Aldehyde resin is defined by the condensation reaction of aldehydes and ketones into polymer, also known as aldehyde ketone or ketone resin. In general, the keto aldehyde resin modified molecular structure containing carbonyl, hydroxyl groups in the end, resin and solvent and coating has good compatibility, good wetting of pigment dispersion effect, can effectively improve the adhesion, gloss and hardness of coatings, is a multifunctional coating for a the excellent performance of the additives, widely used as grinding resin coating, ink and coating properties of general paste additives to enhance Ketone aldehyde resin used for wood paint, composite, flexographic, gravure ink, ink pen, ink, alcohol containing bronzing material, heat sealing coatings, high solid coatings industry. Uses: Applicable to the majority of ink, paint and adhesive system, used to improve the ink, paint and adhesive film and fast drying, gloss, adhesion, mobility, pigment wettability and solid content, etc., is the ink, paint and adhesive. Performance: Features such as gloss, hardness, resistance to degradation, in the sun does not change color, etc. Ideal solubility and compatibility, as well as having good pigment wetting and adhesion Since there is no ester bond in the structure of the aldehyde ketone resin, it has good water resistance.
