GENERAL INFORMATION

PHYSICAL PROPERTIES

APPLICATION

Water-Bake is a water based acrylic-melamine modified enamel. This coating is designed to meet all state and local air pollution compliance regulations. Water-Bake is engineered as a direct replacement for standard solvent-borne bake enamels. It is an ideal coating to use wherever compliancy is mandated.

Apply Water-Bake to metal substrates that have been properly cleansed and pre-treated, either iron phosphate for steel or yellow or clear chromate for aluminum. It is also excellent on zinc-plated/cadmium plated steel, commonly associated with the electronics industry.

Water-Bake cures at a baking temperature of 275í-300íF for approximately 20-30 minutes.

This formula is custom-matched according to your specifications, and is capable of being textured using standard air-pressurized spray equipment. It is also available as a self-texturing, single step application. Gloss range is 0-75í using a 60í gloss meter.

See MSDS for further information about health, safety and storage guide.

CLEAN UP: Clean all equipment as soon as possible with water.

CAUTION: Avoid Freezing; if frozen allow to defrost at room temperature.

Physical & chemical tests were done on "Q Panel R-46 I" steel panels, iron phosphate.

Adhesion tests were performed on appropriate substrates.

Application Recommendations- use conventional air pressurized spray equipment: stainless steel is highly recommended.

BASE COAT-

Fluid pressure of 15-20 PSI, Approx.

Air pressure of 50 PSI, Approx.

Viscosity: #3 Zahn cup 17-22 seconds @77íF

Reduction: A 5-10% reduction with tap water is necessary.

*Note: Viscosity adjustments by use of Zahn Cup may be misleading due to the thixotropic nature of this formula. Reduction by a volume ratio of paint to water is recommended for consistency.

Apply smooth coat: If texturing, allow minimum 15 minutes flash-off or pre-bake 5 min@275íF. If smooth finish coat is desired, flash off 15-30 min. And bake @275í-300íF for 20-30 min.

TEXTURE COAT-

Fluid pressure of 10-15 PSI, Approx.

Air Pressure of 5-20 PSI, Approx., depending on texture pattern desired.

Viscosity: Use same as base coat or increase according to texture pattern.

Flash-off: 15-30 minutes after texturing; depending on ambient air temperature and air movement.

BAKE CYCLE

Flash-off: 15-30 minutes (pre-bake base coat 5 min. @275íF)

Bake times: 20-30 min @275í-300íF

NOTE: There is a direct relationship between increased air temperatures coupled with air movement, and shorter flash-off times.

Strategic placement of fans and heat will help eliminate extensive flash-off times, especially during humid days.
