Is polyurethane stronger than silicone?
Silicone caulk is far superior to polyurethane for certain applications. It adheres very well to almost any material but it does not adhere well to wood surfaces. Also, silicone caulk is not paintable, so be careful about where you use it. The silicone in the caulk prevents the paint from bonding with the caulk.
Are polyurethane and silicone the same?
The primary difference is at the chemical level. Polyurethane is an organic material. Silicone is an inorganic material. The effects of breakdown of silicone and polyurethane depend on the sealant's chemical makeup.
Is sealant and silicone the same?
