Outline:

  • Overview of “FEVE” resin technology

  • Introduction of water-based “FEVE” emulsions

FEVE Fluoropolymer Resins

  • “FEVE” is abbreviation for “Fluoroethylene Vinyl Ether” resins for coatings

  • Known for their high performance properties:

  • Exceptional resistance to UV degradation

  • Superior Chemical Resistance

  • Excellent Thermal Resistance

    - Known for their unique formulation properties:

    1) Solvent soluble

    2) Can be cured at ambient temperature with isocyanates

    3) Can achieve high gloss formulations


Fluoroethylene vinyl ether feve resins

FLUORINATED SEGMENTS: Weatherability, durability, chemical resistance

VINYL ETHER SEGMENTS: Gloss, solubility, crosslinking

Commercial Types of “FEVE” Resins:

  • Solvent soluble resins –

    uses organic solvents for viscosity reduction;

    predominantly cured with isocyanates; available as

    resin solutions or as 100% solid resins

    2) Water-based emulsions –

    use vinyl ether macromonomers containing

    polyoxyethylene (EO) units to create stable emulsions

Testing procedure # 1 :

1) Choose 3 different acrylic emulsions from 2 manufacturers as blending resins for White DTM I/M Formulation. Blend these acrylic emulsions with the FE emulsions and run oven stability tests.

2) Manufacture of 2 White DTM I/M Paint formulations:

Conclusion:

Inclusion of FEVE emulsions in architectural coating formulations can increase gloss retention, color retention, and the overall durability of the dry film. These characteristics will prolong the aesthetic properties and the protection properties of these coatings, thereby increasing the time frame between recoats.
