TUNGOPHEN® B NV is applied as an additive in alkyd coatings. Additions of 1 - 3% TUNGOPHEN® B NV, calculated on the 100% alkyd resin, greatly accelerate the through-drying and increase the gloss of alkyd coatings. Initial drying slows in proportion to the addition of TUNGOPHEN® B NV. This improves the flow properties of the coating and reduces the likelihood of surface defects, even in thicker films. TUNGOPHEN® B NV is usually added at room temperature as a solution in xylene. The addition of TUNGOPHEN® B NV results in yellowing. For this reason, it should not be used in white coatings. The amount used in pale-colored coatings should be kept to a minimum. Addition of the product to coatings based on medium-oil alkyd resins, e.g. Setal A F 48, will result in particularly significant acceleration of through-drying. TUNGOPHEN® B NV should not be used in styrenated alkyd resins, oil based coatings or oil/resin combination coatings.
