HTP-100 Overview

HTP-100 is compatible with a wide variety of substrate materials due to micro- and nano-porosity along with a low coating modulus.

Some examples of materials which have been tested extensively for compatibility:

• Aluminum (>23 ppm/°C)
• Stainless Steels (10-20 ppm/°C)
• Titanium (8-10 ppm/°C)

The GIF to the right shows the coating remaining intact during a hot bend test, demonstrating its strain tolerance.

Many high-emissivity EBCs are susceptible to degradation in highly reactive environments like molten salt, while HTP-100 is chemically stable against molten salt degradation.

The images shown right are from an experiment to demonstrate how Cerablak® HTP-100 protects refractory bricks from molten salt exposure (sodium and potassium).

The SEM and EDS images show that the salts were confined to the surface. The coating also demonstrated excellent mass stability, with coated samples gaining only 33% of their mass during immersion, compared to uncoated samples that disintegrated.

• 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

HTP-100's durable high emissivity spreads heat uniformly across coated surfaces at temperatures up to 1800 °F

• Promotes high-efficiency heating at high temperatures
• Improve radiative heat transfer in energy-intensive service environments
• Minimizes Hot spots in piping exteriors and associated degradation of alloys
