Our research has led to the development of rapid drying conductive adhesion promoters (CAP’s) with improved adhesion of powder and liquid coatings to nonconductive substrates such as MDF, particle board, trim board, wood plastic composites, fiber reinforced composites, ABS, Polycarbonate, Noryl GTXTM, SMC and Polyolefinics etc.; while at the same time improving transfer efficiency by dissipating static charge. The ability of our CAP technology to dry quickly permits application in a continuous/conveyorized production line followed by the application and curing of powder and liquid coatings. The use of CAP’s in this process eliminates the need for preheating, plasma treatment and chemical etching of plastic substrates while improving both film appearance and application efficiency. UV curable as well as LTC (low temperature cure) powder and liquid coatings can now be applied uniformly even in recess areas/faraday cage areas. This patent pending technology utilizes novel conductive materials in conjunction with a polymeric adhesion promoter and at the same time improves flexibility and interfacial adhesion along with anti-static properties.
Conventional treatments used to enhance surface conductivity utilize quaternary ammonium salts dispersions (QAS) which render the coated substrate conductive, but moisture sensitive as the QAS conductive treatment are water sensitive and migratory. Lastly, QAS technology does not enhance adhesion and flexibility.
component polymeric penetrant which can be applied with
or without surface preparation over clean or lightly corroded
steel/aluminium (no sand blasting or chemical treatment
needed). The coating contains unique Nano-sized reactive
materials which first penetrate the rust and scale to its
morphological depth and then migrate to the non-corroded
metal surface. Once the particles penetrate to metal surface,
they polymerise and completely encapsulate and arrest
the rust by forming a highly crosslinked network that is
impervious to moisture and corrosive salts. The coating forms
a long-lasting chemical and physical bond with base metal.
Results over cleaned pretreated steel surfaces can exceed
10,000-hour salt spray with no blisters or scribe creep when
top coated. Many coatings for use in refinery or off shore
applications are comprised of three layers, which may include
75 to 150 microns of a zinc rich primer, 25 to 35 microns of
an epoxy primer and 60 to 100 microns of a two-component
urethane topcoat. The new innovative technology described
herein provides a signifcant beneft in terms of 1) improved
performance, 2) elimination of the epoxy primer coat and 3)
material and labour cost savings as the primer is applied at
100 to 125 microns and the topcoat at 75 to 100 microns
