  • Multi-functional additive for mar and scratch resistance in chemical coating compositions
    Patent number: 11118071
    Abstract: A mar and scratch resistant additive that possesses multifunctional and other characteristics is described. The additive comprises a binder system platform that is easily introduced into a wide range of chemical coating platforms. The additive may also be introduced to these coatings by way of a silica carrier to simplify its use.
    Type: Grant

    Date of Patent: September 14, 2021
    Assignee: PISON STREAM SOLUTIONS INC.
    Inventors: Joseph H. James, Subadhra Janardhanan, Sanjana Das, Kathleen McAfee
  • Multi-purpose flexibility additive for chemical coating compositions
    Patent number: 11008474
    Abstract: A multi-functional flexibility additive that reduces surface imperfections such as orange peel, facilitates lower viscosity during endothermic reactions, provides high flexibility to the final, cured coating, and possesses chemical resistance is contemplated. The additive is formed as a binder system adhered to a resinous flow aid carrier at a preferred weight ratio of 40:60 (binder:carrier).

  • Multi-functional flow modifier for chemical coating compositions
    Patent number: 10947395
    Abstract: A multi-functional flow modifier that also serves as a wetting agent, gloss control additive, and rheology modifier is contemplated. The flow modifier itself is a mixture of polyurethane masterbatch and hydroxyl acrylic resin (free from any styrene components/resins), curatives, anti-corrosion pigments, degassers, and anti-oxidants. The flow modifier may be introduced to finished coating compositions by way of a silica carrier.
