonstrates superior balance of compatibility and effectiveness compared to traditional silicone or acrylic flow and leveling additives in Automotive OEM, refinish as well as industrial coatings. Due to its high hydroxyl functionality, MODAFLOW LAMBDA may be co cross-linked in stoving or 2K systems and does not show a decrease in interlayer adhesion. In multiple layer systems the stoving temperature should not exceed 130 °C to ensure a good recoatability. The recommended dosage level is 0.05 % calculated on total formulated coatings as a starting point and optimum dosage range is between 0.05 % - 0.3 %. In some cases the dosage could be increased up to 0,5 %.

MODAFLOW 2100 is a flow modifier developed for high performance polyester and acrylic based, high solids and UV liquid coating applications. Modaflow 2100 contains no silicone ingredients. The addition of Modaflow 2100 will help: improve flow and levelling, reduce pinholes, fisheyes, craters, and orange peel, improve substrate wetting, aid in air release, facilitate pigment dispersion, quantity to be added: 0.1 - 1.0 % on solid resin.

PC-1644 DEFOAMER is a 40 % solution of an acrylic polymer in a petroleum solvent. It was developed to offer improved defoaming performance versus PC-1244 in non-aqueous organic fluids. PC-1644 is a general purpose defoamer which offers superior foam control at low use levels, generally 10 to 20 % lower use level versus PC-1244. PC-1644 is silicone-free and exhibits very low odor. PC-1644 defoamer applications include usage in gear oils, specialty lubricants, and shock absorber, hydraulic, turbine or transmission oils. Typical use levels of the solutions range from 50 - 500 ppm (20 - 200 ppm active polymer). The optimum level is dependent upon the nature of the oil and it is therefore necessary to run a concentration profile for each oil. The defoamer is most typically employed at 200 - 250 ppm of solution (80 - 100 ppm active polymer).
