Pigments for Outdoor Coatings Applications: What to know
There are so many types of outdoor coatings applications: roofing, architectural, industrial equipment, road markings, coil coatings, and so many more. Because they’re all exposed to weathering, there is an expectation that the paint should last a long time. There are slightly different criteria that you should be aware of when choosing a pigment for different types of outdoor coatings. Two popular outdoor applications – industrial and architectural – are outlined below.
1. Industrial Equipment.1 This industry (including Agricultural, Construction & Earthmoving) is trending towards coating finishes that have both a greater visual appeal and enhanced durability. This is of course dependent on the outdoor performance requirement of the product being coated. Polyurethane coatings have been widely used for high-performance coating applications, offering excellent resistance to abrasion. With the advances in resin technology, these second-generation polyurethane coatings offer even more benefits, including “overspray melt-in”, which is particularly helpful when spraying huge areas such as agricultural harvesters. Powder coatings are also becoming increasingly popular for agricultural equipment and require high performing pigments. These coatings are corrosion resistant and can retain gloss and colour with only one application, while remaining cost-effective.
Bismuth vanadate pigments are often recommended for industrial applications because of their excellent weatherfastness. However, they are not as high in colour strength, so they are often mixed with clean, bright shade organic pigments. These include benzimidazolone yellows and oranges (ie. PY.151, PY.154, PO.36) or phthalocyanine blue and green pigments (ie. PB.15:1, PG.7). These are not only great for mixing colours, but pigments with these chemistries offer excellent light and weather fastness, as well as chemical resistance. This creates a brighter, more durable finish for the customer.
2. Housing Exterior. There are many types of substrates used in architectural applications – wood, brick, stone, concrete and more! While it depends on the type of siding you have, the general rule of thumb is to paint the exterior your house every 3-7 years (whether that is the garage, windows, siding, etc.).This can be a hassle and takes time and money to complete, so you want to make sure it is going to last as long as possible. Different pigments must be used depending on the surface being painted.
Wood Coatings: Wood coatings are very common worldwide. Most of these paints are water-based. These pigments must demonstrate excellent light and weatherfastness, as well as chemical and heat resistance. Some of the most common types of pigments used for exterior house paint are inorganic iron oxides or CICPs, whether it is a yellow, red, brown, black or green pigment. Most home owners prefer these colours because they have a more acceptable cost and higher performance (including exceptional resistance) compared to organic pigments.
Concrete Coatings: Coloured concrete coatings are becoming increasingly popular in European countries. Alkali stability is extremely important when applying paint to a concrete coating as well as high PVC architectural coatings and stucco applications. Pigments that are not optimized for alkali stability may cause potential degradation of the paint colour if the substrate has not fully dried. Furthermore, pigments for concrete coatings applications need to have durability, solar reflectance, hiding power, and high colour strength. Suitable pigments for concrete coatings include: PY.154, PY.194, PO.36, alkali stable BVs and CICPs. Our most popular pigments for this application are our new line BV pigments (DCC Yellow 2GTAA, 3GMXA, RMXA), as they offer the best alkali stability in the market.

