Thermo-optical Control

STABLE THERMO-OPTICAL PROPERTIES UNDER EXTREME CONDITIONS

ENBIO’s thermo-optical coatings are designed to survive the harsh conditions of space, and are tested to the highest standards of the European Space Agency. Thermo-optical properties remain extremely stable even after thousands of equivalent-sun-hours. The coatings are free from volatile organic compounds, essentially eliminating out-gassing and making them environmentally safe.

 

SolarBlack

TRL 6 – INORGANIC HIGH TEMPERATURE BLACK COATING

spec sheet

Solar absorption BOL 0.96 – EOL 0.96

Emissivity BOL 0.8 – EOL 0.8

Stable <-150 to >550ºC

SolarBlack has been extensively tested by ESA and Astrium and is the baseline heatshield coating for ESA’s Solar Orbiter. It will be the first line of defense for the closest man-made object to the Sun. Due to its high emissivity and extremely high solar absorbance, the coating can efficiently absorb incoming solar radiation and re-emit it to the surrounding cold medium of space. It has a unique combination of durability, thermal stability, and electrical conductivity, and contains no volatile organic compounds.

 

SuperBlack

TRL 3 – INORGANIC HIGH TEMPERATURE CERAMIC BLACK COATING

Solar absorption BOL 0.97

Emissivity BOL 0.90

Stable <-150 to >550ºC

SuperBlack is a complementary coating to SolarWhite, designed to improve on SolarBlack’s capabilities. The ceramic layer improves the emissivity, while the addition of extra pigment makes the coating even blacker. The coating is applied at room temperature in a similar fashion to SolarWhite, and retains the same inorganic and contamination-resistant properties. SuperBlack is currently being developed towards specific customer requirements; please contact us to discuss your needs.

 

SolarWhite

TRL 4 – INORGANIC HIGH TEMPERATURE WHITE COATING

spec sheet

Solar absorption BOL 0.17 – EOL 0.20

Emissivity BOL 0.8 – EOL 0.85

Stable <-150 to >550ºC

SolarWhite is ENBIO’s white thermal control coating with minimal absorption. It is currently undergoing qualification for the Solar Orbiter mission. Like SolarBlack, it is inorganic and has the durability and thermal stability that this entails. The coating is applied at room temperature and is suitable for titanium, aluminium, and CFRP substrates. SolarWhite’s absorption and emission values are highly stable, the coating is resistant to contamination, and no out-gassing occurs at high temperature.

 

Biocompatibility

TRL 4 – FLEXIBLE CALCIUM PHOSPHATES ON NITINOL, TITANIUM, STAINLESS STEEL, CoCr

spec sheet

ENBIO began life in the medical device industry and continues to offer biocompatible Skins with many significant advantages over competing coating technologies.

Corrosion Resistance

ONE-STEP APPLICATION OF CORROSION RESISTANT COATINGS AND PRIMERS

spec sheet

CoBlast effectiveness has been demonstrated with corrosion resistant materials such as zinc phosphate, magnesium phosphate, and cerium oxide. These coatings alone offer corrosion resistance and also make excellent primer layers for complete corrosion protection systems. Surface roughening and corrosion resistant primer application are achieved in one VOC-free step, with minimal waiting time before the application of a top-coat.

These coatings are currently being developed towards specific customer requirements; please contact us to discuss your needs.

 

Lubrication / Wear resistance

ONE-STEP DEPOSITION OF FLUOROPOLYMER

spec sheet

CoBlast Skins have achieved a coefficient of friction below 0.15, as measured by the pin-on-disk method. These coatings exhibit significantly reduced wear compared to the untreated substrate.

 

Hydrophobicity

ONE-STEP DEPOSITION OF FLUOROPOLYMER

spec sheet

ENBIO offers robust hydrophobic coatings with water contact angles between 130 and 140º. Superhydrophobic CoBlast Skins in development have reached water contact angles of 150° and hysteresis <10° and are relatively robust compared to many available superhydrophobic coatings.
