    3M windshield urethane-gctid807893

    I understand that 3M windshield urethane is used to bond the glass to the car.

    that means it is more than adequate to handle the high summer temps of car

    sitting in the sun.

    I want to glue some light weight stuff to my dashboard and also my interior-side of my

    windshield. but, everything falls off in the summer sun.

    would 3M windshield urethane be a sure way to gitRdone, permanently?

    Have you tried double faced foam sticky tape (3M) ?

      It would be fine but is a bitch to work with. VERY thick and difficult to squeeze from the tube without an electric caulk gun, and is like the proverbial tarbaby. But it does work well and like 5200 will stick to almost anything except starboard.

      3m exterior trim tape, "the double side foam tape" works very well as long as the object is not very heavy. It's used to hold all kinds of things to the exterior of a car, mirrors, trim, emblems, rocker panels, taillights, etc.

        Depending on what you are mounting 3M VHB tape is very good and is used in semi-structural applications.

          Oh yea - someone already touched on it but if you think 5200 is bad to work with the black windshield urethane is worse.

          With 5200 you get to 90% clean with a thinner rag and all is mostly well. Get to 90% with that crap and you have smeared black gunk all over and now you get to really start cleaning.

            When using gooey adhesives, blue masking tape is your friend. Use it copiously and save on the clean up headaches later. Your project may even look like it was done by a pro.

              Thank ya'all so much!

              i did not know about VHB and how it is used. I will try that.

              Note: I researched 3M VHB and I assume it is a high grade of

              double sided foam tape.

              I learned that this following product when used with 3M VHB

              will make an amazing *super* strong bond:

              3M 06396 Automotive Adhesion Promoter

              Related question: can ya'all speculate on success of

              mounting a small lightweight object (like an iphone as an example)

              to a car dashboard using 3M 5200. ?

              I'm afraid to "try it" because it is a biatch to get that stuff

              off (should it not be up to the task of permanently mounting

              something and standing up to the hot summer temps found

              on a dashboard)

              I use 5200 quite often.

                Unfortunately while 3M 5200 is a very good product, heat will facilitate it's removal. So from what I have learned about it from BOC, it is unlikely to work on the dash of your car or boat if it is subjected to high surface temperatures. There are high heat products out there, but I don't feel qualified to comment on them since I have not used them much except on mechanical assemblies.

                    thanks, that's why I lean toward the windshield adhesive because that is the only thing holding the windshield (not through bolted or screwed) and it takes a heat without loosening and dropping the windshield. I get that it IS nasty to work with.

                      Tape is a part of the solution but that stuff is a bigger PITA than anything else I have ever worked with. And more often than not my work does look like a pro did it. B)

                        kwb, sorry to hear of the trouble it causes you. It is tricky stuff to work with and far from my favorite. I finally figured out that I was applying way too much product. Once the quantity was reduced drastically I had better success. And some do turn out looking pretty good. Wish I had taken pictures to show you what I mean. Just a little too much can make a big mess, and not enough results in failure. Like I said, not my favorite stuff to use.

                          Urethanes are not uv stable, similar to most adhesives. The sun will come through the back of the glass and destroy the bond by degrading the glass side of the urethane. You need to shield the other side of the glass from the sun or use a silicone based product like dow corning 795, it seems to have good adhesion and sticks to plastics fairly well.

                            Urethane can not be exposed to direct sunlight it will break down and crumble apart. That's why the edges of a widshield are black to block the sun.

                              I use this stuff on a weekly basis installing Aircraft windshields.

                              If you want to use the 3M 590 adhesive to mount something to a windshield you will need to use 3M 590 glass primer. It is a UV blocker and will protect the adhesive. After applying the primer let it dry for about a 1/2 hour first. Best adhesion occurs within 2 hours of primer application.

                              If applying the adhesive to anything other then glass use 3M 591 all purpose primer

                              Before applying anything use 3M AP596 Cleaner/Adhesion promoter. Let dry for 15 minutes before applying primer.

                              I have used this stuff to glue all sorts of stuff together and if done properly i bet you could glue a boat together with it.

                              I have about 10 tubes some one can have if you want to drive to me to get it.(expired from work but still very usable)
