Place of use:

The strength of hull plate in yacht factory by vacuum molding is 20% more than that of hand-made layer, at least 30% of labor is saved, and about 30% of resin is saved.

Resin used:

SWANCOR CHEMPULSE 901-V resin for vacuum infusion

The low viscosity is about 250 ± 50cps, and the resin with low viscosity is better than that with impregnation.

Method:

After the preformed mold shape is poured and vacuumized, the mold is filled until the resin impregnation is completed.

Key points:

The gelling time is about 90 minutes, and the longer the hardening time, the better. The thread printing after molding is less than that of up resin, and the strength is also significantly increased; HTD is higher than up resin, and the reaction heat is below 70 ℃ (avoid damaging the PVC foam material).
