After Js-316 cures fully, it can be bepainted by traditional way, including epoxy resin and crylic acid coating. The high solvent ingredient such as enamel or high oil in coating will make sealant reactive, leads to soft surface.
To achieve best performance and appearance, the tensile strength of coating must match Js-316. To the thickness less than 3mm, bepaint after 24 hours, to the thickness above 3mm, bepaint after 48 hours.
11. fireproofing: Js-316 is not inflammable.
12. First aid measures
