CHAPTER VII
F.R.P. LAMINATION TECHNIQUE
The following procedure should be used to!
laminate the keel, the bulkheads and all other!
laminations required.!
MATERIAL!
To laminate the keel and bulkheads, you!
require a 45 gal. drum of resin which has a wax!
content, 1 gallon of catalyst n 50 M , 2 X 5 gal.!
of acetone, one roll of 24 oz. roving, and one!
roll of 1 oz. or 1-J- oz. mat. Do not leave the!
resin drum in the sun. Do not allow your roving!
or mat to become wet or even damp, since the!
resin will not catalyze.!
CATALYZATION!
To catalyze, you will need one gallon of!
methyl-ethyl-ketone-peroxide or MEKP at 50$ proof.!
Depending on the temperature, the percentage of!
catalyst is from 1 to 2 %. The warmer the!
temperature, or the thicker the lamination (l/4 n!
or more), the less catalyst will be required. Do!
not catalyze less than 1$ but do not over catalyze,!
since this could cause the resin to self-ignite.!
After doing laminations, be very cautious.!
Do not leave the boat until you are sure!
that the catalyzation reaction is over or at least!
past its peak; this is indicated by a cooling of!
the laminations.!
