Clariant unveils ground-breaking additives

Clariant, a world leader in speciality chemicals, presented several new products developed by its Additives Business Unit at the European Coatings Show 2017. The company unveiled fire protection ingredients for intumescent coatings, an additive to improve properties of electrostatic powder coatings, a synergistic UV absorber/light stabilizer for solvent- and water-based coatings and a new family of waxes based on renewable resources.

Exolit AP 435 is a ground-breaking new halogen-free flame retardant that prolongs the shelf-life of water-based intumescent coatings without affecting fire protection properties. Coatings containing Exolit AP 435 have a low and stable viscosity, even in cold environments and after long storage, offering customers increased flexibility on the construction site. This fine-particle ammonium polyphosphate has the same high quality and performance level as Clariant’s well-known Exolit AP 422.

Exolit 855 (TP) fire protection ingredient for transparent intumescent coatings on wood is a completely clear, almost colourless solution, enabling it to be used even on light-coloured woods. It is suitable for application on surfaces subject to very strict regulations – in public buildings for example. As a liquid partial phosphoric acid ester, it can be used in combination with acid curing resins for coating solid and engineered woods (eg chipboards, medium density fiber boards (MDF), oriented strand boards (OSB), plywood and veneered wood).

AddWorks IBC 251 is a "tribo enhancing” additive for electrostatic powder coatings, providing an all-in-one solution for cost-effective formulations. It features a high electrostatic charge loading capability, together with protection against heat and light. AddWorks IBC 251 is suitable for a broad range of resins, including polyesters and polyester/expoxy binders, among others. It is non-staining, so discolouration is reduced under gas-fading conditions in open-flame baking processes.

Hostavin 1 TB-03 is a synergistic combination of a high performance UV absorber and a hindered amine light stabilizer (HALS). It meets the most demanding requirements for high performance coatings. Hostavin TB-03 is mainly characterised by its broad compatibilities in both solventborne and waterborne coatings (all-in-one solutions). It is recommended for all kinds of highly durable clear and pigmented coatings and for numerous applications, including automotive clear coats, plastic coatings, coil coatings, and high-end wood coatings.

Licocare RBW is a new family of hard waxes based on renewable feedstocks. Their diverse properties make them suitable for a wide range of applications including coatings and inks, polish and care, agricultural coatings and plastics processing. They show excellent matting, slip and scratch resistance properties in coating applications, and excellent rub resistance in printing inks. Licocare RBW 102 TP and Licocare RBW 106 TP are medium to high polarity wax types; Licocare RBW 300 TP is a partially saponified wax.
