PVC Adhesive

[equitiman]

Hello again,

Sorry but I'm almost done with all of my annoying questions... I have purchased a nice new shiny rubrail to compliment my nice new two-part poly paint but I am not sure which adhesive to use to glue it on. I want something permanent (no chance of removing this thing anytime soon). The rubrail is made out of PVC and I seem to remember reading somewhere that polyurethane is not compatible with PVC as it will attack this type of plastic. I was thinking of using Sikaflex as one variety says it is good for mounting rubrails, but it is a polyurethane sealant??? What am I missing here?

Thanks!
Bob

IIRC, polyureathane-based adhesives/sealants won't attack PVC... Polysulfide-based adhesives are very agressive and attack most plastics across the board. Should be fine using a polyureathane based adhesive with the PVC IMHO.

Thanks SD,

I must have been getting polyurethane and polysulfide mixed up.
