Amercoat

495

Product Data/Application Instructions

High build, single coat protection High performance coating for new and existing equipment. High gloss, easily cleaned Good chemical and corrosion resistance Meets VOC requirements More flexible and abrasion resistant than conventional

epoxy coatings

The 100% solids characteristic of Amercoat 495 reduces thechances of pinholing and solvent entrapment at the substrate

coating interface, often a major cause of coating failure withconventional epoxies and lower solids systems.

Repair

1. Remove all rust, loose paint, grease or other contaminantspreferably by spot abrasive blast from damaged areasabraded to bare steel.

2. Remove contaminants from thin area and roughen surfaceif recoat time is exceeded. Apply Amercoat 495 as soon aspossible after surface is cleaned to avoid contaminants onthe surface.

SurfacePreparationCoating performance is proportional to the degree of surfacepreparation. Abrasive blasting is usually the most effectiveand economical method. When this is impossible orimpractical, Amercoat 495 can be applied over mechanicallycleaned surfaces.

Steel New steel without pits or depressions, SSPC-SP6.Previously painted or uncoated pitted steel, SSPC-SP10.Remove all loose rust, dirt, moisture, grease or other contami-nants from surface.

Aluminum Remove oil, grease or soap film with neutraldetergent or emulsion cleaner; treat with Alodine 1200,Alumiprep or equivalent or blast lightly with fine abrasive.

ApplicationEquipmentThe following is a guide; suitable equipment from othermanufacturers may be used. Changes in pressure and tip sizemay be needed for proper spray characteristics.

to achieve 105-120 at the gun

Surface temperatures must be at least 5F (3C) above dewpoint to prevent condensation.

Cure at50Fminimummaybe exposed to temperaturebelow50Fduringcure,butcure timewill be extended.

ApplicationProcedure1. Flush equipment with Amercoat 12 cleaner before use.

2. Mix each component thoroughly, to a workable consistency.3. Apply a wet coat in even, parallel passes. Overlap each pass

50 percent to avoid bare areas, pinholes or holidays. Crossspray at right angles if necessary.

4. Material temperature must be between 110 and 130F toachieve 105-120F at the gun.

5. Ventilate with clean air during application, between coatsand curing. Maintain air temperature to prevent conden-sation on coating surface.

6. Check film thickness using a wet film thickness gauge. Iffilm is less than specified, apply additional material.
