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 PTSI-P is used in the formulation of polyurethane products as a reactive additive with low viscosity. Luna PTSI-P prevents moisture related problems by reacting with trace moisture. Excess water reacts with Luna PTSI-P towards the corresponding carbamic acid, which undergoes immediate decomposition to form carbon dioxide and the relatively inert p- toluenesulfonamide, which is commonly used as a plasticizer.

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.
