FIELD: process engineering.
SUBSTANCE: invention relates to composition of priming composition to be applied to aluminium substrates. Proposed composition comprises polyene, thiol, and substrate corrosion inhibitor selected from chromium-bearing compounds. Said chromium-bearing compounds exist in amount of, at least, 5 wt % of chromium per weight of solid substance of said priming composition.
EFFECT: curing at ambient temperature, non-polluting composition.
