Product Details

DOWSIL™ 121 Structural Glazing Sealant is a neutral-cure, RTV silicone sealant ideal for repair or replacement of structurally glazed glass and other substrates. It is equally suitable for on-site structural glazing – including storefront systems or attachment of panel stiffeners – as it is for in-shop structural glazing.

The material is supplied in a two-part cartridge in which the catalyst is a smooth, white paste and the base is tinted either black or grey. It can be used in deep, narrow joints to obtain a complete cure.
