- Addition and Dosage
The optimal amount of PAT-ADD AF 35 to be used is system related, but generally is between 0.1 and 0.3 % PAT-ADD AF 35, calculated on the total weight of formulation. Appropriate incorporation conditions have to be provided, in order to minimize risk of paint film surface defects. Required incorporation conditions are related to system characteristics, such as viscosity, dispersion and solubility characteristics. Standard let-down conditions (mixer) may be considered in systems, which contribute to proper dispersion of PAT-ADD AF 35.The optimum concentration to be used depends on the individual requirements and conditions.
- HIGHLIGHTS
Outperforming de-aeration properties in waterborne industrial paints; Beats formation of micro-foaming; Extremely efficient, requires just low dosages; Effective over a wide pH range
- End Use Applications
PAT-ADD AF 35 is liquid defoamer for use in pigment concentrates and industrial coatings, such as water reducible systems, systems based on polar solvents or high-polarity solvent-free systems. Typical application areas are in pigment concentrates and universal colorants, waterborne industrial topcoats, as well as in solvent-free systems such as PU- or EP based floorings.
- Storage and Packaging
The product may separate or settled upon storage so best to mix it well before use.; Drum : 200 kgs., Can : 25 kgs.
