SILFOAM^® SD 670

Application

Basically, SILFOAM® SD 670 is recommended for all organic systems that require a highly compatible antifoam agent. Thus, it is ideal for applications in which silicones would usually cause problems, e. g., printing inks, adhesives, and water miscible cooling lubricants.

It is particularly recommended for systems with a high surfactant content or which entail high shear forces, e. g., the incorporation of pigments into dispersions. In those systems purely organic defoamers rapidly become ineffective.

SILFOAM® SD 670 also serves as an antifoam agent for strongly foaming, fine particle rich suspensions and in the production of redispersible powders.

Processing

The exact dosage must be determined in preliminary tests. We recommend starting with amounts between 0.05% and 0.3%.

Generally, the product should be added as it is, as its self-dispersing properties will usually ensure an adequate and homogeneous distribution.

If SILFOAM® SD 670 is diluted with water, the resultant dispersion must be used quickly.
