Gel Coat Question
Does anyone have any info about the gel coat used by Schempp-Hirth over
the years. In particular, I'm curious if SH has changed their gel coat over the years and if so, when did they change? I'm hoping that more recent built gliders (late '90s) were made with a newer type of gel coat than gliders made say in the late '70s or early '80s. Many thanks in advance, Gary |

Gel Coat Question
To my knowledge SH is still using T35 already used in the early years.
Of course one can order a PU finish for new sailplanes. Gary Emerson schrieb: Does anyone have any info about the gel coat used by Schempp-Hirth over the years.

Of course one can order a PU finish for new sailplanes. True. They still use the T35, although the composition of the gelcoat has changed over the years. I am unsure of the details of what changed. Trying to discuss this with the factory over the years has always been a sore point, as the gelcoat seems to last about 2 years in the southern hemisphere before one needs to consider sanding it back and painting it in Urethane (damn that missing ozone which has nothing to do with greenhouse gases apparantly!). Unfortunately this is an expensive exercise for a new aircraft, which is why the offer of a PU finish is a welcome one from the factory. Chris |
