In order to extend the life of
process equipment’s, are there key
considerations (from the end-user)
when selecting the appropriate
paint and coating?
Coating selection is a specialized task
and requires knowledge of multiple
engineering disciplines as well as
a thorough understanding of the
requirement of intended applications.
Apart from ensuring that the surface
finish of the material to be coated
is properly prepared, the effect of
temperature and pressure on coating’s
adhesion and permeability are just few
key selection parameters to be primarily
evaluated. The electrical properties of the
coating are also a factor in the selection
process in certain applications.

pipelines and storage tanks, there are
practical and cost effective technologies
available that keep the surface of the
coating clean from debris and deposits.
In a given environment, if the coating
surface is not kept clean, corrosion can
develop under the deposit and debris and
the protective role of paint and coating is
severely compromised.

What are the plans for the future,
from the industry stand point?
The paints and coatings industry can
be categorized into three sectors which
are: (i) decorative and architectural, (ii)
general purpose industrial and (iii) special
purpose coatings. All the three sectors
have their own needs, requirement and
future projections. Some of the common
requirements of the 03 sectors could
be listed as (i) faster application and
preference of single layer rather than
multiple layers, (ii) short curing time,
(iii) improved chemical and abrasive
resistance, (iv) ‘smart’ properties such as
self-healing or ability to transmit certain
electrical or thermal signals as well ability
to dampen those signals for defense
application.

From your viewpoint, what are
the high-level best practices you
typically propose?
I would greatly emphasize that coating
selection to be carried out by individuals
having the required knowledge and
expertise of material properties and their
behaviours in various environments.
What are some best practices
you can offer end-users in the
areas of design, specification
and maintenance of paints and
coatings to ensure their long-term
performance?
To ensure long-term performance, the
foremost and important step is to select
an appropriate paint and coating for the
application. Economic factor also comes
into consideration in coating selection
in view of the anticipated designed life
of the equipment to be coated. A very
importance parameter in ensuring long-
term performance of coatings is to keep
the coating surface clean as practical
as possible. With specific reference to
