Saw Blade Anti-Friction coatings

[axa]

I was cutting some 1/2" thick acrylic plastic with my stock blade on the BT3.
As the blade speed was too fast for this application a bit of acrylic plastic melted to the blade.

I thought to clean it off with acetone which melts right through plastics.
Problem is it seemed to just as easily wash away the clear BT3 blade coating.

My question is, what was that stuff... as Id like to reapply it. I know how important blade lubrication is, as well as protection from rust and the like.

As I look at other blades they may have a baked on teflon or such coatings, but this was certainly a sprayed or brushed coating.

What would be a suitable substitute?

you don't really need to blade to be coated with anything. the more expensive blades get the less coating they have. industrial blades have no coating.

So you reckon this is for the most part just a gimmick?

yep. I'm sure it helps something but if you look at blades that are over $100, and are larger then 10-12" you won't find any coating. forrest doesn't have a single coated blade in their lineup and I don't think tenyru does either.

They do help prevent rust and make cleanup easier, and they're supposed to help reduce friction for those occasions when the work piece contacts the body.

The red, yellow, black, and orange coatings make it alot easier to pick out of the blade rack too!

I like to put a touch of beeswax on mine. Bandsaw blades too. Guy up the street has bees so I get it locally for a little bit of nothing.