3 Quick Tips to Ensure You’re Optimally Dispersing a Pigment in Coatings
DCC LANSCO’s highly knowledgeable Field Chemist, Lucy Gibbons, has over 10 years of experience in the chemicals industry. Today she shares 3 key methods to ensure you’re always dispersing a pigment in coatings effectively & efficiently
A high-quality dispersion requires the following criteria:2 lowest possible viscosity for the required pigment loading, good hiding power, consistency in colour, resistance to flocculation and a stable shelf life. To achieve these criteria, consider the following:
- Achieving Optimal Shear.
To disperse a pigment in a dispersion and develop its color fully, it must undergo a process called grinding.3 The ease in which a pigment is dispersed varies; some require more shear and others less. Shear plays an important role during the dispersion process, as a significant amount of shear energy is required to fully wet out, disperse and stabilize a pigment dispersion. Too much or too little shear can damage the pigments particles or other materials such as fillers or additives. The colour of a pigment depends on a specific particle size distribution. Too much shear can cause the pigment particles to fracture due to the surface abrasion, which can negatively affect the overall colour of the end-product (shade becomes dirty) and its performance properties. Too little shear and the pigment with not achieve full colour development and affect the final shade and tint strength. The level of shear must be controlled to avoid these issues
- Selecting the right additives.
There are several types of additives that can be incorporated into the dispersion process. The first step in the dispersion process involves adding a wetting agent to the mixture, followed by a dispersing agent. The former lowers the surface tension of the liquid while the latter helps prevent flocculation (when particles stick together).4 There are also other additives that perform a specific function such as de-foamers (reduce foam levels in dispersion), as well as drying agents (if using a medium oil). Ensuring the right additives are selected is critical, as it could be very costly to re-disperse an entire batch.
- Ensuring full dispersion.
As mentioned, the pigment particle size distribution needs to be within a certain range to create a stabilized pigment dispersion and avoid flocculation. Once the pigment is optimally dispersed, it needs to be evaluated. The most commonly used test to do so is the Hegman scale (also known as a grind gauge). This gauge is metal block with a series of small parallel grooves on it. The grooves decrease in depth from one side to the other and uses “Hegman units” to determine the particle size. To get a reading, paint is applied at the top of the grind gauge and is then scraped downwards with a metal applicator. The paint fills the grooves on the device and looking closely, you can tell the size of the particle. For stir-in or encapsulated grades, DCC LANSCO uses a close-mixer test at 1000 rpm and records readings every 5 minutes to ensure it is fully dispersed.

Conferences in September – What is coming up?
Next month, we have the OCCA Centenary (September 12-13) and CAD RETEC (September 23-25) conferences. Here we give you a sneak peak of two abstracts being presented by our staff at these conferences!
OCCA Centary Conference 2018
At this year’s Oil and Colour Chemists Association (OCCA) Centenary conference, DCC LANSCO’s Peter Carey-Yard will be presenting a paper on the developments in bismuth vanadate pigments. Make sure you attend this presentation at OCCA for more details!
Recent Developments in Bismuth Vanadate Pigments
Author: Peter Carey-Yard, Market Development Manager (Coatings)
Abstract: From their invention in the mid 1980’s the demand for Bismuth Vanadate pigments has steadily grown. Their highly chromatic shade combined with excellent opacity and durability attracts usage in a wide range of coating applications including automotive, powder, coil, and high-performance industrial coatings. In architectural coatings Bismuth Vanadate has become the preferred choice for the yellow colorant used in exterior coatings.
The subject of this presentation will focus on the significant improvements made to this class of pigment recently. Pigment developments have enhanced the opacity, chroma, expanded the colour space and significantly increased the tinting strength & chemical stability whilst providing improved cost effectiveness. In 2016 a new Bismuth orange (Pigment Orange 86) was introduced to the market.

Organic pigments: How environmental and regulatory challenges shape the present and our future
Author: Nigel Smith, Global Technical Service Manager & Product Manager (Dispersions)
Abstract: This paper will provide some insight into the environmental and regulatory pressures which are impacting the availability and economic sustainability of many of the core pigment chemistries that form the base of color chemistry in the polymer processing markets.
Most of today’s key color chemistries are manufactured using raw materials sourced from Asia, which has traditionally lagged behind the west with regards to regulatory and environmental constraints. As the developing economies introduce tighter environmental controls then the availability of the intermediates has reduced, prompting increases in prices and variability in the quality / consistency of the key raw materials used to make many organic pigments. Natural disasters and explosions / fires have affected other suppliers, compounding the overall shortage of quality raw materials in the market. Pigment manufacturers are constantly innovating to deliver consistent, high quality, pigments to minimize the impact of variable quality and supply throughout the raw material supply chain. Legislation to reduce emissions has been in place for some years, but new standards are always being implemented and the drive to meet and exceed the latest foreseen regulations defines the suppliers who will continue to service an ever more demanding industry.
This paper will detail the impact these challenges have on a variety of high performance & traditional pigment chemistries, highlighting the current and future issues that need to be addressed to ensure compliance and sustainability.
