Multi-functional silizane-based coatings and materials

Abstract

The present application is directed to a multifunctional coating for operation at temperatures in excess of 150° C., and up to 300+° C. The multifunctional coating includes: a) one or more polysilazanes (i.e., a group of silicon-based polymers) that include inorganic and/or organic functionalized polysilazane; b) one or more secondary polymeric additives one or more secondary polymeric additives (e.g., siloxane compounds and/or polysilane compounds); c) one or more optional functionalized nanoparticles and/or fillers; d) one or more optional additive polymers that include: i) Polysulfones (PSF) such as Polyethersulfone (PES) and/or Polyphenylene sulfide (PPS); ii) Polyimides (PI); iii) Polybenzimidazole (PBI); iv) Polybenzoxazoles (PBO); and/or v) fluoropolymers including Polytetrafluoroethylene (PTFE), Polyvinylidene fluoride or polyvinylidene difluoride (PVDF), Fluorinated ethylene propylene (FEP), and/or hexafluoropropylene (HFP); e) one or more optional additives (e.g., biocide, foaming agent, surface tension agent, pigment, curing agent, surface friction reducing agent, stabilizers, flexibilizers, inhibitors, flow control agents, anti-oxidants, degassing agents, dyes, coupling agent, dispersing agents, catalyst and/or hardeners; etc.); and f) one or more optional solvents; and which multifunctional coating is formulated such that it can optionally i) function as a high-temperature insulator, ii) have high elongation and/or improved hydrolytic stability, iii) have extreme weather resistance, iv) have high chemical resistance, v) have high impact and/or abrasion resistance, and/or vi) have improved thermal cycling resistance.
