Primer 28 (Rigid or Flex)

Quick Overview

Primer 28 is a one-component primer used primarily for concrete substrates and other inherently dust prone applications. It is available in Rigid or Flexible formulations. It is a moisture-cure solvent based polyisocyanate which is reduced 3:1 using Xylene, Naptha Aromatic 100, Butyl Acetate or MEK. This primer may be also formulated with zinc to provide galvanic protection when used in industrial metal assemblies. It is ideal for polyurea or polyaspartic topcoats which require high performance adhesive characteristics. It is normally used in demanding environments such as coastal marine, industrial chemical processing and oily water treatment plants where superior adhesion is required. Top-Coats include SuperSkinSytems’ polyurea coatings as well as other top coating systems such as uethanes, enamels or acrylics. If application surface retains extensive corrosion, normal forms of media blasting is recommended to create a secure surface preparation. PRIMER 28 is applied in thin coats and quickly flashes off to a dry-tacky touch in minutes depending on relative humidity and temperature. If the primer becomes totally dry or exceeds the max working application window of 24 hrs then a quick recoat will be necessary. Top coating must be applied to the primer while in a tacky wet to tacky dry state.
