What is a good glue to use to glue aluminum to foam?

Answer 1

Poly-Bonder.

Directions for Bonding Polyethylene using a poly-bonder.

Flame Treat:

1. Fit a propane torch with a flame spreader.

2. Following the operating cautions of the propane torch, ignite the flame.

3. Observe the flame in a darkened room, noting the primary (bright blue) and secondary (faint yellow) portions of the flame.

4. Adjust the flame so that the primary flame is contained within the spreader, and the secondary flame is 1-1/2" beyond the spreader.

5. Treat the polyethylene to be bonded with the tip of the secondary flame by passing it over the polyethylene in 5 gentle strokes. Total exposure to the flame should be 2-3 seconds (.5 seconds per stroke). This light exposure should not deform or melt the polyethylene in any way.

6. Test the polyethylene for bond readiness by wetting it with water. If the water runs off immediately, the treatment was not effective. If the water sheets-up on the surface, the surface is ready for bonding. If unsure, compare the water's action on the treated area with an untreated area.

7. Bond joints within 1 hour after treating. Always prepare test bonds to be certain that flame treating is effective with your material. By using the method for preparing a glue joint of Polyehtylene as described below, it has been established through shear testing by the manufacturer that structural bonds nearly exceeding the strength of the polyethylene can be achieved. Those bonds registered 1,950 Psi in lap shear testing of HDPE.

To achieve similar results, be sure to follow the next three steps:

1. Leave room for the glue. Don't squeeze all of the glue out of the joint when clamping, if you do, the bond will fail. Instead, cut small bits of fishing line and drop them into the glue before clamping.

2. Clean and roughen the parts. Rough parts hold much more glue and form mini-shear joints. Always apply glue to bond pieces to be bonded to properly wet the surfaces.

3. Mix the glue thoroughly. This glue appears to be mixed almost instantly, but requires at least two minutes of mixing.

Answer 2

JB Weld provides a Med strength Bond a long full cure time but proves a very solid bond this would unsuitable for joints that will take alot of stress.

Epoxy even when both sides are sanded can some lose if the joint is struck. There is a Aviation Glue you can get from a specialst supplier that is extremely good but also quite expensive but provides a very soild seamless join.

Answer 3

I would probably use spray adhesive. It holds well and does not bleed through like liquid glue would. It grabs on contact so you can not reposition the cloth once it is put down.

I personally would use a mechanical fixing alone (screw) or avoid doing it altogether especially if the material is exposed to the elements (you do not mention). The reason being is the thermal expansion of the two materials will be at different rates and stretching and warping may ensue.

UV rays and heat from the sun may also damage the glue over time.
