Polyaldehyde resin produced by condensation of urea aliphatic aldehydes with a softening range between 80-90 °C.

Luna-pal K80 is a highly light-fast, rigid resin with light color. It is soluble in most solvents used in the coating industry, excluding aliphatic hydrocarbons and water. It is compatible with many resin materials used in paint and ink. Luna-pal K80 can improve the gloss, adhesion, pigment wetting, film hardness and solid content, and reduce the overall viscosity. When used in adhesives, it can improve the initial adhesion, and especially improve the lasting adhesion. Softening point: 75-95°C.

Luna-pal KY-A81-C (Benzene Free) is a polyaldehyde resin for pigment dispersions, or to optimize pigment dispersion in inks and coatings. It shows excellent compatibility with many coating/printing raw materials. It is soluble in most organic solvents and has very good wetting and dispersion properties. It is a multifunctional additive used also to improve the adhesion, gloss, hardness, and solid content. It can also be used in universal pigment pastes.Softening point: 90-100°C.

SETAL A F 681 TBA 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 TBA is 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 TBA, the following driers should be used: 0.04 % colbalt 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
