CHO-BOND Primer 1085 & 1086: Parker Chomerics CHO-BOND primers 1085 and 1086 are air-drying liquid coatings used to improve the adhesion of Parker Chomerics CHO-BOND conductive silicone compounds to metal and other non-silicone substrates. The primers are moisture reactive and clear in color. CHO-BOND 1085 primer is formulated to achieve maximum adhesion on non-silicone substrates for CHO-BOND 1029 adhesive. CHO-BOND 1086 primer is formulated for use with CHO-BOND 1016,1030, 1035, 1038, 1075 electrically conductive adhesives/sealants and CHOTHERM® 1641 thermal compound.
Note that typically, the proper primer comes bundled as a “kit” with the CHO-BOND or CHO-THERM compound ordered. However, if extra primer is deemed necessary, then part numbers for just the primer are provide in the ordering information below.
For best bonding results, use the following procedure:
1. Surfaces to be joined must be clean, dry and oil free. In a well-ventilated area, clean the substrates with isopropyl alcohol (IPA) and let the solvent flash off. (Other solvents, such as methylethyl-ketone (MEK), toluene, or acetone can be used to clean difficult to remove contaminants).
2. Wet a lint-free cotton cloth with the primer and apply to the surface in horizontal and vertical strokes. Keep the surface wet at all times. A cotton swab is a common applicator for a grooved or stepped surface. NOTE: Due to the low flash point temperature of the primer, ensure that the container is re-sealed immediately after use. 3. The primed surface must cure for 30 minutes at room temperature. A relative humidity of 40% to 70% is optimal. A low humidity level may require a longer cure time. NOTE: There is no elevated temperature cure time for the primer. 4. Apply the CHO-BOND / CHOTHERM adhesive / sealant per that product’s instructions.
NOTE: If the primer has been applied for more than 4 hours without the application of the adhesive / sealant, repeat steps 1 through 4.
