May 1, 20233 yr Good morning all. I'm going to be using FM330 foam as an intermediate around my Upvc windows and leaning towards finishing with Compriband TP600 on the exterior edge but depending on overall cost I might use an lmn silicone. So my question is are any Lmn silicones compatible over the FM330 or if any at all being they could react with the foam. Thanks all
