Product Description
CSL 343 is a one-part, neutral cure, room temperature vulcanizing (RTV), 100% silicone sealant. It is ideally suited for window and door manufacturing where extreme joint movement is a design or specified requirement.
CSL 343 readily extrudes and cures to produce a low modulus silicone rubber building joint seal. The low modulus characteristic minimizes strain on the substrate surface and the good elasticity allows excellent recovery from compression and extension.
