Coatings Systems

Topcoats

  • Aeroglaze® Z306 and Z307. These moisture cured polyurethanes provide a matt black nish with extreme durability, mar resistance, cleanability and resistance to environmental degradation. Many scientific evaluations of Z306 have established its properties for the high absorption of wavelengths in the visible spectrum (low reflectance), combined with low emissivity in the infra-red spectrum. These properties ensure maximum absorption of stray light & minimum scatter combined with minimum emission of heat which can disturb the light path. Z307 provides essentially the same properties with additional conductivity for the discharge of static electricity.
  • Aeroglaze® A276. Gloss white finish provides extreme durability in harsh environments typical of aerospace and space applications. A276 provides high re ectivity in accordance with space industry requirements
All Aeroglaze® topcoats perform their functions in vacuums and with low outgassing.

Primers

Lord Aeroglaze® primers provide enhanced adhesion and corrosion resistance for a wide variety of substrates used in the space and optical markets including; gold, aluminium, stainless steel, copper, silver, beryllium, magnesium, glass, nickel and FRP. Pexa also supplies the Lord Chemlok® range of adhesion promoters for a wide variety of challenging substrates. The primers have been tested in combination with the topcoats to ensure that systems meet the technical requirements of the space and optical industries.
  • Aeroglaze® 9924.-Wash (etch) primer containing chromates suitable for a wide range of substrates including untreated aluminium, copper, silver, gold, galvanised steel and many other alloys.
  • Aeroglaze® 9947. Wash (etch) primer chromate free suitable for a wide range of substrates including FRP, untreated aluminium, copper, silver, gold, galvanised steel and many other alloys. Allows compliance with regulations such as REACh if chromate pigments are not permitted.
  • Aeroglaze® 9929. Epoxy primer containing chromates is suitable for a wide range of treated metal substrates. This primer additionally conforms to the requirements of Mil-P-23377.
  • Aeroglaze® 9741. Epoxy primer chromate free suitable for a wide range of treated metal substrates. Allows compliance with regulations such as REACh if chromate pigments are not permitted.
