ZJ-311 Polyurethane Sealant for Windshield Glazing

Description ZJ-311 is one-part room temperature curing polyurethane adhesive with good adhesion property. It reacts with moisture in the air to form a kind of elstomer with high strength, aging resistant, vibration exhaustion resistant, low temperature resistant and corrosive resistant properties. Where to use Direct glazing and sealing for windshield glazing, glass fiber reinforced plastic fittings, installation in automotive, accessory, auto steel and aluminum board. Characteristic Fast tack free High adhesion strength Neutral Good chemical corrosion resistance Good water proof Paint able One part no mixingexcellent 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 result Test method 1 Appearance Black, gray, white, brown paste Black, gray, white, brown paste By eyes 2 Tack free time, Min 20-60 40 Touch 3 Curing rate,mm/24h ≥3 3.0 100*10*12triangle 4 Solid content,% ≥96 98.1 GB14683-1997 5 Specific gravity, g/cm3 1.2±0.1 1.2 GB14683-1997 6 Hardness, Shore A 55±5 58 GB/T531-1997 7 Tensile strength, Mpa 8±1.0 7.3 GB/T528-1998 8 Elongation at break,% ≥500 520 GB/T528-1998 9 Shear strength, Mpa ≥4.0 5.1 GB/T7124-1986 10 Tear strength, N/mm ≥20 26.8 GB/T529-1999 Packaging 300ml aluminum cartridge, 12 cartridges /carton 400ml and 600ml sausage, 20 sausages /carton Storage At 5oC 25oC 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 Primers may be required to achieve optimal adhesion. Smooth priming base and no permitting primer clump and uniformly disperse to prevent any coating cumulus. Mixture ZJ-311 don't need mixing and use directly. Spreading Spread ZJ-311 on base material with enough pressure and thickness not less than 1 millimeter. Note Full cure (dry 7 days under 20oC) for ZJ-311 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 oCand 35 oC. Paint Able Property ZJ-311 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-311 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.
