Pat-Add AF 34
- CASE Ingredients Features
- Long Shelf Life
PAT-ADD AF 34 is liquid defoamer for use in waterborne coatings like varnishes, wood-coatings, industrial paints, aqueous inks and pigment dispersions.PAT-ADD AF 34 is oil and VOC-free and based on a polysiloxane hydrophobic polymer compound.PAT-ADD AF 34 is versatile in application, so efficient in various waterborne systems such as dispersion paints, industrial systems, inks and adhesives. It is effective fordefoaming and anti-foaming purposes during manufacturing and application and reduces risk of micro-foaming.

- Properties
PAT-ADD AF 34 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 34 is most suitable for use in dispersion paints and industrial paint systems; furthermore for flexo inks as well as for use in pigment dispersions.
- Application
Incorporated with medium to high shear dispersion forces. Most suitable for industrial paint, flexo inks as well as for use in pigment dispersions.. Most suitable for flexo inks as well as for use in pigment dispersions.Incorporated with medium to high shear dispersion forces.

- Addition and Dosage
The optimal amount of PAT-ADD AF 34 to be used is system related, but generally is between 0,08 and 0,8 % PAT-ADD AF 34, calculated on the total weight of formulation.Proper incorporation by mild to high shear mixing is prefered, in order to ensure proper distribution and minimize risk of film defects. For pigment dispersions, dosages up to 1 % may be required. It is recommended to add part of the required dosage prior to pigment grinding and the remaining part to the mill-base before the let-down step of paint manufacturing. The optimum concentration to be used depends on the individual requirements and conditions and is best determined experimentally.
