The ultimate product to stick metal to metal is the unique CT1 construction adhesive and sealant. Tube, Pack of 1. Not all adhesives are alike -- wood glue and school glue, for instance, are designed for porous materials and would not work well on either metal or plastic. Wood can be a tricky surface to glue to metal because the two are so different in density and porosity. Use a damp rag to wipe away any glue that spreads or leaks onto other areas of the mold. Silicone does not have a problem with sticking to other materials but it is the PSA that might! Greater pressure than with polymers like nylon, HDPE, polypropylene, etc. $6.99 $ 6. Definitely recommend. The steps of the Process are outlined later down the page. To bond silicone rubber to steel; to bond silicone rubber to aluminum; to bond silicone rubber to metal Rough the surface of silicone rubber with sandpaper or steel wool. Wipe with isopropanol to remove any release agents. Firstly you need to understand that silicone does not stick to anything other than the adhesive system or the PSA (pressure sensitive adhesive). Kits include a sheet of adhesive for bonding silicone cord stock. So to answer the original question, silicone is not any more difficult to adhere to one surface than it is to another, it is the ability or not, due to surface energy, of any material to adhere to the PSA. Curing means letting it dry, and, although it is not necessarily a difficult process, it takes patience. Silicone to metal bonding has resulted in some unique and cost-saving designs. Why Adiseal is the best to glue metal to wood. Metal to metal glue applications usually do not involve as high heat as welding leaving the metal unharmed. Mechanical adhesion occurs when one substance -- in this case, silicone rubber adhesive -- fills tiny voids in a second substance, such as metal. With elastomers, pressure effectively increases the surface area area available to bond. Surface energy or interface energy, can be measured and if a surface has a low value then it will be difficult to adhere to.
