canopy Posted August 11, 2012 Share Posted August 11, 2012 I want to use Sikaflex 11fc to seal stainless steel that will be immersed in hot water. The Sikaflex label says to use a primer in this situation to make a good bond, but I have not been able to locate a store that carries such a primer. Is there anywhere worth checking that might carry a stainless steel primer? Link to comment Share on other sites More sharing options...
overherebc Posted August 11, 2012 Share Posted August 11, 2012 A sketch of the item would help. Also remember that stainless is used so that protective finishes are not really required so 'priming' would most likely be 'etching' to give a slightly rough surface to aid adhesion of the Sikaflex. Generally done by acid. A google search on 'etching stainless steel' will give you many answers. Cheers Link to comment Share on other sites More sharing options...
jombom Posted August 15, 2012 Share Posted August 15, 2012 OP did not say what type of hot water. If in doubt, make sure you use 18/10, which is resistant to chlorine attack. No primer needed. Unfortunately in Thailand people tend to use 18/8, because it's cheaper. Link to comment Share on other sites More sharing options...
