SENSATIONAL SAND WATERBASED  URETHANE-ACRYLIC

 

GENERAL DESCRIPTION

 

Pruett-Schaffer’s #63-1 Sand Urethane is a very fast air-drying, self curing, water based, acrylic urethane coating.  It is designed as a low gloss, spray or roll applied finish coat for general equipment and flexible substrates maintenance applications. It exhibits good film hardness and flexibility, and excellent water, solvent, and abrasion resistance.

 

RECOMMENDED USES

 

This product is recommended for maintenance use  over various substrates including cold rolled steel, aluminum, plastics, composites, cement block and existing coatings. It will provide long term, cost effective protection against water, salt, oil, chemicals, and alkali cleaners.

 

SURFACE PREPARATION

 

At a minimum for acceptable performance, surfaces to be coated must be clean and dry, free of oil/grease, loose rust/paint, weld spatter, burning slag, dust, and chalk.  Feather all rough or sharp edges. Existing coatings must be tightly adhering.

 

 

Some well-cured existing coatings may need to be deglossed by sanding or abrasion for this coating to develop its best adhesion; test patches should be made to determine if adhesion is adequate.

 

THINNING

 

Add water slowly with constant gentle agitation to a maximum of 5% by volume.

 

APPLICATION EQUIPMENT

 

Air assisted or airless spray application is preferred. Use a .017-. 020 inch tip. May be applied by brush or roller.  Brushes should be of polyester or nylon construction. Rollers should have a nap thickness of 1/4 to 3/8 inch.  Apply to 4-8 mils wet film thickness (2-3 mils dry film thickness).

 

DRYING TIME

 

Dries set to touch in 30 minutes and dries hard in 1 hour at 77 0F and 55% R.H. Force drying ovens may be used, do not exceed 250 0F; allow 15 minutes minimum for flashoff of solvent before heating.

 

CLEANUP

 

Clean equipment with room temperature soap and water before the film dries.
