Lacper® 4218

Lacper® 4218 is an aliphatic polyurethane dispersion, it is specially developed for low odor waterborne wood coating. It has low odor both in wet film and dry film, At the same time, It has good wetting ability on wood substrate, also has good film building, film clarity and wood warming effect. It is recommended to be used in the preparation of water-based 1K wood coating, and can also be used in combination with water-based curing agent to prepare low odor water-based 2K wood coating. The product contains no solvent, APEO and Organotin. Less than 1% DMEA is used as neutralizing agent. Bactericide: CMIT: MIT=3:1 14ppm, BIT: 200ppm.
