Need help choosing a glue

[wavinwayne]

I have a pair of Bolle Parole sunglasses that I wear when riding my bike. About a year ago, I managed to yank one of the rubber nose pads off by accident. The nose pieces are
very, very soft rubber, glued onto two tiny little posts on the hard plastic frame of the sunglasses.

I used super-glue to re-attach the nose piece. The super glue has caused a rapid deterioration of the rubber. It is literally falling apart from the inside out. I can buy
a replacement set of nose pieces online, but I have no clue what I should use to glue the nosepieces back onto the frame. I don't want to use anything that will cause the rubber to deteriorate.

What type of glue/adhesive should I use for this? Keep in mind, the glue has to withstand huge, disgusting amounts of sweat from my head & up to 140°F heat, since they are frequently left in my car all day during the summer.

All recommendations are appreciated.

Clear 5 minute epoxy.

I'd use a flexible silicone adhesive, which will actually adhere to the silicone nose pads. The same kind of clear goop they sell for repairing tears in raincoats and for repairing sneakers should work. Sil-Poxy might be another option.

Ask the company who is selling you the replacement pair of nosepieces what type of glue. Also, you might be able to get them at a local optimetric shop and save the shipping/handling cost. The local shop may even install them for you as a courtesy.

Whatever you use clean the surfaces very well. Silicone adhesive works well with a large enough surface area, I have some 20 year old speaker stands made of concrete blocks that are held togther with silicone adhesive, but on small areas it doesn't seem to work as well. I like epoxy for a lot of stuff but it doens't always handle plastics well. Rear view mirror adhesive works well, weatherstrip adhesive does too, the latter being waterproof and designed for 'foam stuff'. Order some extra pads to try some different adhesives.

Thanks for the suggestions, guys.

I would opt for tinted contact lenses.

They protect eyes so well from dust, sand, insects and wind!

This topic should be made into a sticky.

I use Gorilla glue exclusively on everything now. You just have to know what it's going to do when it's dry and plan the amount you use accordingly. I've used it on everything from my daughter's headboard to fence posts to my car.

Polyurethane (Gorilla) glue does not work well on most plastics in my experience. Just about everything else though. I would second the epoxy.

GOOP
Use a tiny bit of GOOP glue, apply with the tip of a toothpick. It is waterproof, stays flexible, and is durable as all heck. It held a CV boot on an old car of mine together for about 1.5 years.

Do not use a polyurethane type glue (Gorilla or the Elmers equivalent). Polyurethane glues also react poorly to ling term exposure to sunlight, and can become brittle in my experience. They are fantastic for some applications, but this does not seem like it would be one of them.

 

[BrianWC]

In my experience with Gorilla used in outside applications and with the various poly crack sealers/gap fillers, they have discolored but their integrity has remained. But that's just my experience....

Half my fence boards are reinforced with Gorilla glue.

polyurethane glue is moisture curing, for best results both surfaces should be damp.

good superglue would do the trick.

 

[moribundman]

The only superglue that might work would be rubberized (flexible) and water-resistant superglue (Pink bottle Zap-A-Gap from your FHS). Unfortunately this C/A glue is black. If the nose pads are clear, this glue will look like ____. Regular C/A glue will dissolve when in contact with moisture (sweat) for a prolonged time.

+2 for epoxy or maybe a urethane glue. I have it for my shoes but I can't recall the name.

 

[moribundman]

Somebody please explain to me why epoxy would stick to silicone (most likely material for nose pads)? For crying out loud, you can cast epoxy and urethane resins in silicone molds without using any type of mold release because resin simply doesn't stick to silicone.

And as far as P/U glue like Gorilla Glue goes, it expands and looks like snot, no to mention it will also not adhere to silicone. Poor UV-resistance has already been mentioned.

DEVCON Clear Silicone Sealant should work.

worse than silicone is oil impregnated silicone from being in contact with skin

wavinwayne's replacement nose pads, if he decides to buy them, are brand new. Seriously, I would call Bollé and ask them for advice.
