Adhesive Experts!

[Car54]

I am looking to bond two pieces of plastic together. More specifically this is a gauge pod for my car that is to sit on the dash. It's made of plastic and the dash is a plastic type material. I'm hoping to run a bead around the flange of the pod and set it on the dash. The bond needs to be strong and heat resistant, but but should release similar to the way dual-lock or velcro backed adhesives release when using pressure over their load rating.

Anyone have anything in mind for this?

Thank you,
Craig

Good call on not wanting to use the double sided tape. I'm far from an adhesive expert but have used Duramix products more than a few times w excellent results.

Did you ever find an answer to your adhesive question? If not, let me know. I am an adhesive expert and it's not self proclaimed either.

 

[Car54]

Nope. I used the **** it came with and it's already lifting up. I really need a semi-permanent, gel like, and non-staining adhesive. I appreciate your response.

try silicone or epoxy

Put a solid base on it, and mount with velcro. Will not move, vibration resistant. Easy to remove when you want.

I helped my brother mount a light bar on the sleeper of his truck. He didn't want to drill any holes into the sleeper so he got some double side tape from an auto trim specialty shop. ( cant remember the name but I remember it was a 3M product) I thought he was crazy but 6 months later and the bar is still in place. Don't know how you ever get it off but it must hold like crazy because my brother drives like a bat outta hell.

One word: 3M

If you purchase the 3M tape they use in Aviation that sucker ain't moving . . .

 

[mgilde13]

You say that it lifted. What did you use to prep the dash with?

 

[mrb]

look for 3M VHB tape

I had problems with my wifes Jeep rubber moldings coming off the painted metal edges of the door. I held my breath and tried Gorilla glue, it worked amazingly well, nothing but nothing gets that stuff off (of car seats too, ask me how I know). Not sure if others have had other successes with Gorilla Glue.

Alcohol and a lint free cloth.

Guys,

This pod is flat and my dash has a slight curve so I need something thick that will allow 1/4" or so of play. The last thing I used was dual lock and bent metal angle brackets...that worked well but was only holding it in 4 places. It allowed the plastic to warp in the heat. I would like something with a uniform bond the entire perimeter of the pod.

Using a gun or a squeeze tube would be ideal.

I've used 3M strip caulk in a similar situation with satisfactory results.

bring a sample to a body shop supply store and get the right tube of duramix for the application. Usually the store will rent u a gun for the duramix. I have used duramix on many different kinds of plastics and it holds up to just about anything, your part will break before the glue dose

the most important thing is to clean and prep dashboard so that u have solid base..
if u or someone else ever used armorall or similar product for cleaning dashboard, nothing will stick to that.....so u have to clean it like you did with alchohol, some paint prep solvent based cleaner, whatever...and then you can apply some plastic adhesion promoter that is used on plastic bumpers to "neutralize" any silicon or releasing agent....this should help for adhesion of whatever material u decide to use..

u can use 3m double sided tape if it adheres strongly to the dashboard....if not , then use some type of velcro..velcro is awesome solution for things that need to be removed eventually

We use 3m DP-420 to glue stuff at the shop. but it wont ever come off if you use it.

Dig through 3m's website until you find something that fits your needs

 

[srmofo]

Why not just attach it with some nice self tapping screws or small lags? Not drywall screws or something else cheesy

IMO if you find a glue that will release it and not leave a residue then its not going to hold it on in the first place. There are glues that will keep it there, but its not going to come back off ....ever.

I would use sikaflex.

I happen to work for the biggest adhesive company in the world. And based on your application and environment I'll give you my recommendation below:

Hey, we can do alot of things, but I prefer to be realistic. In the temperature ranges as well as the possible physical stresses you may or may not apply, this is your most assured way it's gonna stay. Just throw a little super glue on the ends, so I can still collect a pension off yer purchase.

Just my 2 cents.

Nice M Coupe... Cosmos, Arctic, Titanium or Imola exterior? My advice, mount the gauges in the glovebox nicely so when you open it you can see them.

Trying to make this process reversible will be a challenge.

It depends on the type of plastic you have , so you can get the correct glue for the job. is it rigid or semi-rigid, abs, or poly etc. duramix (as others have said) is the best choice as far as glues for bonding (my pro. opinion) such as 4040, 4240, 5887 etc. but, there are also some excellent bonding tapes on the market,. remember, proper prep is the key for anything to work. your local body shop supply can help you make the choice. now, if you want to go cheap GORILLA GLUE....that **** will stick to anything..

FWIW I don't believe that Dual-Lock would be the best solution to your problem but it is strong. This type of (Velcro) is in a class by itself. It performs as 3M describes and will hold at least 4 times better than standard Velcro. Pricey but if a panel needs to be removable later this is the type (Velcro) for the application. I use it on aircraft interior panels and carpet. One point to make is to stick it to bare metal cleaned with Brake cleaner and don't touch where it is going to be applied. It will not delaminate. Also in passing if using it for carpet. Do not try to sew thru sticky back Dual-Lock. Use the Non sticky backed for carpet side. Sewing thru sticky back makes a mess. The 3" strip of the 400 takes a ton of pull to release.
