Re: Bayliner 2252 exposed to fire and intense heat. Is it worth restoring?
Like oops said, the glass does not burn at these temperatures, we do testing to evaluate the glass to resin ratio by burning the laminate, it leaves only the glass, so the before and after weights are what is used.
The resin will start to be affected at about 170F, at this point it will soften slightly, but will become solid again and be fine, the shape may (can) change slightly though. The exact temperature will be different for each resin, some a good bit higher, some just a little lower.
As it becomes hotter (200+) the resin will start to break down, at this point it will be much weaker when it cools. Again, this depends on the resin, VE can tolerate much higher temps than a standard resin, but it will vary even within types of resin.
Without looking at the laminate first hand it will be difficult to tell how bad it is. A long semi hot fire will do much more damage than a short very hot fire, in a short fire there just isn?t enough time for the heat to migrate through the laminate.
