Material Notes:	GK-22R is one of the formulas specifically formulated for manufacturing “sticky pads” or “reusable Pressure Sensitive Adhesives (PSA)” with the liquid resin casting process. The cured products have stronger adhesion property than the other sticky pad formula we carry, GK-7. The material can be processed at near room temperature*, and can be manually processed for small batches. It can also be processed with an inline meter mixing equipment for high volume productions. The cured material is intrinsically sticky without the use of tackifier resin. The product can be applied to and removed from solid surfaces multiple times. A film made of GK-22R retains a sticky surface indefinitely. When the surface is contaminated with dust and oil, it can easily be washed with soap and water to regain the stickiness. The cured film is soft and flexible but fairly strong to resist cut and tear. The stickiness can be adjusted by blending part-B and part-C components. A higher part-B ratio makes a product with lower adhesion strength, a higher part-C makes a product with higher adhesion strength. After the ratio to make the desired adhesion level is determined, the part-B/C blend can be mixed with part-A to make the product. The chart on right is the adhesion properties of GK-22R and GK-7 made into various adhesion levels tested with our in-house test method. The value is “pounds of force to delaminate 1” x 2” area adhered to TPE film (as shown in the picture above). GK-22R has a higher adhesion strength range than typical sticky pad products used in cellphone holders and other common sticky pad products. The GK-7#2 in this chart is close to typical sticky pad products. #1 ---- 100: 0 = part-B : part-C 5.2 LBS #2 ---- 75: 25 = part-B : part-C 5.4 LBS #3 ---- 50: 50 = part-B : part-C 5.9 LBS #4 ---- 25: 75 = part-B : part-C 6.5 LBS #5 ---- 0: 100 = part-B : part-C 7.4 LBS (cohesion failure) Designations System Name: GK-22R Part-A: MPG-055 Part-B: PPB-174 Part-C: PPD-174 Mixing ratio: Part-A: Part-(B/C) = 30: 100 by volume Part-A: Part-(B/C) = 100: 312 by weight Information provided by Northstar Polymers
