Microbloc® DSP is a ready to use formula. Microbloc® DSP is a water-stabilized, quat-functional reactive siloxane that creates a clear barrier on both porous and non-porous surfaces that effectively inhibits staining, discoloration, deterioration and odors that are typically associated with mold, mildew, fungi, algae, bacteria, yeast, virus, germs and protozoa. This water-based product should be used “as is” and eliminates the hazards of conventional methanol-based additives and heavy metal treatments. For a general description of the typical chemical and physical properties refer to the Material Safety and Data Sheet.
