DIATEX primers and paints

The majority of paints crack as the covering ages, the colours expected are not always precise during repairs or on first painting, the result obtained with the paint does not satisfy your quality criteria and the weight of the finishing is often too high and affects the performance of the aircraft.

DIATEX offers you a comprehensive package by providing paints that guarantee protection against UVs and ensure a perfect finish of your aircraft, as well as the following solutions:

  • Primers which adhere perfectly to nitrocellulose substrates (dope) and laminates: DIAPLAN.
  • When painting on metal; a substrate which ensures optimal grip to the anti-corrosion primer.
  • Paints that adhere perfectly on the primers.
  • The excellent compatibility of products, which eliminates the problems of separation (orange peel).
  • The high elasticity of primers and paints to avoid cracking during deformation in flight and ageing.
  • The finesse of the paints which improves the characteristics of the aircraft by facilitating airflow.
  • The precision of the colours that are produced according to the RAL standard.
  • The versatility of the primers which can be used on textiles, laminates or dope.
  • The ease of application of our top-of-the-range finishes, accessible to non-professionals.
