Questions about styrene vs abs

[G3750]

George, please tell us about the E-6000.

When I've worked with high-impact styrene, abs and other thermoplastics, acetone seems to evaporate too quickly. I can't recommend it. MEK works much better, but you need to provide lots of ventilation. Try not to breathe it at all, if possible.

E-6000 is a slow acting, medium viscosity, industrial adhesive (I think it's a CA). It's waterproof, non-flammable, and provides a permanent bond. You can find it at A.C. Moore, Michaels, Hobby Lobby, Home Depot.

It's not a CA. It's 10-30% Styrene Butadiene Copolymer in 60-100% Tetrachloroethylene.

I'd not be breathing any tetrachloroethylene

Does anybody know if there is a difference between RTV and E6000?


The only difference I have noticed is RTV is soft when set while E6000 is stiff.

Not even close. RTV Silicone is methyl/ethyl siloxanes with acetal acid curing agents. Smells strongly of vinegar as it cures. Very waterproof once it cures.

And E6000 is tetrachloroethylene with styrene butadiene copolymer. Very waterproof once it cures.

I may have misread your question. I was looking at the chemical and toxicity issue as opposed to whether these are decent adhesives. I tend to use silicone stuff for waterproofing/weatherproofing. The few times I've tried to use silicone adhesives for general purpose work it hasn't gone well. The things that are an advantage for weather/waterproofing tend to work against it as a general purpose glue.

Wayne, what do you use the E6000 for? What advantages does it have over consumer-grade crap? Do you need a drone to apply it a mile away, to safely use it?

Answer 1) Everything. Seems to stick equally well to aluminum, brass, steel, wood, glass, PVC, ABS and Styrene.
Answer 2) It sticks to most things and has high shear strength when compared to cyanoacrylates. It remains flexible (like RTV but stiffer.)
Answer 3) Depends. Some people complain, "It really, really stinks." I rather like the smell, but it does permeate the entire house. This material is considered hazardous by the OSHA Hazard Communication Standard (29 CFR 1910.1200). Skin corrosion/irritation--category 2. Serious eye damage/eye irritation--category 2B. Carcinogenicity--category 1B.

What do those numbers mean?
Risk level 2: Materials hazardous to health, but areas may be entered freely with full facemask self-contained breathing apparatus that also provides eye protection.
Risk level 1: Materials only slightly hazardous to health. It may be desirable to wear self-contained breathing apparatus.

I do not know what the letter "B" after the numbers means.

I read those risk levels as: Risk level 1. same as being outside at 2 PM in Lakewood, California; Risk level 2. same as being outside at 2 PM in Carson, California.

Have you ever been in Carson in the afternoon? Some of those refineries smell a lot like E6000.

First time I used E6000 was to glue some black stones back into my wife's Indian jewelry.
The jeweler had tightened the crimps but the stones still fell out.
I put them in with epoxy and told her, "Now they will not fall out!" They fell out. The epoxy did not stick to the back of the stones.
After cleaning the epoxy out of the silver setting I tried fish aquarium RTV. It sticks to glass, it should stick to stone (rocks and glass are both are silicon right?) They fell out.
The lady at Michaels Crafts said most people use E6000 for jewelry. I tried it, it worked.

I had a knob on my old washing machine split. The appliance parts store said the handle was not available.
Hobby shop plastic glue didn't even phase it. When I took the clamp off after 24 hours it just fell apart.
Tried acetone. Would not melt it. Epoxy seemed to work until I installed it back onto the washing machine. It split apart while putting it back on.
E6000 held it together for a whole year. The failure mode was it lost its grip on the plastic. I glued it back together and it held another year. At that point the machine was leaking water through the transmission so I replaced the entire washer.

Thanks for that, Wayne.

damage/eye irritation--category 2B. Carcinogenicity--category 1B.

I do not know what the letter "B" after the numbers means.

Category 1B
Substances presumed to have carcinogenic potential for humans.
The classification in this category is largely based on animal evidence,
animal experiments for which there is sufficient evidence to demonstrate
animal carcinogenicity.

The only redeeming property of tetrachloroethylene is its lack of flammability.

Hmm. I am seriously thinking about going with something like Loctite Power Grab as a general purpose adhesive. Is that safe and effective?

tetrachloroethylene. This stuff has done in a few dry cleaners. It's a real beast when heated.

What's the OSHA Hazard Communication Standard (29 CFR 1910.1200) rating of a hot dog?

Pretty sure it was trichloroethylene that used to be a standard for dry cleaning, however, you point is quite valid - pretty sure that that stuff was banned for that use; only ever had 1 bottle of it in my labs - glad when it was gone, too!
