15.6 Paint repairs
15.6.1 Safety rules
When working with paints, thinners and solvents follow the following safety rules:
•
it is necessary to follow safety rules for working with flammable and volatile substances
•
working area must be properly aerated
•
it is prohibited to smoke and anyway handle with free fire in a working area
•
use protective working means such as goggles, gloves, respirator, etc.
15.6.2 Recommendation for additional surface treatment of the airplane surface
CAUTION: BY APPLYING PERMANENT PROTECTIVE COATS WEIGHT OF
AIRPLANE IS INCREASED AND GRAVITY CENTER POSITION IS
CHANGED. INCREASE IN WEIGHT DEPENDS ON TYPE OF COAT AND
ITS THICKNESS.
15.6.2.1 Washing and degreasing
It is possible to use both organic solvents and solvents based on water.
(a) Organic solvents acetone, metyetylketone (MEK), benzine, toluene,
BASF Glasurit 360-4
•
Applied by spraying on washed surfaces (e.g. mechanical sprayer, jet ejector) or
by wiping with wet (by pouring, not by dipping because it would contaminate the
whole volume of solvent) textile wad. After applying it, the agent is wiped of by clean
absorbing material before solvent evaporation.
•
Advantages : fast and reliable evaporation even from the corners and borders
without additional warming
•
Disadvantages : it must be used without other dilution (expensive); not ecological
(danger of water contamination); detrimental to health (must be carried out in an
aerated area with personal protective means); waste (including dripping from the
area) must be eliminated in the incinerating plants.
•
Use : for Al-alloys surfaces, epoxy fiberglass
