fixing plastic locators to composite, help?
hi folks
i hand cut a company logo and a few letters using a band saw in composite and used Arldite to stick the plastic locators on the back. when i was fitting them one of the locators came off clean but the rest were perfectly fine. 🤔
the customer has just phoned and said one of the letters has fallen off could I pop round and refix it? of course i will, but i wanted to ask if anyone else has had this problem or what glue you use to do this type of thing. -

we buy ours in with the locators already fitted but in the past we have used some sort of black silicon adhesive to fix some in place for a job that had them missing.

We’ve always used Penloc 1:1R acrylic adhesive, for mounting snapfix to back of ACM letters.

I have always sanded where we put the locators and the back of the locator itself to give them a better bond, we use Indasol 2 part glues. I have had one or two failures in the past and these have been where the area was not sanded.

thanks lads, thats a great help.
it could be that we have not scored the surface but i would prefer to change to a different adhesive also, just to be sure it does not happen again. 🤨
at least now i have some options. -
I have always used the 3M two-part adhesive for bonding nylon locator fixings to composite.
I am sure its the 3M DP610 code which is for bonding plastic and painted metal.
I have tried some others over the years but found them brittle and that was just testing them in the workshop.As @CraigThompson points out, be sure to cross-score and clean properly before applying. it definitely makes a difference.
@Colin-Crabb-1 I haven’t tried Penloc or the Indasol version, but I would certainly give them a go as I have heard them recommended in the past. I might actually give them a go myself. Because I like the idea of the one that does not require nozzles or a gun to use it.
