Hi all...
I'm new here on RCUniverse, but not new to the hobby...
I have a question regarding vinylester resins... I know that they fall between polyester and epoxy resins...
For now I have used only epoxy resin and never had trouble with it... Good thing was that my father always kept 50+ kg of epoxy for his sailplane... As his sailplane project goes to an end, so our epoxy stock goes out... We used Sika Biresin SR120 resin and Sika Biresin SH120-3 hardener...
Now Igot access to cheap (read free) vinylester resins mixed per my needs by my friend who works at the resin factory...
I would use vinylester resin only for covering my models with lightweight glass cloth and Iwould still use fast setting epoxys for construction...
Is vinylester suitable for such application?
Cheers,
Robert
