Luna-pal A81 is a polyaldehyde resin produced by condensation of urea aliphatic aldehydes with a softening range between 80-90°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.

Luna-pal A91-K is a versatile polyaldehyde resin - condensated from urea aliphatic aldehydes - ideal for pigment pastes and industrial coatings with a softening range between 90-100°C.
