suncure

I think I’m going to go with suncure resin on my new board, are there any drawbacks to using it? How does it stand the test of time? works good with Volan? thanks JR

JR- I’ve only been using it just short of a year now. Clear lams seem to stay whiter longer, no structural tradeoffs that I can see. For the homebuilt board I can’t find any fault with it. Fewer fumes, much less concern over temperature ranges and less waste. You can do tints but not opaques, use it for lams, hotcoat and even gloss. I don’t know why you couldn’t use it on Volan cloth just as easily, maybe better given all the time you need to work with the lamination. I’ve only mixed my own from SunCure powder mixed with Silmar resin, so no comment on premixed or other systems.

I’ve also used sun cure resin for about a year and I love it. Make sure there is no sun light getting into the shop area because it doesn’t need direct sun to kick off. We get quite a bit of rain here on Kauai and there are times I’ve put a fresh lammed board under a canopy to kick, it takes a while longer to kick but it works, UV rays are bouncing all over the atmosphere . I use the premix from Fiberglass Hawaii, Costs about $15.00 more for 5 gals but you’re not buying catalyst and what you don’t use can be put back in the container to be used later. You can even use it with catalyst like conventional resin if you like.If you use it for hot coats you have to double the amount of surfacing agent and let the board sit( so the wax can come to the surface)for about 10 minutes before putting it in the sun. I personally use it with catalyst for hot coats, after it goes off I then put it in the sun to get a quick cure.

Don’t know if you are into laying up your own fins or not but suncure sure makes nice fin panels, even tinted. Layup to cutout in just hours not days. What a treat that is, takes half the work out of fins. TS>>> I’ve also used sun cure resin for about a year and I love it.

How little or how much light can be used in this room when glassing? I think I would like to try it on my next board thanks Mark http://www.scottsurfdesigns.com

Tom, Could you please give a quick rundown on how you make your fin panels with suncure. I’ve never made a fin before but I’d like to try making a single fin. Thanks!>>> Don’t know if you are into laying up your own fins or not but suncure sure > makes nice fin panels, even tinted. Layup to cutout in just hours not > days.

What’s really fun is putting on glass on fins with suncure. Kokua

I use a 3/4" piece of plywood as a work surface, cover it with wax paper, pieced together with masking tape works fine. Decide on your dimensions, I use 15" x 24" , it works with 30" cloth well. Cut your cloth up and stack it in sheets of 5 layers. I made my last ones for FCS boxes so your layer count will vary with the boxes you are using. I believe 30 layers of 6 oz. cloth works out to proper fit for Fins Unlimited type long box. FCS- 25 layers, and I used every bit of 56 oz. of suncure UV catalyzed resin which I tinted blue. Layup 5 layers at a time, working ALL the air out and really concentrate on wetting all the cloth out. Five more and so on until you finisht. No reason to hurry if you have your lighting setup right. I walked it out into the sun (last one was a 40 degree day, try that with catalyst!) Within minutes it was curing to the point I could lift the panel up to cool it some. I was cutting fins within a couple of hours. I use straight lam resin, no wax solution and do the cutout and foiling like this. You can finish them with a brush job using a hoatcoat mix also with UV if you want. Really check on the actual thickness you need for the box you are working with, regarding cloth layers. Oversize is better than undersize, it’s easy to thin them down for a close fit in whatever box you are using them in. I believe Jim Phillips posted some good numbers in the archives now about Bahne’s specs for layup of box fins. Hope that helps.
