ASI Aquarium Silicone Sealant has been specifically formulated for the fabrication of fresh and salt-water aquariums. This high modulus component RTV Silicone Sealant forms strong cohesive bonds to glass without the need of primers. The bonds are unaffected by continuous immersion in water and, when fully cured, is non-toxic to fish. ASI Aquarium Silicone Sealant is a non-slump sealant and can be applied to vertical surfaces without flowing or sagging.High ModulusExcellent tensile strengthExcellent primerless adhesion to glassBond unaffected by continuous immersion in waterExcellent clarityBecause ASIAquarium Silicone Sealant is a 100% silicone sealant, it has excellent resistance to weathering including ozone, ultra-violet radiation and airborne chemicals.ASI Aquarium Silicone Sealant can be applied to surface temperatures from -18°C to +50°C (0°F to +120°F) and after curing, withstands constant operating temperatures from -57°C to +233°C (-70° F to 450°F).If you are a manufacture and you would like to see data on the ASI Aquarium Sealant to see how compared during independent testing, please contact us. We can also provide C of C or C of A?s with bulk shipments.MATERIAL PREPARATIONFor successful bonding, glass must be clean of all dust, dirt and oil. The presence of these contaminants may impede the development of the bond. Therefore, it is essential that the glass be cleaned with suitable and compatible cleansers such as nonoily solvents, diluted solutions of acetic acid or extremely hot water. The cleaned glass should be wiped dry immediately with a clean, lint free cloth or blown dry with hot oil free air.DO NOT clean glass with soap and water solutions. Soap residue can act as a release agent and result in adhesion failure.
