To insure proper primer adhesion to the substrate, all contaminates must be removed. Depending on the type of substrate to be prepared, different methods should be used. There are a variety of processes to prepare these substrates for primer and painting.

Mixing Instructions

Shake primer component for 15 minutes before admixing.

Admix by Volume:

4 Parts - Epoxy Primer CM0483928
1 Part - Epoxy Adduct CM0120828

Add the Adduct into the Primer Component.

Admixed product should be allowed a 30-minute induction time for optimum application performance.

Reduce to sprayable viscosity using up to a maximum of 20% with CM0110944 Reducer.

It is recommended to strain admixed primer before placing material in containers for spraying.

Application

This product can be applied using conventional air spray, HVLP, Graco electrostatic airspray, or air assisted airless. Please consult your Sherwin-Williams representative for specific equipment settings.

Electrostatic users: Ensure that the aircraft is properly grounded for potential static buildup.

Equipment settings:

Best spray application results are obtained by applying one light continuous closed film cross coat.

Recommended dry film thickness is 0.6 – 0.9 mils (15-23 microns).

Surfacer primer can be applied after a MINIMUM two-hour cure to allow time for solvent flash-off. Thicker mil films or cooler conditions will extend the solvent flash time.

NOTE: Application of these product systems requires recommended temperature / humidity conditions and film thickness ranges. The material, hangar, and aircraft skin temperature should be no lower than 55°F / 13°C before, during, and after application.

Drying Schedule

Dry times are based on the dry film thickness of 2-3 mils (50-75 microns).

Air Dry Times (75°F / 25°C, 50% RH) To Apply Topcoat: Min. 2 Hours - Max. 72 Hours*
Tack Free: 5 Hours
Dry Hard: 8 Hours
Force Dry (140° (69°C), 45% RH) To Apply Topcoat: Min. 1 Hour

NOTE: Lower temperatures, heavy film thickness, improper activator range selection and poor air movement will extend the dry time.

Equipment Cleanup

Use clean Ketone–type solvents such as CM0110308 MEK. Do not allow material to cure inside equipment.
