PAT-ADD AF 29 is dispersible in aqueous systems and can be incorporated (depending on dispersion power characteristics of the applied system) by applying mild to high shear dispersion forces. PAT-ADD AF 29 is most suitable for use in dispersion paints, high PVC to low PVC qualities.
- Benefits
- Free of mineral or synthetic oil
- Meeting regulations for oil-free materials
- Direct replacement for oil-based defoamers
- Requires only low dosages; does not contribute to VOC
- Clear liquid, showing excellent shelf stability
Applications & Uses
- Markets
- Use Level
- 0.1 and 0.8 %
- Application
Oil free defoamer for best transparency in flexo inks, varnishes
- Dosage & Addition
The optimal amount of PAT-ADD AF 29 to be used is system related, but generally is between 0.1 and 0.8 % PAT-ADD AF 29, as calculated on the total weight of paint formulation. The optimal dosage is best found by a ladderized study. Typically lower or max.same levels are being used in exchanging oily defoamers. Proper incorporation by mild to high shear mixing is prefered, in order to ensure required distribution and minimize risk of film defects. Prefered is addition of half the amount, prior to pigment milling and remaining part to the mill-base before the letdown step of paint manufacturing. The optimum concentration to be used depends on the individual requirements and conditions and is best determined experimentally
