RFP Title
Moisture Tolerant Coatings
RFP Description

NineSigma, representing a Global Consumer Coatings Company, invites proposals for technology approaches that allow an architectural coating to be effectively applied to a damp surface without affecting the protective properties of the cured coating. The desired resulting technology will be as effective as current high-performing architectural coatings approaches, but will allow for the application onto a damp surface without additional pre-treatment.


Exterior architectural surfaces, such as wooden siding and deck boards, need to be protected from the elements by regular applications of protective coatings. For maximum protection against rain, UV, and other weathering elements, the coating application process must be followed exactly, and often requires ideal conditions. Historically, paints and coatings require a dry surface for effective adhesion and proper curing (no more than 20%-30% moisture content on the surface).


Surfaces that are damp to the touch (from exposure to rain, dew, humidity, and shade, for example) typically will not allow for the effective application of a protective coating as compared to application to a dry surface. The coating, if applied to the damp floor or wall surface, will not adhere evenly, and the moisture in the substrate will affect the curing (drying) time of the coating.


The RFP sponsor is seeking technology approaches (materials, process, and chemical innovations) that would eliminate having to wait for perfect conditions before a coating can be applied to an exterior surface, while maintaining the performance of the exterior coating. The current recommendation for application of an exterior coating is for surfaces that are under 20% - 30% moisture content. This RFP seeks approaches that can improve upon this moisture range. Ideally, the resulting coating will be able to be applied to both dry and damp surfaces, and/or incorporate the water from the surface in a curing mechanism. 



Key Success Criteria

The successful technology will:

  • Allow for a coating to adhere to a damp surface, without any pre-treatment
  • Allow for application over surfaces that have moisture content greater than 30% (i.e. freshly-washed decking surfaces)
  • Not contain isocyanates or other toxic compounds
  • Prefer compliance with California environmental regulations including volatile organic compounds content
  • Allow for a consumer-friendly, non-toxic coating product
  • Not require any special personal protective equipment during application.
  • Be applicable to any exterior architectural surface (wood, concrete), as well as surface orientation (horizontal, vertical), whether or not the surface was previously treated
  • Perform as well as a good quality exterior paint or stain, in terms of durability, protection, etc.
  • Be at least as effective as current protective coatings that are applied to dry surfaces, in terms of durability and protective performance (UV, mold/mildew, etc.)
  • Be applied to the intended surface using a brush or roller (i.e. typical equipment that a consumer would use)
  • Ideally, the proposed system would be applicable to both wet or dry surfaces





Possible Approaches

Possible approaches might include, but are not limited to:

  • Adhesives, adhesion approaches
  • Materials with water curing properties
  • Nanomaterials, polymer systems, advanced materials
  • Formulations, components, or additives (for water-based formulations) are all of interest
  • Technologies that are currently used in other industries and applications that can be adapted for exterior coatings for consumer use



Approaches not of interest

The following approaches are not of interest:

  • Any potential solution that requires exotic materials, or materials that cannot be sourced sustainably
  • Approaches that cannot meet standard VOC requirements for consumer goods or that contain isocyanates
  • The RFP sponsor is not interest in consulting agreements at this time. All proposed approaches must be at least demonstrated at lab scale to be considered for this RFP.
