Organically modified polyalkyl polysiloxane AFCONA –2280 is a very effective defoamer and air-releaser for solvent-based and solvent-lesssystems. AFCONA –2280is a silicone-based product developed to produce rapid de-aeration for pigmented and mat finish of wood coatingin NC,AC and PU.For high gloss and transparent wood coating,It may cause some in can haziness when the dosage ishigher than 0.50% in PU and AC system. It’s also suitable for polyurethane and epoxy compounds used in flooring or general industrial application.AFCONA –2280also acts as a very good levelling agent,giving a smooth surface to the coating.It functions differently from AFCONA 2722 asthe siliconecontent is higher and the real active ingredient as defoamer is also higher.

Organically modified Polysiloxane Water based defoamer and anti-foam, especially for micro foams AFCONA-2505 is an organically modified polysiloxane which designed to give good defoamer and anti-foam in all water based coating. It has excellent performance against micro foam.AFCONA –2505 have below performance and properties:1)It has very good performance in high shear application. Under high shear environment such as long period of grinding, it still can maintain it good defoaming and anti-foam performance. Thus verysuitable to use as defoamer in pigment concentration preparation and high speed flexo printing process.2)It also effective as defoamer in normally coating ranging from PU dispersion to normal acrylic based decorativepaint.3)Beside good defoaming and anti-foam properties, it also has excellent performance against microfoams.4)It has low sensitivity against crater formation.
