Düsseldorf, GERMANY – Huntsman Pigments & Additives has launched ALTIRIS® W400 pigment – a brand new, near
infrared reflecting TiO2 pigment that can improve the thermal stability and durability of white, bright and light colored
plastics used in exterior applications such as window and door profiles, sidings, decking, soffits and fascias. News of the
development of ALTIRIS® W400 pigment comes ahead of K2016 – where the business will promote the new solution.

ALTIRIS® W400 pigment is the most recent introduction to Huntsman’s popular ALTIRIS® pigments portfolio, a family of
products designed to deliver enhanced solar reflective properties across a broad color palette. Available for use in cool
white, near-white, bright color and pastel shade plastics, the patented ALTIRIS® W400 pigment is unique in terms of its
combination of large crystal size, narrow particle distribution, high crystalline purity and dense silica coating.

With a primary crystal size of 400nm, the product consists of a macro titanium dioxide (TiO2) core, dense silica shell and
alumina outer coating with an organic treatment. This larger crystal size shifts the reflectance emphasis across the solar
spectrum. This ensures that a greater proportion of near infrared light is reflected when compared to a typical grade of
titanium dioxide produced for pigmentary use – while also helping to maintain substantial hiding power and tinting
strength.

Tests show that, compared to ordinary TiO2, the spectra of ALTIRIS® W400 pigment can boost the solar reflectance of
white and light colored plastics by as much as 25%. This in turn can enhance the thermal stability, weather resistance
and durability of final products where the effects of light and heat exposure are known issues.

Light colored plastics incorporating ALTIRIS® W400 pigments will typically deliver lower heat build up temperatures than
plastics made using conventional TiO2 – a significant advantage in the exterior plastics market where every extra degree
of heat protection counts. With greater heat resisting properties, plastics heat more slowly, reach lower maximum
temperatures, show a smaller temperature difference through the substrate, and consequently experience lower
temperature drops in the evening. Ultimately, that means less expansion and contraction, less product warp, and exterior
plastic products that will last longer, particularly in hot, sunny climates.

The launch of ALTIRIS® W400 pigment comes as interest in solar reflective solutions continues to grow across the
plastics industry; new legislation – designed to improve the solar reflectance of construction materials and the overall
energy efficiency and longevity of buildings – is driving demand. Russell Evans, Business Development Director at
Huntsman Pigments & Additives, explained more:

Solar reflective pigments for exterior plastics applications have been around for some time and there has always been
strong support for the concept of passive cooling. Yet until recently the technology was an optional item in the plastic
formulation toolbox. That’s now starting to change. For example, in some countries, new buildi ng standards are coming
into force and specifiers are now actively searching for solar reflecting pigments to build into their product ranges to
improve performance and durability. As decision makers seek to maximise reductions in infrared, heat-related plastic
warping, we are seeing a real need for a fully optimized reflective technology. As such, the launch of ALTIRIS® W400
pigment – a patented 400nm, dense, silica coated macro TiO2 product that can help improve the solar reflectance of even
the most reflective plastics – is incredibly timely.”

ALTIRIS® W400 pigment is very easy to use. With an alumina coating and organic treatment, it is engineered to disperse
quickly in plastic formulations. Used as a direct replacement for TiO2, ALTIRIS® W400 pigment has the same processing
and storage parameters.

Other products available in Huntsman’s ALTIRIS® pigment range include ALTIRIS® 550 and ALTIRIS® 800 pigments,
which are designed for use in mid and darker colored plastic surfaces, where solar heat management can have an even
greater impact on long-term weatherability.

For more information about ALTIRIS® W400 pigment, or if you have a plastic project that would benefit from the use of a
solar reflective pigment, please contact the Huntsman team, who would be happy to arrange a meeting either before,
during or after K 2016: p&a_info@huntsman.com
