General Sanding Principles and Heat Management

finish I mean it starts with an abrasive I guess is what it is and all the braces are everybody just needs to keep in mind it's not complicated it's just a cutting tool it's no different than a bandsaw blade it's no different than a router or shaper You're simply taking tons and tons of little knives and you're adhering it to a substrate so when you're cutting things what do you want to do you want to run cool because heat is the biggest detriment heat is the Kryptonite like this to Superman that's what heat is to sandpaper once you heat it up you start loosening the grains and that's when you start getting shedding and that's when you start loading and a lot of things go wrong so in that point if I had to give anybody any tips about sanding especially on what you're customer base is doing my first advice is don't use too much pressure if you're using a three inch by four sander or if you're using a five inch sander just let the weight of that machine do the work and look I get it if I go home and do drywall or something I'm sitting there and I'm I'm going to town at it but I'm creating a lot of friction so just letting away that sander do the work is is going to do the job these tools are designed to crack and resharpen that's the term in the industry is called friability and that is a major term in our industry so what that means is you're all abrasive grains start out sharp because they're electrostatic coated so when they're coated that that electrostatic actually the grains come in on the bottom and they flip up and stick to the resin on the top but because electrostatic coating you're getting the heavy side of that flipping up so you always have a sharp tip but where we really I think Excel is we focus on wood 75 of our businesses would so we have some very special grains so a lot of companies
