Description: ASI 10.2 oz Clear Aquarium Sealant requires use of standard caulk gun for proper operation. Caulk gun not included. ASI Aquarium Silicone Sealant has been designed to aid in the fabrication of salt-water and fresh-water aquariums. This high modulus component RTV Silicone Sealant forms a strong cohesive bond to glass, without the need of primers. The bond is unaffected by continuous immersion in water and is non-toxic to fish once fully cured. ASI Aquarium Silicone Sealant is designed to remain in place, and can be applied to vertical surfaces without running, flowing, or sagging. Because ASI Aquarium 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 form -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). Material Preparation: Clean glass of all dust and debris, including oil and dirt. These substances could negatively impact the bonding of sealant to glass. It is recommended to use a compatible cleaner. Extremely hot water is acceptable. DO NOT USE SOAP WATER SOLUTION, which could leave residue resulting in bonding failure Thoroughly and immediately dry glass with a clean, lint-free cloth. Blow drying is acceptable
