biggamefish Posted June 29, 2013 Report Share Posted June 29, 2013 Shore hardness is to identify the hardness/indentation of the resin material, So say a resin material have a shore hardness of 80, will the shore hardness decrease after adding micro-balloons ? if it does, how much can it decrease from 80 by adding say 30% balloons? Is there a math equation to this? I apologies if this ain't making any sense,I just wanted to get this figure out, thanks. Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted June 29, 2013 Report Share Posted June 29, 2013 I don't know of any equation, but from my time using resin and MB's, the result was just as hard and brittle. Dave Quote Link to comment Share on other sites More sharing options...
biggamefish Posted June 29, 2013 Author Report Share Posted June 29, 2013 (edited) Dave thanks for your response, did you do a cast without balloons and then one with balloons and they both felt the same? and how much balloons did you add? Im also wondering because for example the smooth on resins featherlite has a shore hardness of 58D, that's resin with 50% balloons added, I was told the featherlite uses the same resin as their Smooth cast 300 series which has a shore hardness of 70 and no balloons added, now if featherlite is the same as Smooth cast with just 50% balloons added, then im thinking the balloons does decrease the hardness of the resins. Someone correct me if im way off, again i do apologies if this is not making any sense. Edited June 29, 2013 by biggamefish Quote Link to comment Share on other sites More sharing options...
Vodkaman Posted June 30, 2013 Report Share Posted June 30, 2013 It could well be - think of reinforced concrete. All I know is that they were both hard and both snapped if I dropped them on a tiled floor Dave Quote Link to comment Share on other sites More sharing options...
