RFP Title


Preventing Adhesion of Fine, Wet Particles
RFP Description
NineSigma, representing a Global Supplier of Industrial Elastomer Products, invites proposals for technologies that will prevent fine particulates from adhering to textured elastomeric surfaces.

Particle adhesion is a complex process involving a wide range of factors in the areas of materials engineering, particle physics, and surface and interfacial science. For industrial processing applications, these factors are further complicated by the addition of environmental influences (temperature, humidity, etc.), individual application-specific standards, and regulatory requirements. Larger particulates and clumped particles can be easily removed from the client’s engineered elastomers by in-process methods (scraping, vibration, gravitational effects, etc.). However, despite such mechanisms, microscale materials may remain attached resulting in inherent product loss, cross-contamination, reduction in process speed, system downtime for cleaning, and other issues that limit process efficiency.


NineSigma’s client has significant expertise with engineered industrial materials. However, the anti-adherent technologies investigated to date through traditional channels fail to meet their high standards for durability and operational efficacy. As such, the client has issued this open, global request to identify, develop or acquire novel technologies from across industry that can eliminate particle adhesion without the need for cleaning or offline treatments.



Key Success Criteria

The successful technology will accomplish one or more of the following:

  • Prevent adhesion (static, chemical, or otherwise) of dry and/or moist particulates
  • Facilitate release of adhered particulates by force of gravity
  • Facilitate release of adhered particulates through application of an external stimulus

Additionally, the proposed technology should address:

  • Technology must be compatible with – or adaptable to – engineered rubbers via:
    • Incorporation into a rubber matrix
    • Application to rubber as a surface treatment
  • Compatibility with fine particles / powders
    • Size: less than 10 micrometers
    • Moisture content: less than 20% 



Possible Approaches

Possible approaches might include, but are not limited to:

  • Cross-industrial approaches, including materials, processes or systems
  • Approaches that can be adapted from non-elastomeric adherence applications
  • Material solutions that migrate to the surface in response to corrosion, wear, time, etc.
  • Other materials or material engineering solutions
    • Fillers or additives for rubbers and other elastomers
    • Encapsulations, films, coatings and surface treatments
    • Anti-adherent or self-cleaning materials
    • Super hydrophobic or super hydrophilic materials
    • Materials with reversible polarity (temporary or non-permanent only)
    • Shape memory materials
    • Stimulus-activated materials
    • Self-healing materials
    • Sacrificial materials
  • Surface modifications
    • Laser treatments
    • Micro-/nano-patterning or texturizing
  • Electrically-activated technologies
    • Electroacoustics
    • Electromagnetics
    • Electrostatics
  • Nanotechnology solutions
  • Biomimetic technologies



Approaches not of Interest

The following approaches are not of interest:

  • Approaches that cannot be adapted for use with rubber materials
  • Approaches that cannot be adapted for use in moist or humid applications



Items to be Submitted

To submit a proposal, use the Respond button at the bottom of the page, which is only available when registered and logged into the NineSights Innovation Community. You may submit supplemental files in addition to your completed response form.


Appropriate responses will use the response form and address the following:

  • High level, non-confidential, description of proposed technology including:
    • Working principle or knowledge base to support your approach
    • Availability of technical data
    • Technology maturity (concept, prototype, ready to commercialize, commercialized)
  • Pathway to industrial scale including timing, estimated budget, and capacity for manufacture
  • Estimated cost of technology (if available)
  • Position on intellectual property including patent references
  • Desired relationship with sponsor
  • Team description and related experience


Other Request information includes:



Phase 1 – Proof of concept

  • Must provide trial samples and related testing results.

Phase 2 – To be determined based on scope and maturity of proposed technology


Criteria for Moving from Phase 1 to Phase 2

  • Proof of technical concept against client’s specifications
    • Technical report
    • Performance against ASTM standards
    • Samples
    • Ability to produce material at volume
  • Plan for prototyping / commercial scale-up
  • Cost analysis
  • Processing feasibility



Responses from companies (small to large), academic researchers, other research institutes, consultants, venture capitalists, entrepreneurs, or inventors are welcome. For example:


You represent an organization with a material, process or system for eliminating particulate adhesion that should provide a solution for testing in the intended application.


You represent an organization with capabilities or expertise in anti-adherent or self-cleaning technologies that can provide a solution for development and prototyping.


You represent an organization with technology that should provide a solution but that requires further research and development to ready it for transfer to commercial use.
