HTP-100 spray cans are now available for purchase here! Spray cans are intended for rapid coating trials on your substrate of choice and can also be used in service for specialty applications, such as sealing of a weld or braze.

The unique coating microstructure and chemistry of HTP-100 significantly differentiates its performance from its competition: 

  • Hermetic quality diffusion barrier at substrate/coating formed in situ
  • Toughness and thermal stability based on low modulus design and stable chemistry

Hot Corrosion Protection

  • Inert in most industrial high temperature service environments (up to 1800 °F)
  • Hermetic ultra-thin interfacial layer formed in situ seals and protects substrates in oxidizing, reducing, or vacuum environments
  • No observable oxide scale for low-grade ferritic stainless steel after 1800 °F exposure in humid air
  • Enables replacement of advanced alloys with lower grade counterparts (AUS 304 vs AUS 310)
  • Protects welds and brazes from galvanic corrosion in thermal cycling service
  • Seals porous refractories and composites
  • Stable against non-ferrous molten metal and molten salts to 1800 °F

One Coating For Any Alloy or Ceramic

Easy to Apply

  • 3 easy steps - spray, dry, and cure in an oven
  • Rapid drying and thermal curing for efficiency in production
  • Strong chemical bonding with substrate enabling excellent adhesion
  • One step process to achieve 25–30-micron thick coating
  • No toxic or heavy metal ingredients and formulation has near neutral pH
  • All processing under ambient air conditions


Thermal Shock Resistance

  • Microstructure designed with controlled and thermally stable micro- and nano-porosity for high toughness
  • Good strain capability and excellent thermal shock resistance on coated steel, aluminum, titanium, and other commonly-used alloys
  • Low coating modulus accommodates high CTE mismatch stresses

High Emissivity

  • Hot spots in piping exteriors of industrial high temperature processes (above 1000°F) cause accelerated degradation of alloys. HTP-100's durable high emissivity spreads heat uniformly across coated surfaces.
  • Promotes high-efficiency heating at high temperatures
  • Improve radiative heat transfer in energy-intensive service environments

Vacuum Compatible

  • No outgassing under ultra-high vacuum
  • Protects sensitive substrates from outgassing up to 1800°F
  • Compatible with semiconductor manufacturing
