NANTO PAINT TECHNICAL PAPER PUBLISHED IN THE JULY/AUGUST ISSUE OF EUROPEAN COATINGS JOURNAL
Technical paper on “Cost effective corrosion barriers” has been published in the July/August issue of "The European Coatings Journal".
This paper describes the advantages, possibilities and characteristics of novel epoxy nanoclay composites. Small quantities of functionalised nanoclays hold great potential for the performance of conventional paint systems. Exfoliation, chemical compatibility and orientation are critical to enhance the barrier properties, resulting in improved corrosion resistance and fire retardancy. The novel coatings discussed in this article entail that a variety of different substrates can benefit from these properties.
Three questions to Roberto Cafagna, Nanto Paint CEO:
1. What are the most common fields of application of nanoclay next to anti-corrosive and fire-retardant coatings?
Nanoclay is commonly applied in industrial assets of heavy industry. There are oil and gas, marine, high value infrastructure and energy. Other very common fields of application of nanaclay are the automotive and aerospace sector as well as business to consumer coatings such as electronic, high abrasion resistant coatings, UV resistant coatings and high barrier coatings.
2. How much did the electrical resistance increase?
In case of a primer, which is 80 microns thick, the electrical resistance increases from 9x107 to 5x10 Ω/cm2.. For the intermediate, which is 150 microns thick, it grows from 2x1010 to 8x1011 Ω/cm2.
3. What are the best methods to ensure that nanoclay is properly exfoliated?
The best methods are a surface treatment that is compatible with the matrix and high shear mixing
