Secondary bond?
Have a glass fibre moulding, which needs to have another glass part bonded
to it, after the first part has fully cured. Would I be right in thinking that an epoxy resin system, with proper filler added so it aheres to vertical surfaces, would be the best way of going about this? TIA Rob |

Yes, but for best strength you need to rough up the cured part with 80 grit sandpaper to also provide a mechanical bond. -- Evan Gatehouse you'll have to rewrite my email address to get to me ceilydh AT 3web dot net (fools the spammers) |

I like to grind down until I see the threads of the cloth almost showing or
just starting to break through. Less resin better bond is a primary rule of glasswork. It also fairs better. I also like to thicken with milled glass fiber rather than the usual bulkers and cabo. It's the best way to strengthen the weakest part, "the resin". ----- Original Message ----- From: "Evan Gatehouse" Newsgroups: rec.boats.building Sent: Friday, December 31, 2004 5:54 PM Subject: Secondary bond?
