Does Lightfastness and Weatherfastness Data Accurately Reflect the Performance of Organic Pigments for Outdoor Applications?

Jadel Baptista (Technical Director, DCC LANSCO)

We are frequently asked about the expected performance of organic pigments for use in outdoor applications. Typically, formulators refer to lightfastness and weatherfastness data and in many cases they are not even sure of the difference between the two.

Does Lightfastness and Weatherfastness Data Accurately Reflect the Performance of Organic Pigments for Outdoor Applications?

The short answer is yes; however, you must be careful. It is important to understand the difference between two concepts - Lightfastness & Weatherfastness.

Lightfastness is the pigmented coating’s resistance to change upon light exposure while being exposed under a glass cover. The glass cover eliminates the potential environmental impact of variables such as moisture, humidity, and acid rain.

Weatherfastness is the pigment’s resistance to change upon exposure to sunlight including outdoor environmental factors such as temperature, rain, humidity, etc. Understanding the differences between lightfastness testing and weatherfastness testing makes it clear as to why weatherfastness data is the appropriate reference for outdoor/exterior pigment selection.

“Most all pigments with a good weatherfastness rating will also have a good lightfastness rating; however,

not all pigments with a good lightfastness rating will have a good weatherfastness rating.”

For the most accurate UV Performance testing, DCC LANSCO strongly encourages customers to evaluate the pigment or pigments in their polymeric system, processed under their processing conditions and tested in an environment the most closely duplicates the exposure of the finished product. DCCL is here to help you with the broadest range of pigments available for the most demanding applications.

Understanding why weatherfastness data is the appropriate reference for outdoor/exterior pigment selection, the next question typically is: Can weatherfastness data accurately predict the outdoor/exterior durability of a pigment in a given polymeric system?

The answer is to this question is no. In order to accurately determine the outdoor/exterior durability of a given pigmented system, the actual pigmented system needs to be tested under the actual conditions of use and final application. The reasoning for this is as follows:

• There is no “bullet proof” correlation between acceleratedweathering and natural exposure. A common rule of thumbis 2000 hours of Xenon Arc exposure is equivalent to 2 yearsoutdoor exposure. This is a general reference; however, oneshould also consider additional variables.

• A pigment’s weatherfastness is not a constant, it can beinfluenced by the processing/dispersing conditions, thepolymer chemistry, additives and extenders, and the Ti02/pigment concentration levels. Other things to consider:

a. Application elevation (higher means more UV)

b. Application location (nearer to the equator meansmore UV)

c. Application exposure to natural element levels,such as wind, moisture, and temperature.

d. Application weather variations can cause varyingdegrees of degradation for the same time periodat the same location.

e. Application seasonal periods. There is significantlyless short-wave UV-radiation during winter.

f. Application angle of exposure (angle of incidence,cardinal direction)

g. Application insulation (outdoor samples withinsulated backing can degrade up to 50% fasterthan uninsulated samples)

h. Equipment Program Cycle variations with respect totime, light, and moisture.

i. The Spectral Power Distribution (SPD) of the artificiallight source

j. Cycle temperatures (increased temperature equalsincreased degradation)

k. Substrate selection can influence heat and moistureretention

Colour is essential to human experience. From

pre-history, through ancient civilization into the

modern era, cultures have strived to create colour

in the objects around them. Early peoples exploited

natural resources to create images from their

surroundings, such as red earth, black soot and

white chalk. With time people developed more

sophisticated techniques to refine minerals to

generate a wider palette with blue, green, bright

red and yellow. Often toxic in nature, these early

inorganic pigments formed the skeleton of the

pigment manufacturing industry. With the discovery

of coal tar in the 1800s, and the ensuing rapid

industrialization of synthetic chemistry, an explosion

of colour transpired, leading to the modern chemical

industry. The historic generation of plastics followed

a parallel path, beginning with use of natural

materials such as ivory and tortoiseshell. Progression

to processing of natural materials such as rubber,

cellulose and shellac to generate more functional

plastics, evolved to a place where coal tar chemistry

provided a natural next step. This culminated in the

discovery of Bakelite, the first fully synthetic plastic

in 1907, which ignited the imagination for plastic

materials, and the widespread production of

consumer and industrial items accelerated. Colour

and plastic developments went hand in hand, as

by the 1950s the desire for brightly coloured,

functional items sky-rocketed. Pigment chemistries

were re-imagined with this new era in mind and

from this point colour effects were generated

specifically for plastic functionality. Textile fibers,

automotive parts, plastic bottles, packaging and film;

all un-thinkable now, without the effect of colour.
