    摘要: A multi-purpose primer for painting applications for both interior and exterior usage acts as both a thermal insulator and a flame retardant for substrates and surfaces in industrial, commercial, military, and residential buildings and structures. The primer includes a plurality of hollow microspheres that shrink to a tightly-packed layer as the primer dries, and a flame-retardant additive, to provide an insulating, protective barrier. The primer produces a high quality, white-pigmented acrylic sealer which reduces heating and cooling requirements and costs. The primer is also a Class A-certified paint that retards flame spread by forming a burn-resistant layer that slows the spread of flames to insulate the underlying substrate and surface from fire.
