Question For Greg L.

Hey Greg…We just got a chance to try out your resin and i am very pleased so far with the results. We have used it on our KiteBoards and are just pleased. It took a little longer to kick then expected, we where vacuum bagging, do you think that has an affect on its curing time? I also just hand layed a surfboard with it and it works good. I thought i would have a problem with my laps but it folded and held perfect. My main question is what pigments can I use in it? Can I use the same stuff i use for my polyesters? Also is there any special paints I need to use on the foam or can I use standard water based acrylics? Thanks for your help and great product. Klein http://www.kleinboarddesigns.com

On the speed, were you using the fast hardener? If your vaccuuming with fast you can usually pull it out of the bag in about an hour and a half. That depends on the project though, some need more time. If you want it to be faster, put some heat on it. Doesn’t take much, just a few degrees makes a big difference. If you got it to just 100º you can probably pull it out in less than an hour. If your using heat be sure to support the project so it doesn’t warp. Most standard pigments work fine. If you have quesions the best thing to do is a small test batch. Then you KNOW. And water based acrylics are fine for airbrush.

Thanks Greg…we’ll keep that in mind. We are using the slow hardener. What are the time differences in the slow and fast as far as bagging and hand laying. Thanks for your help. Klein http://www.kleinboarddesigns.com

Bagging doesn’t usually change cure times that much. The fast hardener cuts your time in half. Many times using slow is about getting the stuff ready to put in the bag. Getting all your “ducks in a row” before you start will shorten that time and experience will give you better methods which will eventually let you use the faster hardener which will, of course, lead to shorter bag time. Bag time on the fast should be under two hours. Slow will leave you in the bag for 4-5 hours. Then there’s the extra slow which gives you 4-6 hours work time but will be in the bag 12-18 hours. This is used for very large projects like boat hulls. To estimate when the part can be pulled from the bag, put a bit of wet resin on the outside of the bag and when that is sufficiently kicked you’ll know. The hardeners can also be mixed. Mix fast and slow together and get a medium. One of my next projects is to test different mixtures of hardeners and publish the results.
