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-312don't need mixing and use directly.

Spreading

Spread ZJ-312 on base material with enough pressure and thickness not less than 1 millimeter.

Note

Full cure (dry 7 days under 20℃) for ZJ-312 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 ℃ and 35 ℃.

Paint Able Property

ZJ-312 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-312 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.
