Polyaldehyde resin produced by condensation of urea aliphatic aldehydes with a softening range between 90-100 °C.

SETAL AF 681 TB is in the formulation of decorative paints with excellent through-drying and good yellowing resistance. Also for flow coatings, DIY paints and air-drying coatings. General Setal A F 681 TB is a low-viscosity long-oil alkyd resin which is ideal for use in the formulation of DIY and decorative paints with excellent through-drying, a dust-free drying time of approx. 3.5 hours and a tack-free drying time of approx. 6 hours. Because of the relatively high acid value of Setal A F 681 TB, the following driers should be used: 0.04 % cobalt 6, 1.20 % zirconium 18 and 0.20 % calcium 4. The metal content is always calculated on the solvent-free resin. The use of these driers ensures good drying stability, even after prolonged storage. The addition of an anti-skinning agent is recommended. Aliphatic hydrocarbons are used to thin Setal A F 681 TBA. Higher boiling fractions are particularly suitable for adjusting the brushing viscosity. Standard pigments can be used to colour the formulations. The compatibility with alkaline pigments must always be tested in each individual case.

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.

SETAL D RD-181-MPA is the co-reactant for Desmodur HL, IL, L and N in the formulation of twocomponent PU coatings. SETAL D RD 181 MPA is used in the formulation of coatings for wood, e.g. boats and parquet flooring.
