DOWSIL™ Neutral Plus Silicone Sealant is a multi-purpose one-part neutral cured siliconesealant, designed for residential window and door filling and sealing, and residentialdecoration filling. Correct joint design minimizes stresses on the sealant, enables optimum sealant movementcapability, facilitates sealant application and minimizes the potential for sealant splitting andvoiding by enabling cure by-products to exit from the joint. 1. Minimum joint width of 6 mm.2. Minimum joints depth of 6 mm.3. For larger joints the width of the joint should be greater than the sealant depth,recommended the ratio of joint width to depth is 2:1.4. Avoid 3-sided adhesion: Apply backer rod or bond breaker tape in the base of the joint toensure the sealant is only bonded to the sides of the j Clean All Joint Surfaces:Substrate surfaces must be completely clean, dry and sound. Completely remove any loosedebris and/or old sealant. Since many materials have protective films, they need to becleaned with solvents such as toluene, xylene, methyl ethyl ketone, and banana oil.• For non-porous materials such as glass and aluminum alloy materials:Wipe the interface surface with a lint-free, white cloth and solvent to clean grease anddirt.• Immediately wipe again with another piece of clean cloth to completely remove anyremaining solvent and impurities from the interface.• Primer:Some materials may require a Dow primer to enhance adhesion to the material. Pleasecontact Dow for more information on Dow primer.Masking will ensure a clean, neat appearance and reduce clean up by protectingsurrounding areas from excess sealant. 1. Cut tip off the cartridge.2. Cut nozzle at 45° angle to the desired shape and size.3. Screw nozzle onto cartridge.4. Place cartridge in caulking gun. Air-operated or hand-operated caulking guns can be used.5. Apply sealant into the base of the joint so that it completely fills the joint, wetting bothsides. Do not simply lay a bead on the surface as the sealant will not penetrate the jointunder its own weight.
