  (1) Coating industry 

a. Product features and advantages

The additive combines high efficiency and good compatibility in a variety of systems and applications. Excellent long-term stability at high and low temperatures. Effective in both pigmented and clearcoat systems, suitable for all gloss levels and common systems. Due to its good compatibility, this additive has only a slight tendency to cause surface defects (shrinkage craters, haze) and is easy to add. BYK-093 can be used in combination with other defoamers for zero and low VOC coating systems containing solvent-free resins.

b. Recommended use

Architectural coatings, wood and furniture coatings, industrial coatings, can coatings, coil coatings, leather finishes

c. Recommended dosage

0.3-1% Auxiliary dosage (as purchased) is based on the total formulation. In certain cases up to 1.5 %.

d. Joining methods and processing instructions

The additive can be added at any point during production. Only low shear force is required for addition, and can also be added as a post-additive.

(2) Adhesive & Sealant

a. Product features and advantages
