Default Sticky Tape for UHMW

I have found a way to stick slick plastics like UHMW or any other plastics to jigs and fixtures.

Check this out:
FastCap T20034 1" x 50' Speed Tape - Masking Tape - Amazon.com

This Fastcap outfit has been really busy the last few years. Some good products, competitive pricing..
this tape might well be worth a look..

Herb, Can you elaborate on the tenacity of this tape used with UHMW? Typically, I've had to use screws, bolts or rivets when building concrete forms with UHMW. We've been unable to locate an adhesive or tape that could really work.

Thanks so much,

Otis,
I haven't used it in wet conditions so not sure how it would perform. Concrete forms? boy that is a new one, How high are the walls? That is an interesting concept,tell me more about that.
I have used it to hold 1/2"-1" thick UHMW to wood templates for routing instead of foam tape. It was so sticky that I used some to keep the plastic pads from coming off my clamps.
I will have to test it underwater and see if it holds up.

Herb, Thanks for your reply. I will order some and give it a try. My patented product line is called Pocket Form Isolator. It forms concrete, but rather than for walls it holds concrete separate from the soil around it using injection-molded HDPE SF parts. The concrete forms are used for piers and column isolation pockets. Most of our sales are in the USA, but we do have a presence in other markets where English is spoken and the dollar is strong. Actually, my use of UHMW would be only for some low-volume "in-house" work that coworkers and I will be doing to create some molds for a totally new and completely different product line for which I am also the inventor.

Thanks again!

Otis, I did an immersion test for 12 hours under water smooth plastic to smooth plastic,and it was still adhering but lost a lot of its adhesion properties. It was not hard to separate and once parted immediately lost its adhesion properties. Before immersion it was almost impossible to part the two pieces. I think it might hold for awhile under damp conditions, but not long term.
I would not recommend for that use. But under interior use it has phenomenal adhesion.
Hope this helps,

Herb

Hi Otis

Another place to try is All Star Adhesives. They specialise in closed-cell gasketing for CNC routers but they also used to make a very good double-sided tape for small/awkward/plastic components called zGrabber

Regards

Herb-meister, Thanks for your test and corresponding information. I still will order some for my shop use, as we are going to be forming with silicone and UHMW for many items to develop one of my new product lines.

Phil my buddy from across the Atlantic, Thanks also for your info - I will order some of that stuff as well.

My invention projects cause me to need numerous and diverse sources of a wide variety of slightly unusual products.
