Mike- WHY IS FLEX 70 SO TEMPERAMENTAL? I have gone through every possible scenario to figure this out. I have warmed the casting resin, the mold, the insert that I'm encapsulating- and I STILL have problems with it occasionally. I opened a BRAND NEW container of it yesterday and poured up a lure. I warmed the mold, I warmed the insert, and I put a heat lamp on the mold to ensure it stayed warm so it would expedite/help the cure process. The texture of the cured product (18 hours later) wasn't "crumbly" like I had experienced before. I have learned not to "whip" it when mixing. I mix very slowly and thoroughly for about 60-90 seconds. I even fold it (cooking term used to describe a method of mixing were you gently incorporate two or three ingredients by pulling from the bottom of the container to the top, and repeating) with a stir stick from top to bottom. It was just soft- like it didn't fully cure. I know my mix ratio's of part's A and B are precise. I use a digital scale to measure out equal parts by WEIGHT. Maybe therein lies my problem. Are the A side and the B side different weights? Do I need to measure by volume and not by weight? I'm only using 27 grams of each part, so at that small of a volume if measuring by weight when I should be measuring by volume, it will definitely impact the end product. I think I may have just answered my own question, but perhaps you could chime in to solidify by suspicions. If this is the case, and the two products are different weights, but need to be measured by volume, there will always be extra resin left over in one bottle (A or B component) when you empty them by using all the product. Anyways, if you could let me know your opinion/suspicions, that would be GREAT!
Thanks,
