This high performance, two-component, green corrosion inhibitive epoxy primer is intended for use on all types of aircraft. It yields films that are very corrosion, chemical, and impact resistant.
Surface Preparation

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.

Sherwin-Williams primers are designed to go over various substrate treatments. Before painting, please refer to the recommendations for cleaning, application, and preparation to the manufacturer of the treatment.

If a wash primer is needed, please refer to the Product Data Sheet for CM0484684 Wash Primer.

Mixing Instructions

Shake primer component for 15 minutes before admixing.

Admix by Volume:
1 Part Epoxy Primer CM0484900
1 Part Epoxy Adduct CM0120888

Add the Epoxy Adduct into the Primer Component.

For optimum application performance, stir well during a 15-minute induction time.

If a lower viscosity is needed, use up to 1 - 1 1/2 quart per 2-gallon kit of CM0110588 Slow Reducer, CM0702901 Fast Reducer, or a blend of both products depending on your shop conditions.

It is recommended to filter strain admixed and reduced 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:
Conventional air spray:
Air cap atomizing pressure: 50-60 psi (3.45-4.15 bar)
Pot pressure: 10-12 psi (0.69 – 0.83 bar) using a 60’ fluid hose (3/8” diameter)
Delivery Rate: 8-10 fluid oz (236-295 mL) per minute

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 1-2 hour cure to allow time for solvent flash-off. Please refer to the Product Data Sheets for Epoxy Surfacer (CM0560563, CM0480920, CM0482300, CM0487600) or CM0481810 Urethane Surfacer for more details.

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 55ºF / 13ºC before, during, and after application.

Drying Schedule

Dry times are based on the dry film thickness of 0.6-0.9 mils (15-23 microns).

Air Dry Times (75°F / 25°C, 50% RH)
To apply topcoat: 2 Hours min., Overnight max.

Force Dry (140ºF /60ºC, 45% RH):
To apply topcoat: 1 Hour min.

Light scuff sanding (320 grit sandpaper or Scotchbrite 7447) will be required for good intercoat adhesion if CM0484900 is allowed to dry overnight without applying an intermediate primer or topcoat.

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.

Shelf Life

Shelf Life is applicable only for materials stored in unopened and undamaged original factory filled containers.

Minimum Storage Temp: 40ºF / 4ºC
Maximum Storage Temp: 100ºF / 37ºC

CM0484900: 2 years
