CW: What types of
performance enhancing
additives does your
company offer?

BASF: BASF offers a wide variety of UV light stabilizers namely Tinuvin® UV absorbers and hindered amine light stabilizers to protect coatings from harsh UV radiation from sun for an extended period and preserve the life of the coating. Tinuvin® family of light stabilizers help in preventing change in color or yellowing, delamination, degradation, cracking and blistering while maintaining the gloss of the coatings exposed to radiation from the sun.

Borchers: We offer cobalt replacement technology (Borchi OXY-Coat), highly engineered dispersant technology as well as some unique rheology modifiers.

Clariant: Clariant is a globally leading specialty chemicals company, based in Muttenz near Basel/Switzerland.

It offers a large variety of performance
enhancing additives specifically for the
paints and coatings industry, with solu-
tions for all major coatings segments such
as Architectural, Protective & Marine,
Transportation, Wood & Furniture,
Industrial and Packaging, and also for
printing inks.

Their broad scope of performance enhancement ranges from adding protective effects such as improving heat, light and weather resistance to reduce color fading and loss of gloss, to flame retardants with a preferred environmental and health profile for intumescent coatings, processing waxes lending functional end-appli-cation benefits and specialty ingredients such as APEO-free wetting agents, label-free dispersing agents, sugar-based neutralizing agents, as well as silver biocides for antimicrobial preservation.

Key technologies include surfactants, polyethylene glycols, polyether amines, emulsifiers and polyethylene and mon-tan-based waxes.

Dow Coating Materials: Dow Coating
Materials offers a broad and robust port-
folio of performance enhancing additives
across a range of chemistries, including
rheology modifiers, wetting agents, sur-
factants, slip/mar additives, dispersants
and defoamers. Our wide variety of solu-
tions offer improvements in paint appear-
ance, ease of application, and stability
and provide benefits in areas including
slip/mar resistance, water resistance, low-
ered VOC and wetting, among others.

keim additec: Surface modifiers in the form of Ultralube® water-based wax dispersions and emulsions, Ceralene® solid and mju:wax® micronized waxes and non-wax-based SILCO dispersants, flow/ leveling agents and defoamers.

Lonza: We offer additives to protect coatings from microbial attack, both in the liquid state during manufacturing and distribution and in the dry state after application.

Micro Powders: Micro Powders offers the most comprehensive range of micronized waxes and surface additives available. Our precisely micronized fine powders provide surface protection (mar/ scratch/abrasion resistance), gloss reduction, water repellency, tactile properties (texture/soft touch), and special effects (colored powders).

Shamrock Technologies: Shamrock Technologies offers slip additives including PTFE, waxes, wax blends, compounds, dispersions and emulsions. This month Coatings World interviewed a number of key suppliers of performance enhancing additives. These include: Avinash Bhaskar, transportation coatings segment manager, Dispersions, Resins & Additives – North America, BASF; Laura Bittle, sales and global marketing director at Borchers; Silvia Ziebold, global marketing manager industrial applications and

Tobias Niederleitner, global technical segment manager BU Additives at Clariant; Thomas Polaski, field marketing manager – architectural coatings and Yujie Liu, technical service scientist at Dow Coating Materials; David Grabacki, president of keim additec surface USA; Scott Brown, global technical manager, materials performance and protection at Lonza; Rich Czarnecki, technical director at Micro Powders Inc.; Joon Choo vice president of Shamrock Technologies; and Scott VanRemortal, technical sales manager at Unimin.
