Huntsman has coating chemistries covered at ECS 2015

Huntsman has announced its presence at the European Coatings Show (ECS) in Germany at the end of April. With four of its five business divisions present at this year’s ECS, Huntsman will demonstrate the full breadth of its coating capabilities – including a number of new innovations.
Huntsman manufactures a broad range of chemical products designed to drive performance in coatings and printing inks. Core technologies include:

• Intermediate chemistries for the building block stage of coatings formulation to influence production and physical attributes such as reactivity, water and chemical resistance, flexibility, toughness, viscosity levels and colour
• Additives that can influence coating characteristics, such as gloss, tint acceptance, opacity, rheology and durability
• Biodegradeable speciality anionic and non-ionic surfactants that can maintain a high conversion and stability and replace nonylphenol-based ethoxylates
• Speciality titanium dioxide-based solutions, colour pigments and barium sulphate additives to optimise the manufacture, performance, vibrancy and longevity of high quality, solvent- and water-based paints and coatings
• Off-the-shelf and customisable polyurethane raw materials, components and system solutions to boost the effectiveness of industrial coatings, such as polyurea and enhance the production and performance of adhesives and elastomers
• Epoxy resins, ambient and heat curing crosslinkers, reactive diluents and speciality additives that can enhance the functionality of high performance, solid, VOC-free, waterborne and multilayer coatings.

At this year’s ECS, Huntsman will focus on innovations that open up a world of opportunity for coating companies. For formulators looking to achieve precise pigment properties and colour characteristics, these include:

• Addipast and Carbofin carbon black dispersions
• Altiris infrared reflecting pigment and Reflect mixed metal oxide pigments to increase the solar reflectance of coloured coatings
• Blanc Fixe and Sachtoperse specialty BaSO₄ products for high-end coatings to improve pigment spacing and chemical resistance
• Colourplex inorganic pigments for demanding coating applications
• Deltio 81X pigment, a low-dust, free flowing pigment that can enhance weather resistance and improve whiteness and gloss
• Disperfin and Timbasol pigment dispersions for wood coatings
• Ferroxide iron oxide pigments for clean orange, red and yellow shades with good tint strength and purity
• Jefflink chain extenders to create colour stable polyurea, PU and hybrid spray elastomers and coatings
• FDA approved Solaplex yellow and orange inorganic pigments to replace traditional heavy metal pigments in indirect food contact (FCN 1252) applications
• Sachtleben RDIS, RDO and RDE2 and Tioxide TR50 titanium dioxide pigments for printing inks
• Tioxide TR88 titanium dioxide pigment for low-VOC and water-based paints
• Tintersol stir-in dispersions for decorative paints and industrial coatings
• Trans-Oxide transparent iron oxide pigments available in red, yellow and brown
• Easy to disperse Ultramarine TR pigments for the delivery of unique blue shades that offer optimum transparency and high strength.

Proposed changes to legislation have resulted in the need to replace Meko (Exkin 2 anti-skinning agent) in alkyd-based paint formulations. Huntsman is promoting its Exkin 100 oxime-based anti-skinning agent as an alternative to Meko that provides very good performance, without affecting overall drying time. Dr Brian Acklam will give a presentation at ECS on Meko replacement on April 21 at 11:30am on Stand 7-734 in Hall 7.
For formulators interested in perfecting priming procedures, Huntsman has developed a flexible, one-component MDI prepolymer for primer applications. Based on Huntsman’s proprietary Suprasec technology, the primer is a single solution for a range of substrates including concrete, steel and asphalt and can cover overlap zones and accommodate expansion and shrinkage caused by shifts in temperature, substrate moisture or load.

For complication-free curing Huntsman offers:

• Aradur 20315 curing agent, which exhibits good chemical resistance characteristics in all types of multilayer coatings used in moderate to warm climates
• Aradur 20317 aromatic-free curing agent – popular in the formulation of decorative floor coverings thanks to its mechanical stress resistance and very low tendency to yellowing and chalking: free of aromatics, and used in combination with liquid epoxy resins such as Araldite DY-T-1 and Araldite CY 184 resins, Aradur 20317 curing agent is suitable for the production of epoxy resin coatings
• Ethyleneamines used as hardeners in both ambient- and heat-cured epoxy systems and as an intermediate in a wide range of chemical products and resins
• Jeffamine polyetheramines – used as epoxy-curing agents and the building block of choice for countless coating applications including the creation of catalyst-free polyurea coatings.

For formulators focused on improving the environmental credentials of a coating, Huntsman also offers low-emission amines APDEA and DMDPTA for speciality coating creation; and Jeffsol alkylene carbonates – a solvent-based technology to replace toxic materials in paints, coatings cleaners.

At ECS 2015, Huntsman will also promote its latest adhesive and elastomer solutions. At the end of February the business launched its Vitrox Est next generation polyurethane resin system, which cures very quickly and can help in the production of high heat stable modeling, tooling and rapid prototyping boards. In September 2014, Huntsman also launched its Suprasec LM 4702 isocyanate-based prepolymer, which allows adhesive formulators to create bonding solutions with a free diisocyanate monomer weight content of below 1% – the threshold where H351 hazard or R40 risk labelling comes into effect. Unveiled at the trade fair FEICA, the solution is ideal for the creation of reactive hot melt (RHM) adhesives for book binding; box production; sports wear manufacture; the creation of automotive interior parts; and the edge banding and profile wrapping of items of furniture such as kitchen cabinets and work surfaces.
