Cameo Agent BBM and BBWK are polyacrylate which may be used to produce hammer tone powder coatings. BBWK distinguishes itself from BBM by producing more uneven surface.
BBM and BBWK donnot contain any silicons.

APPLICATION
Both BBM and BBWK can be applied in Epoxy, Hybrid and Polyester powder coatings systems, and they must be dry blended with the coatings. The appearance of surface is relevant to the dosage and particle size of agents, and the dosage of agents is generally 0.1~2wt% of the whole formulation
