Ebalta OH 33...


I`ve been using formenharz F200 in combination with F260 for edges. I`ve been having some trouble with the quality of the F200, giving irregular surfaces with the last few batches I`ve used. -I know it is not my fault, as I`ve built over 20 moulds the last few years... Now I want to exchange the F200 with the Ebalta OH 33, as I have heard nice things about it...

My question is: Can I use the F260 for edges, with the Ebalta OH 33 for surface?

Also, where to buy the OH 33?

Hi Kjell!

You should get in touch with Burkhard Dotzauer. He is a scale-modeller with a lot of experience, working for Ebalta and his wife is selling resin and stuff from Ebalta to modellers. He will for sure be able to help you with your questions:

Dear Kjell,

as David mentioned before, you could call a regional sales agent or Ebalta directly at: http://www.ebalta.de/ISY/index.php?call=en-vertrieb

Since OH 33 + hardener CH1 is a cold curing epoxy gelcoat which cold be postcured at elevated temperatures to reach a higher Tg, i don´t see any problems arise in combination with the F 260, as it´s virtually the same like F 200. But to say it clear: i would recommend to use a gelcoat systems with hardeners that are within the same temperature range or even the same product, to avoid any incompatibilities

Thanks guys! Here is a picture of the fault I get in the F200 gelcoat. Any advise how to avoid this? I know others have the same problems with it..
