hi

i have a 3mm aluminium sheet i want to glue to a mdf board.

what glues will hold this sheet inplace.

any suggestions???

liquid nails should work, or if the aluminium is mainly cosmetic then quickgrip will work

found a bostik product in the USA and NZ called Tuf as Nails. Looks perfect for my appication however its not listed on the australian site

Tuf as Nails is listed as a general purpose panel adhesive.

Bonds all common building materials. Perfect for bonding steel, aluminium and other materials to hardboard, plasterboard, cement sheet, timber or concrete. Bonds immediately on contact. Adds rigidity and stiffness, eliminates movement

that looks perfect for my appication. Maybe i should ring bostik and ask if this product is called a different name in Australia.

Sikaflex (the white one) available from Bunnings.

thanks for your help

ill go to bunnings and have a look at all the different brands

+1 for liquid nails. Once it's gone off, you'll never move it.

hope this 2c advice helps
the trick to a good lasting bond is
a) seal the MDF or get weather-resistant MDF/Ply
b) sand the matting surfaces so they are not smooth
c) keep weight on whilst glue goes off

as for product i would use surface adhesive. it doesn't harden as much as liquid nails thus allow for vibrations and expansion which is comon on our environment

liquid nails, silicone, or contact adhesive will all work fine for your purposes.

food for though, cabinet makers use liquid nails to glue ali/steel to chipboard or mdf.

Sikaflex stays flexible and is very strong but costs a bit more than the liquid nails. Sanding the back of the aluminium is a good tip though ^^^.

contact adhesive works well, so do pop-rivets (if you don't mind the bumps).

sikaflex is a brand, not a type of ashesive. go into bunnings and ask for sika and they will give you a pretty blank look. they make MANY types of ashesives, sealants, protectants and a crap load of other things.

just use liquid nails or a cheaper brand alternative. no need to get fancy pants with any high priced alternatives.

the only downside to liqui nails is it goes soft if it warms up, so its no good on panels that get hot

epoxy, some call it araldite... just make sure you scratch up the alloy side you want to glue to the timber or it wont bite, give that a go...

*shrugs* each to their own...

Rivets plus any of the already mentioned compounds FTW. What exactly are we doing anyway?

You won't find the temperatures in your car getting hot enough for liquid nails to sag or let go though.

+2 what george said.

We use a bostik contact adhesive for laminating colorbond. Never had a failure.
