Corrosion Resistance of Hardcoat Aluminum with Hot Water Seal
Q. I need an expert opinion on some P1020 Aluminum that will be embedded in concrete. I need the surface to bond to the concrete but I also need it to be corrosion resistant. I have spec'd a Type III class 1 with a note that surface needs to be bondable, do not use surfactants. The last time I had this done by a local house they did not seal the hard coat. Will this significantly effect corrosion resistance? If I have them use a Deionized hot water seal, will this effect bondability? Any info will be greatly appreciated.
