Cnhybond945 primer developed from our company is a kind of halogen-free clear light brown liquid with low odor. It can be used to promote adhesion of double sided adhesive to surfaces such EPDM, TPU, PVC, polyethylene, polypropylene, ABS, PET/PBT blends, concrete, wood, glass, metal and painted metal surfaces, especially with Acrylic Foam(VHB) tapes, the bonding effect will be better. Feature:speed up free tack time, promote the adhesion Surfaces of bonding materials:PP,EPDM,TPU,PVC,ABS,PET/PBT/Blends, Concrete,Wood,Glass,Metal and so on. It can replace 3M PT869,3M AP111, 3M AP115 Tape primer/adhesion promoter. Primer 945 can be used for the frame joint of Touchscreen phone, tablet, GPS navigator, and resistors and so on. Typical Physical properties and Performance Characteristics Note:The following technical information and data should be considered representative or typical only and should not be used for specification purposes Solids Approximately 5%-8% Color clear light yellow Flash point -4℉(-20℃) Net Weight 750-800grams per liter Viscosity 10±5cps Application Techniques Surface preparation: The bonding surface must be relatively clean and dry.Contaminated surfaces should be cleaned with a 50/50 Isopropyl Alcohol and water mixture,A clean lint-free cloth should be used. Application: Shake CNHYBOND 944 primer well before using: 1. Apply a thin uniform coating to the bonding surface using the minimum amount that will fully coat the surface, allow cnhybond 944 primer to dry thoroughly before applying tape. This is usually accomplished in 5 minutes at room temperature, Be sure the primed surface remains free from contaminants prior to applying the tape. Porous surfaces may require 2 application of CNHYBOND 944 primer for uniform coverage and good adhesion.. 2. Allow first application of primer to dry before applying the second coat, CNHYBOND primer 944 may be applied with brush or swab, It can also be applied with a pressurized flow gun, knurled roller or other similar type of application equipment Clean up: Cnhybond 944 primer can be removed with isopropyl alcohol,Vigorous scrubbing may be required Shelf life 1. 12 months from date of manufacture when stored in the original container at 15-27℃ 2. Keep cnhybond tape primer 944 in the original container 3. Keep original container tightly sealed to avoid solvent evaporation
