Proposed Dosages:

Dosage based upon inorganic pigments, %
IR-8250.01-0.4

Functions:

These additives provide a slight reduction in surface tension of paint systems, which thus improve flow and leveling and display partial defoaming properties. Additionally, they prevent “Bénard Cell” formation.

Uses:

Solvent-borne coatingsAqueous coatings
IR-825RecommendedSuitable

Addition Methods&Process Technology Instructions:

These additives can be added during any production process, including post-addition.

Special Features:

IR-825IR-825 prevents ghosting (wipe-marks) if recoated with the same paint. It neither causes rewetting problems nor influences recoatability.

Packing:

Packed in iron drums of 25 or 200kg net each. The validity period is 12 months in sealed containers.
