ZJ-316 Polyurethan-Dichtstoff

Description ZJ-316 is one-part room temperature curing polyurethane with high adhesion strength, good elasticity, aging resistant, vibration exhaustion resistant, low temperature resistant and multi coatings paint able and easy application properties. Where to use Maintenance and sealing for auto windows, it also be used for the direct for auto windows. Characteristic Fast tack free High adhesion strength Neutral Good chemical corrosion resistance Good water proof Paint able One part no mixing excellent weather proof, aging resistant property Abrasion able excellent noise, vibration and Impaction resistant Damp resistant No sagging Anti mildew Technical Data(for reference) No Item Standard Test method 1 Appearance Black, gray, white, brown paste By eyes 2 Specific gravity, g/cm3 1.2±0.1 GB14683-1997 3 Hardness, Shore A 45-55 GB/T531-1999 4 Sagging No By eyes 5 Tack free time, Min 25-60 By touching 6 Curing rate,mm/24h 2-6 100*10*12 triangle 7 Shear strength, Mpa ≥3.5 GB/T529-1999 8 Tensile strength, Mpa ≥4 GB/T528-1998 9 Elongation at break,% ≥300 GB/T528-1998 10 Modulus at 100% elongation, Mpa 1.2-2.2 GB/T528-1998 11 Tear strength Mpa ≥8.0 GB/T529-1999 12 Solid content,% ≥96 GB14683-1997 Packaging 300ml aluminum cartridge ,12 cartridges/carton 400ml and 600ml sausage.,20 sausages/carton Storage At 5 oC 25 oC shady, dry place, 6 months of shelf life. Technical Service Full support for customer in Technology Application 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. Priming Commonly no need for primer. Primer could be recommended in order for best performance. If using primer, smooth priming base and no permitting primer clump and uniformly disperse to prevent any coating cumulus. Mixture ZJ-316 doesnt need mixing and use directly. Spreading Spread ZJ-316 on base material with enough pressure and thickness not less than 1 millimeter. Note Full cure (dry 7 days under 20 oC ) for ZJ-316 should be finished before applied place permits water entering into. The adhesive surface could be painted but no recommendation for solvent based paints such as colorful enamel. If should be used, please do in site testing to prove compatibility. No permission for wet spreading tech. NO recommendation solvent, water, cleaner or soap solution. No permission for high chloride content disinfected area like swimming pool before consulting Zhijiang's technician. Application temperature is between 5 oC and 35 oC. Paint Able Property ZJ-316 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. Anti Fire ZJ-316 is not easy inflammable. Health and Safety No contact with eye or skin. Please contact doctor or poisoning preventing center in case of poisoning. If contact with skin, clean thoroughly 15 minutes long or look for doctor. Pretest Process Zhijiang will sample all related material and do testing to decide best adhesive type and best performance to preventing any potential problems. Please ask for Zhijiang's technician for more specifics.
