CHO-SHIELD Primer 1091: CHO-SHIELD® 1091 primer is an air-drying liquid coating for enhancing the adhesion of CHOSHIELD 2000 series electrically conductive coatings and CHOBOND 2165 to chemically treated aluminum, and most composite surfaces. Using CHO-SHIELD 1091 primer prior to application of the CHO-SHIELD 2000 series coatings / CHO-BOND 2165 sealant ensures optimal adhesion to the substrate eliminating the possibility of re-work due to adhesion issues.

Typical Applications:

Application: For best bonding results, use the following application procedure: Thoroughly clean the chemically treated surface such as MIL-DTL-5541, Type II,

Class 3 chromate conversion with an appropriate solvent such as methyl ethyl ketone (MEK), isopropyl alcohol (IPA), etc. Air-dry for 15 minutes. Wet a lint-free cotton cloth with

CHO-SHIELD 1091 primer. Apply primer to the surface in horizontal and vertical strokes. Keep the surface wet at all times. After the entire surface has been coated, air-dry at room temperature for 1 hour or at 88°C (190°F ) for 30 minutes.

Note: If primed surfaces are not coated within 4 hours of the primer application, repeat the cleaning and primer application procedures, again, before coating. To eliminate the risk of an increase in surface resistance, only a light coating of the primer is recommended.
