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.
|Solvent-borne coatings||Aqueous coatings|
These additives can be added during any production process, including post-addition.
|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.
