Jaynew 0 Report post Posted February 15, 2019 I'm having trouble getting the right % of microballons. Was wondering if anyone could help me with a rule of thumb on the % to use. Making a 5 inch swimbait. Quote Share this post Link to post Share on other sites
DaBehr 122 Report post Posted March 20, 2019 Do you mean micro-balloons as in the white "powder" that can be used to make plastic float??? If so, be advised that micro-balloon are a significant lung irritant (hazard) and should be used with extreme caution. Personally, I would never use them. Some info: http://www.tackleunderground.com/community/topic/26222-safety-with-resins-and-micro-balloons/ ...microballoons are borosilicate glass and when inhaled chronically can cause silicosis (permanent scarring of the lungs). I work in the abrasives/grinding industry and have personally viewed ceramic dust under a SEM, and have seen many particles often as small as 1 micron by 4 microns. Hence, your dust mask and/or filter is not removing them. When you sand microballoon filled resin your dust mask is not enough. Quote Share this post Link to post Share on other sites
