These properties are provided as typical properties. NOT THE PRODUCTS TECHNICAL INDEX.

Proposed Dosages:

Dosage based upon inorganic pigments, %
IR-8230.05-0.6
The above-recommended dosages strongly depend on pigment particle size. Optimal dosages should be calculated in the laboratory according to a different formula.

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-823Recommended

Addition Methods&Process Technology Instructions:

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

Special Features:

IR-823– IR-823 defoaming effect (i.e., no or only slight foam stabilization) depends on the polarity of the paint system. It is heat resistant up to 250°C and does not decrease inter-coat adhesion when overcoated.
– Inwood and furniture coatings, IR-823 is used to orient the flatting agent in flat topcoats and in multi-coat systems.
– IR-823 cannot increase shine even in polyurethane, acid curing, and unsaturated polyester coatings, then the optimal orientation of the flatting agent can be achieved.
– Inflow coat systems, IR-823 provides a stable curtain.
– In industrial coatings, IR-823 supports the orientation of flatting agents and aluminum flakes in metallics paints.

Packing:

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