Skin formation: 5-15 minutes
Curing Rate (2mm/h): 10-12
Kastar 735 Acetate Aquarium Silicone Sealant is a one-part, organic silicone-based sealant for aquarium equipment. It adopts an acetic acid curing system and the product has very good water-resistant performance and it has a good performance when exposed to an outdoor environment. Once fully cured it ends up being a very strong elastomer that is extremely adhesive to glass and most aquarium substrates. This product has also passed through environmentally hostile environmental conditions and does not possess B fail hazardous material. After they have been cured they are harmless to fish and aquatic life forms. The product does not fade and can be used indoors and outdoors, non-affected by humidity, and can take constant pressure of water. This is one ideal sealant for use in the closure of fair equipment such as aquariums and glass tanks.
