Wacker 121 Clear Aquarium Sealant 

Wacker 121 Clear Aquarium Sealant is a one-part, acetoxy high performance silicone sealant for construction of aquariums.  This aquarium sealant cures at room temperature in the presence of atmospheric moisture to give a permanent flexible silicone rubber.  Wacker 121 Clear Aquarium Sealant exhibits excellent primerless adhesion to most non-porous siliceous materials (e.g. glass, tiles, ceramics, enamel, glazed tiles); metals (e.g. aluminum, steel, zinc or copper); impregnated, varnished or painted wood; and some plastics.
