  • 400ml and 600ml sausage.


  • At 5~25℃ shady, dry place, 6 months of shelf life.


  • Surface preparation: Clean all dirty, dust, loose particles by steel brush and clean all oily things with cleaning agent. All former adhesive must be cleaned out by scraping, paring, friction, jet of strong air or suitable ways.

Paintable Property

  • JS-336 could be painted after dry with traditional method like epoxy or acrylic paints. The adhesive surface will take place reaction and soften if using high solvent content coating like luster enamel or high oily base coatings.
  • Coating should have similar tensile strength compared with adhesive in order to get best appearance and property. Painting could be processed after 24 hours if thickness of adhesive is less than 3 mm while painted after 48 hours if thickness more than 3mm.

Handling Precautions

  • JS-336 is not easy inflammable.
  • Not contact sealant with food or cosmetics; Not put sealant out of children
