One of the most necessary constituent in powder coatings is the flow control agents (FCA). Its mechanism is to have a liquid compound once the powder particles are melting, incompatible with the binder. Therefore it will migrate to the surface of the particles and behave as a coalescent agent.<\/p>\r\n

Flow control agents (FCA) for powder coatings are often liquid acrylic polymers adsorbed on porous carrier materials like silica. Nontheless, when one uses a solid FCA, only 67% of the product is active, the rest being silica most of the time. This silica has a cost and is ineffective. Thus, powder coating formulators can only empirically calculate how much of the adsorbed FCA will really participate to the flow of the powder particles.<\/p>\r\nPudraflow, flow control agent masterbatches<\/strong>\r\n

Pudraflow masterbatches contain no silicone<\/strong> and are available in 15% active additive substance formulated in either carboxyl <\/strong>or hydroxyl <\/strong>polyester resin. Pudraflow based powder coatings can result in excellent flow and superior levelling characteristics, eliminating surface defects like orange peel, craters and pinholes and improving cross-compatibility between different systems.<\/p>\r\n\"\"\r\n\r\nCore Benefits!<\/strong>\r\n
