5.6 Paint repairs
5.6.1 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.
5.6.2 Recommendation for paint repairs
With considering the large proportion of laminates in the construction of the airplane is
recommended:
follow the paint scheme catalog issued by the airplane manufacturer - available by dealers and on
www.evektor.com
web address (the dealer section)
do not park the airplane longer time on bright sun or rain
–
use covers offered by the manufacturer
or park in hangar
do not paint with dark shades of colors - especially the laminate cabin and legs
application of painting to be performed by or car paint shop
In the case of paint repairing use the same or equivalent painting system as airplane manufacturer
uses
By applying paints weight of airplane is increased and centre of gravity position is changed.
Increase in weight depends on type of coat and its thickness.
CAUTION
Failure to meet these recommendations reduces airplane lifetime
5.6.2.1 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 off 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, epoxide fibreglass
CAUTION
These agents must not be used for degreasing parts from plastics (PC - Lexan, PMMA - Plexiglas
)
(b)
Water-based
agents
- emulgation substances, wetting agents
