15.6.2.2 Bonding rivet heads, big irregularities and material transitions
CAUTION
In case that airplane surface remains without top coat, carry out just rivet head bonding.
After perfect degreasing carry out bonding of rivet heads, big irregularities and transitions of
fiberglass parts with Al-sheet.
Epoxy and polyester bonding agents for car bodies are suitable; moreover for transitions
between two types of material with increased elasticity. Recommended bonding agents are
shown in Tab. 15-4.
Polyester bonding agents are applied with plastic spatula after being mixed with initiator.
Sanding with sanding paper with grain size of 240 is made to smooth surface after drying.
Remove dust after sanding and clean with degreasing agent.
Epoxy bonding agent is applied from the special jet with static mixer by means of extruding
pistol. Excessive material is wiped off with spatula to final appearance before setting (slight
recess is not a defect) -
do not sand !
