TRILAC - 747
Water Base Lacquer |
|
Description:
Trilac - 747 is a water-born, air-drying, clear lacquer recommended to use on all type of metal surface, especially copper, Brass, Silver, Zinc & Cadmium or Aluminum. Trilac - 747 dries to a bright, crystal clear finish, which provides tarnish and corrosion resistance.
Advantages:
- Non-flammable, very safe to use.
- Excellent corrosion and tarnish protection.
- Excellent adhesion.
- Excellent solvent resistance and humidity resistance.
- Hard, bright, crystal clear finish.
- Air dries rapidly.
- Reduces energy consumption.
- Lowers clean-up coast.
- Excellent water resistance.
- Good to excellent resistance to salt spray test.
- Good to excellent stain resistance.
Operating Conditions:
- Trilac - 747 is supplied "READY-TO-GO" and can be sprayed using a conventional air or airless spray equipment.
|
- To reduce the viscosity, use only tap water up to 50, depending on the thickness required and the shape of the part.
|
- If foaming occurs during the mixing with water, allow to settle or skin off the surface before using.
|
- Immersion time is 5-10 seconds and usually dries in air in 15-30 minutes. For fasterdrying, heat up to 180 F. Parts may be dipped WET since the lacquer is water soluble; however, the parts should be rinsed thoroughly before lacquering. The dip tank should be lined with a non-rusting material such as Stainless Steel, Fiberglass or Polypropylene
