QY-8000 Screen Printing SMT Adhesive is a kind of single epoxy resin adhesive Designed for screen printing. Good stable curing shapes without stringing, overflowing and slumping are achieved even at a super high speed and longtime printing. Because of the “rarely cutting” bonding strength and very low humidity absorption, it is specially fit for SMT technology of porous printing in common temperature. Its shape can easily be controlled. We can not only expect a long-term preservation stability but also the excellent thermal resistance and electrical properties. Moreover it is good for environment protection for its safty, no solvent and no smelling.

Very good stable curing shapes without stringing and slumping are achieved at super high speed dispensing and very amall dots. 4. stable adhesive strength can be obtained with a variety of SMD. 5. Long-term preservation stability is expected. 6. High heat-resistivity and excellent electric properties are possessed. 7. Usable for screen printing. |
（Curing condition）
○Recommended curing condition:Over 150 sec after PCB’s surface temperature has reached 150℃.or over 180 sec after PCB’s surface temperature has reached 120℃.
○When the higher curing temperature and the longer curing time,the stronger adhesive strength can obtained.We would suggest you to search out an optimum curing condition,for the temperature exerterd on the adhesive may occasionally vary according to the size,material,etc.of component parts mounted on PCBs. |
（How to use）
○Adhesive should be preserved in refrigerator(2-5℃)to keep on its quality.
○Before processing,the adhesive should be taken out from the refrigerator for de-freezing about a few hours until it reaching the room temperature. ○The bottom of printing screen should be cleaned timely for good printing shape. ○Toluene or ethyl acetate is possible to use for cleaning up this adhesive. |
（Warning）
○Warranty:6Months.
○Store adhesive in a refrigerator keeping the temperature at 2-5℃
○This product may cause skin irritation to sensitive personnel.
○In case Seal-glo QY-8000 gets in touch with skin,wash it thoroughly with soap and water.
○In case of eye contact,wash out with clean water and consult a medical doctor immediately.
