Detailed product description
OTTOSEAL® S 730 is based on a neutral-curing oxime system and is completely MEKO-free. The high water vapour permeability enables professional exterior sealing in line with RAL guidelines. Thanks to its excellent UV, weather and ageing resistance, the joint stays stable in the long term. The sealant is fungicidally formulated, non-corrosive and ideally suited to demanding building connection joints.
Application tips: Clean and dry the substrate and prime if necessary. Apply the cartridge evenly, smooth the joint and make sure there is sufficient backing material. Apply only within the recommended temperature range.
