For Sale Light trap flocking sheet material

[Dan Daniel]

SOLD- see last post

OK, a strange item but might be of use to some of you. This is a thin flat black light trap material sold for use in telescopes. Sort of a velvet surface. Adhesive backing. In use when applied, it is less than 0.4mm or 1/64" thick. It makes a nice light seal to replace foam or felt or velvet. For example, many folders have a thin material next to the back door hinge.

I started using it to line the interior of the film chamber on YashicaMat TLRs. They used a semi-reflective paint and the light trap killed the internal reflections and made a visible improvement in image contrast.

It is sold by the inch- $0.25 per inch for 11 inch wide material. I was running out and needed to get a bit more. Maybe 20 inches will see me through the next fifteen years. So, pay $10 shipping to get $5 of material? I ordered some more thinking it might be of use to others.

So, I will send 3 pieces about 4" by 9"- business envelope size. $2 of material, $1 'shipping.' $3.

If you have an interest in more, larger pieces not cut, whatever, let me know. I'm not going to make money on this, more of a public service to get smaller pieces out there to people who can use it.

Nice, I'll be looking for stuff like that when/if I manage to 3D print a 400 foot bulk loader. Look for PM.

Looks as if a 2 ounce letter envelope to Italy will be $2.43. So call it $2.50, $4.50 US total. Please DM me through here for my paypal address, or we can discuss other ways.

I used this exact stuff to flock the inside of a Sputnik. Worked great, and the adhesive is better than you'd think. GLWS.

Sent you a PM, Dan.

SOLD OUT. Thanks for everyone's help in getting rid of my excess purchase.

I do recommend this material if you work on old cameras, are building your own, etc. It is thin- ~1/64", 0.015", .040mm. Quality- does not shed or flake, etc. Sticks well. Works as both a cover for surfaces and as a very thin light seal for doors and such.

Supplier info in first post. Sold by the inch. Not sure what the minimum is, but shipping remains around $10 for up to 100 inches or so. It took about 4 weeks to get to me, so I imagine that the outfit puts such orders low on their list and does runs of small orders every few weeks.

Maybe someone else will be buying some and can do this same thing down the road. I had about 12 inquiries in less than 12 hours. Partly the price, of course, but does show that people are curious and have uses. Three sheets at 4" x 9" will last a long time in most cases. I am on the last I bought about 6 years ago and the adhesive is still strong, shows no signs of drying out.

Once again, thanks for offering this. I've wished for pretty much exactly this (replacement film cassette velvet, anti-reflection flocking, etc.) and had no idea where to find it. I'll bookmark this thread so I can find it again in the future, if/when I need more or a larger quantity (say, if I rebuild my telescope).
