Lord Fusor 108B question

[Bow Tie 67]

Does anyone have experience using Fusor 108B on Aluminum and or in a high heat situation?

I'm thinking of adding aluminum brackets to an AFCO radiator so I can re-use the 4th gen dual fan assembly. I'm sure the adhesive will be strong enough, but I'm not sure if the heat from the radiator will be a problem.

Yes I know the tabs can be welded but I have the Fusor adhesive and would like to use it.

Thoughts?

I don't think it's a good idea, most bonding adhesives will break down or soften up and fail at 400 degrees, spend $20-50 and have a shop TIG the brackets on

that product is def not the right application. However that does not mean that there is not an adhesive that will work. Here is what I recommend.

It has an operating temp range of -50 to 300 deg f since its on a radiator I assume you wont be peaking over 250?

Matt heres the specs from the Fusor MSDS sheet, Fusor away boiling point of 642 F I think you will have other things to worry about if this stuff fails

9. PHYSICAL AND CHEMICAL PROPERTIES
ODOR: Mild BOILING RANGE: 642 °F - 642 °FAPPEARANCE: Black VAPOR PRESSURE: N.D.
PHYSICAL STATE: Paste VAPOR DENSITY: Heavier than Air
ODOR THRESHOLD: N.D. EVAPORATION RATE: Not Applicable
SOLUBILITY IN H2O: Insoluble DENSITY, LB/GL: 15 lb/gal
pH: N.A. VOLATILE BY WEIGHT: 0.00 %
FREEZE POINT: N.D. VOLATILE BY VOLUME: 0.00 %
COEFFICIENT OF WATER/OIL

just fyi

this is the material saftey data sheet, not a technical datasheet on material properties. that boiling point only applies to the material before it is mixed together. once it is cured it will not boil, it will flame out, and the flame out point has nothing to do with the operating temp range of the adhesive before failure. that company does not specify a hot tensile lap shear stength. that is the specification that will most directly apply to this application. the product i mentioned has over 3000psi shear strength in that parameter. not to mention it is designed to survive thermal stress cycles as would be seen in a cooling system. before i said anything about the adhesive that the OP mentioned i researched it. fusor does not specify specific cured strength properties of that material. therefore i cant say if it would work or not, because they dont give enough information to make an educated decision.

Just mock it up, mark the locations and have someone weld it up for you. Its not worth "giving it a try" with the adhesive. Most of the adhesives arent designed to do what you want.

Just do it right the first time.

Well,the adhesive TheCntrion posted will work in OP's application just fine. The problem is he would have to buy it. Fusor stuff on the other hand will eventually fail.So, I agree,mock up the brackets and have them welded,it might be cheaper than buying adhesive.Having a piece of mind knowing that they are on there welded for good is much better than broke on the side of the road with damaged radiator

Thanks for the info gentlemen I'll make sure I weld them and find another use for the fusor.

Didn't think of thus before but the point came up.... By the time you buy the right adhesive that you can count on with that heat etc, it would probably be cheaper to just have someone weld it

very true
