Lock-Down Primer

Description

Lock-Down Primer is a single component, moisture-cured, low viscosity polyurethane primer designed to provide maximum corrosion protection, rust inhibition, and adhesion over steel, aluminum, and galvanized metal surfaces.

Sizes Available:

1 gallon (3.8 liter) can

5 gallon (19 liter) pail

55 gallon (208 liter) drum

Qualities

  • ADHESION: Its low viscosity allows it to penetrate and “wet” into weathered or sound rusted surfaces, imparting a tenacious chemical and physical bond between the substrate and subsequent topcoat.
  • WEATHERING: Rusted metal panels were wire-brushed, coated with Lock-Down Primer and “X” scribed to expose the metal. After 2,000 hours of accelerated weathering exposure, the coated panels showed no rust bleed, creeping or undercutting, or any deterioration of the product along the scribe lines.
  • Excellent Flexibility: The high ratio of acrylic resins contained in Acrylex 400 provide for maximum penetration and flexibility characteristics, as well as excellent cold temperature performance. It will not become brittle with age.
  • SALT SPRAY RESISTANCE: Rusted metal panels were wire-brushed, coated with Lock-Down Primer and “X” scribed to expose the metal. After 500 hours exposure to salt spray, the sample showed only minimal blistering and slight rusting along the scribe lines.

Uses

  • Lock-Down Primer is designed to provide maximum corrosion protection, rust inhibition, and adhesion over steel, aluminum, and galvanized metal surfaces. It is an excellent choice for use over sound rust on metal surfaces when sandblasting is not possible or practical.
  • Lock-Down Primer exhibits the unique ability to “wet” into weathered substrates, developing superior adhesion while resisting corrosive conditions, even when sound surface rust is present. Loose, flaking, or unsound rusted metal must be brought into sound condition or replaced.
  • Lock-Down Primer is an excellent primer for use under acrylic or solvent-based roof coatings and industrial finishes.

Compatible Substrates

  • Lock-Down Primer is designed to provide maximum corrosion protection, rust inhibition and adhesion over steel, aluminum and galvanized metal surfaces. It is an excellent choice for use over sound rust on metal surfaces when sandblasting is not possible or practical.
