Conklin Encase™ Primer

Rust Inhibiting Metal Primer

Product Description

Conklin Encase™ is a versatile and effective water-based, rust inhibiting metal primer that is suitable for use on a broad range of interior and exterior metal surfaces. It produces a unique effect of penetrating into rust and expelling air. This makes it useful for application on non-rusted as well as rusted metal surfaces.

The primer is formulated for use in combination with Conklin’s Rust-Off™ Rust & Oxide Remover. Well-cured Conklin Encase™ serves as a primer for the application of the following top coats with early recoats providing the best adhesion:

  • Benchmark™ Acrylic Latex Roof Coating
  • Equinox™ Acrylic Latex Roof Coating
  • Rapid Roof™ HV Acrylic Latex Roof Coating
  • Rapid Roof™ III Acrylic Latex Roof Coating
  • PUMA XL™ Urethane Modified Roof Coating
