It is important to understand that
Dry Times indicated are
based on reference to a standard test procedure; normally ASTM-D1640.
This standard refers to various stages in the curing or drying
process under standard test conditions; some or all of which may be
listed. The stages (not necessarily in actual order) are Dry-to-Touch,
Dry-to-Recoat, Dry-to-Handle and Dry Hard. Unless stated
otherwise Dry Times are measured at 25o Celsius
Generally classified as
gloss, semi-gloss, satin, low-sheen
and flat this listing gives a non-qualified expectation of
the finished appearance of a product when properly applied.
Specifiers and users are advised that this stated property is a guide
only and does not imply a warranty of measured gloss or specific
range of gloss.
This property only relates to multi-component materials. Usually
expressed in the form 4 to 1 or 9 to 1 etc. the ratio
relates to the volume mix ratio of Base to Convertor.
This property only relates to multi-component materials. The times
stated are based on a standard test to evaluate the usable mixed life
of a relatively small mixed quantity of unthinned
material at the stated temperature (usually 25 degrees Celsius).
Higher temperatures will reduce pot life whereas lower temperatures
and thinning will increase pot life. The pot life duration includes
the induction time.
Recommended Dry Film Thickness
The figure(s) given in this section refer to
film thickness recommended per coat for the product in question; it
is not an absolute reference to a specified film thickness.
Often a product will have a range of common usage thicknesses in
which case that normal range will be indicated. The relevant
wet film thickness is also listed; this refers to the unthinned
This refers to the period over which a user can reasonably expect
paint materials to be stored and remain in a stable and usable
condition. Moderate settling and other storage changes may occur in
this period however, if stored as directed, the paint materials may
be expected to be easily mixed and homogenised. Some materials
(or individual components) have a stated limited shelf-life; users
are advised to rotate stocks and monitor batch numbers.
This represents the theoretical area that one litre of (mixed,
unthinned) paint will cover at the recommended dry film thickness.
Expressed in square metres per litre or m2/ltr
this figure is important to the applicator or estimator and is
inter-related with other properties such as volume solids.
This property relates to the original material or multi-component
mixture and gives valuable information to the user. Essentially the
quoted figure (60% etc) indicates the volume of solid
material (this makes up the cured paint film) as a percentage of the
original (mixed) unthinned paint. From this figure the applicator
can calculate, in the case of 60% volume solids that the
paint will cover a theoretical 6 square metres per litre at 100
microns or will require 100 microns wet film thickness
to achieve 60 microns dry film thickness.
