Re: If we want retroreflectivity as well??

Re: If we want retroreflectivity as well??

I just had a wild idea..

The industry uses glass beeds for...eehhrrr..whats the word in english...removing paint and rust with a mix of high pressure air and glass beeds.

These guys:
Potters-Ballotini Ltd
Pontefract Road
Barnsley
South Yorkshire S71 1HJ
Tel: +44 1226 770381
Fax: +44 1226 207615

They manufacture it. Perhaps you can talk them into sending you a sample? Mind you, this is PURE GLASS BEEDS, so you have to mix it with with some clear "carrier".

//EDIT//
Found another one. This time you can select beed size
0- 50 m,
065 - 105 m
075 - 125 m
090 - 150 m
100 - 200 m
200 - 300 m
300 - 400 m
400 - 600 m
400 - 600 m

The price is about $60 for 25kg. Yes, minimum pakage is 25kg.

Re: If we want retroreflectivity as well??

Thanks for the additional bead sources Robert!

You failed to give a name and contact info on the last source.

BTW, the term in English you were looking for is "sandblasting" or "beadblasting".

I have pleeded for a 500gr free sample of their finest beeds fram a manufacturer in Sweden. If I get it, I will mix it whit matt clear top coating and paint it on top of the potential N9.

Re: If we want retroreflectivity as well??

the smallest bead size i can see on the site is 65 microns which is probably larger than what we need.

Yep; nice try, but no cigar.
Does that phrase have any meaning outside of the U.S.? If not, I'll explain later.

Those beads would be too large (we are looking for beads smaller than 50 micron). I'm not sure, but I think those beads were also white in color and not clear.

3M makes a lot of stuff we would love to try, the problem is finding a source for it and the cost. Unless you buy stuff by the train-car load 3M isn't interested in selling to you directly.
