Hi All,
Just tried to mix some of the boron nitride (white carbon) powder in a couple different epoxy batches from 10%-20% by weight with West Systems and could not get a good mix. Got little bumps of unmixed powder in spite of 2 min mix with a stir stick for the epoxy and another 2 min. after adding the boron nitride- at room temp. I think it was Paul that suggested the product and 15% mix ratios. Anyone got any tips on how to get the stuff to emulsify better? Have enough to do a second coat and expect I'll get the colour to be more consistant- little streaky at the moment. I will have to sand open the little powdery bumps before applying the second coat but sure don't want to have to do that after the final coat. Keep up the contributions everyone. I check this site even when I'm not building. I like reading everyone's oppinions bout stuff- and builders from other countries... Paddlers everywhere seem to have a pretty similar take on things...
