A two-component viscous epoxy was used for bonding the lami-
nate to the steel flange surface. The mixing ratio of the epoxy was
one part resin ~bisphenal A based! to one part hardener ~polyeth-
ylenepolyamin ! by volume. The epoxy had a pot life of 30 min at
room temperature and was fully cured after 2 days at 25°C. This
epoxy immediately reached high tack consistency and was ideal
for over-head applications.
