The subject of this invention is a sol-gel procedure for the preparation of anticorrosion coatings for solar collectors. Core of this invention are processes for the preparation of ultra thin coatings (0.5-500 nm), which do not deteriorate optical properties of surfaces. So protected absobers can be more than 20 days in slat spray chamber. The innovation was awarded by golden prize at Regional competition and golden prize of Chamber of Commerce and Industry of Slovenia for innovation in 2009. There was already submitted the world patent claim. Patent was sold abroad (Alanod, Germany).

COBISS.SI-ID: 4235290Black and coloured (red, green, blue) thickness insensitive spectrally selective (TISS) coatings were prepared for use as solar facade absorbers from polyurethanes. Their low emittance was achieved by aluminium flakes, while black pigment was added to adjust solar absorptance. TISS coatings combine advantages of paints (longevity, chemical resistance, variety of colours, simple application) with their spectral selectivity. The innovation was awarded by silver prize at Regional competition of Chamber of Commerce and Industry for innovation in 2009. Patent was sold abroad (Alanod, Germany).
