Low outgassing, white, silicone, thermally radiative, paint


APTEK 2719-A/B is a white, flexible, mineral oxide filled, two component, room temperature curing, silicone coating/paint designed for the wide operating temperature ranges of space applications.

APTEK 2719-A/B was developed for use as thermally conductive coating where excellent resistance to intense UV light exposure is required.


  • Field-approved formulation; already on hardware in space
  • Low outgassing silicone binder provide coating with a very wide service temperature range of -320°F to +400°F (-195°C to + 205°C)
  • Passes NASA outgassing per ASTM-E 595
  • Inherently has sufficient surface conductivity for ESD applications on conductive surfaces
  • Formulated to sprayable viscosity for convenience
  • This coating is tough and flexible and can be used on almost any substrate without fear of cracking or stress buildup during temperature cycling.
