The Seeker is looking for a novel defoamer formulation or technology for use in glossy water-based paints with low pigment volume concentration (PVC). The solution must effectively prevent or destroy foam, be silicone and mineral-oil free, and not cause surface defects in the finished coating.
This is a Reduction to Practice Challenge that requires written documentation, experimental proof-of-concept data, and sample delivery if requested by the Seeker.
Defoamers are necessary additives to paints in order to curtail the development of unwanted foams. However, while defoamers can effectively inhibit or destroy foams they may also leave undesirable surface defects. Although defoamers currently used by the Seeker are applicable to matte and low-gloss paints with  medium and high pigment volume concentrations (PVC)  they are not suitable for glossy coatings which have low PVC because they introduce noticeable surface defects and thus affect the glossy finish. Therefore, the Seeker is looking for a novel defoamer formulation or technology for use in water-based paints with low pigment volume concentration (PVC). The desired solution must be able to effectively prevent or destroy foams and not introduce noticeable surface defects in the finished coating.
The submission to the Challenge should include the following:
- A detailed description of the proposed Solution addressing specific Technical Requirements presented in the Detailed Description of the Challenge. This description should be accompanied by a well-articulated rationale supported by literature/patent precedents.
- Experimental proof-of-concept data obtained and presented as outlined in the Challenge (and/or delivery of proposed material if requested by the Seeker).
The Challenge award is contingent upon theoretical evaluation and experimental validation of the submitted Solutions by the Seeker.
