Resin Question

This stuff looks pretty cool....

Thanks Solar Eagle, looks amazing only perceived issue would be cost for consumer applications but specs. are good.

It sounds like a prepreg tape. Search for Prepreg Uni-Directional Tape - TCR Composites or similar.

Thanks Lyn, It was not a tape and to add info I am positive it was 2 part, also they claimed all you needed to spray it was a dust mask and there were no fumes to evacuate. On thing for sure was it could not tolerate any silicone in the area. This is very similar to some paints ( coatings) we used at the time. The sample I had but lost was produced by spraying it on a pane of glass then cut into strips for samples.

Would you tell us your intended end use of this mystery material?

At the time I had intended, funds permitting to construct vehicle accessories, the advantage due to the speed of setting and lack of heat would mean only one mold to achieve production where as using polystyrene would require multiple molds and several hours of cure time. If I had it now who knows what items may be conjured up.

Two things:

1. polystyrene is hardly ever used for automotive applications, due to its poor physical properties.

2. Polystyrene is a thermoplastic and requires virtually no cure time. Typical cycle times are in the range of 30 seconds.

Polystyrene - Wikipedia

My error I meant A polyester resin resin with an unsaturated polyester backbone which is catalyzed with a peroxide. Weekend fatigue.

Not to be critical.

Can you give us some examples of your conjured ideas ?

Nothing in particular but back in the day truck steps and truck camper tops were considered. A depression caused by corrupt government in Canada put an end to any plans at that time, now time in general has taken its toll but I am still thinking.

Could be a polyurethane resin.

I used it in Europe years ago and got it from

VOSSCHEMIE - they must have a representation in the USA too I guess.

Worth seeing

Great I will look it up , thanks.

This sounds like a Glycol-urea-formaldehyde resin. They are highly flexible.

Thanks Ed I will research this.

Most bedliner materials (think LineX or RhinoLiner - no endorsement) are made from polyurea resin. If used with a chopper gun, I can imagine the results you describe.

Thanks Troy I forgot about the spray in liners. When I was associated with BodyGard they gave the formed bed liners a quick spray ( splatter ) of similar product to eliminate most of the slippery factor of HDPE box liners.

There are many flexible thermosets ... many rubbers, some polyurethanes, some silicones. If thickness is constant you can get density by weighing a known area. Behavior in a flame and chemical resistance (what dissolves it) may tell more.

Very true and I think we have it narrowed down enough that I can target my research. Thanks for the comment.

head to home depot and find yourself a fiberglass repair kit. it will have the fiber mat that you can cut to what ever size you would need and also a can of two part resin. you mix the resin with a catalyst and apply it to your fiber mat. depending on the amount of catalyst, work time can be 10 mins to 1 hr. an item that is opaque and is more like a paste is called bondo which is polyester resin. i might add that there is also an epoxy system that can be used. the website below has a couple of interesting coatings that may have what you are looking for. urathane for the most part foams when in contact with water or CO2 (gorilla products, great stuff, ect).

Thanks everyone I think I have enough to go on for now just need to find the time to complete my examination of the options.
