Product overview
Protective Film Adhesive GJ-8200 series is a family of solvent-based adhesives coated onto PE, PP, BOPP, PET, PVC and other films to make surface protection film. The core grades are ranked by peel level: GJ-8249 low adhesion at 10~100 g/inch, GJ-8220 middle adhesion at 50 ~ 450 g/inch and GJ-8235 high adhesion at 450~900 g/inch, letting film producers match the holding force to the surface being protected and the removal method.
Three specialty grades extend the range. GJ-8206 is the high-temperature grade with 500 ~ 800 g/inch adhesion and long-term resistance to 120 °C without glue residue. GJ-8203 is a thermolysis grade whose adhesion is high before heating and medium after heating, for films that must release after a thermal process. GJ-8207 contains added antistatic ingredients for antistatic protective films.
Solid content ranges from 30% to 40% and viscosity from 2000 to 12000 CPS at 23 °C depending on grade, so coat weight and drying can be tuned on standard solvent coating lines. The high-adhesion grades leave no residual glue and no ghosting on glass after long-term high-temperature exposure. ChemPortal supplies the GJ-8200 series in wholesale quantities to protective film manufacturers and converters.

Frequently asked questions
How do I choose between the low, middle and high adhesion grades?
Choose by the peel force the protected surface needs. GJ-8249 gives 10~100 g/inch for easy-release films on PE, PP, BOPP, PET or PVC; GJ-8220 gives 50 ~ 450 g/inch for nameplates and decorative parts; GJ-8235 gives 450~900 g/inch where the film must stay put in long-term high-temperature environments.
What are the solid content and viscosity of each grade?
GJ-8235 has 40% solids at 3000~7000 CPS; GJ-8249 30% at 2500~7000; GJ-8220 30% at 2000~7000; GJ-8206 30% at 5000~12000; GJ-8207 30% at 2000~6000, all measured at 23 °C. Values for the GJ-8203 thermolysis grade are provided in its technical data sheet.
Which grade resists heat, and will it leave residue?
GJ-8206 is the high-temperature grade, with 500 ~ 800 g/inch adhesion and long-term resistance to 120 °C without glue residue. GJ-8235 is also used in long-term high-temperature environments and leaves no residual glue or ghosting on glass. Both are solvent-based and coat on standard protective film lines.
How are these solvent-based adhesives supplied, and how do I get a quote?
