JOINLEADER 688 Aquarium Silicone Sealant is a high-performance sealant designed for the construction of aquariums and high-quality glass structures (Total Vision Glazing, TVG).
It is also suitable for use in glazing and industrial applications and for the construction of silos and containers.
It may be applied by hand or machine to seal a variety of substrates such as glass, coated glass, ceramic tiles, enamel, painted surfaces (wood and other), aluminum, steel and many plastics. In some cases, metal and plastic substrates require priming before JOINLEADER 688 Aquarium Silicone Sealant is applied.
12 months in unopened packaging in a cool and dry storage place at temperatures between +5°C and 27°C.
