  • fixing plastic locators to composite, help?

    Posted by Peter Cassidy on April 17, 2024 at 3:07 pm

    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. ๐Ÿค”
    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. ๐Ÿคจ
    at least now i have some options.

    @Peter-Cassidy

    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.
