Defoaming agent PD885,PD996,P498 are used for construction materials processing, grouting material,mortar,cement,concrete,puttypowder,powder coating, asbestos shingle,calcium silicate board ,plasterboard ,vinylon cement pipe etc.

　　During the processing of cement mortar ,various additives and high speed mixing will lead to serious foam problem. The bubbles will lead to the production of cement mortar products not smooth with honeycomb, pits and other phenomena, which will seriously affect the appearance. Our defoamers can be directly added in the manufacturing process ,it can eleminate bubbles quickly with sustaining anti foam capability.

　　Defoamer powder PD885 as a silicone based antifoam powder,specially designed for construction materials like Cement Grout, Self leveling cement etc.

　　Antifoam powder PD996 it is composed of modified polysiloxane, polyether, carrier and other compounding ingredients. It offer quick bubble break performance, excellent foam suppressing,widely used in construction materials like grouting material,mortar,cement,concrete,puttypowder,powder coating etc.

　　Polyether antifoam agent P498 is a kind of polyether defoamer, suitable for both building chemical additives and building materials.
