Innovative additives for paints and varnishes in the form of 3M Dyneon PTFE Micropowder or 3M Novec fluorosurfactants are being presented by the Advanced Materials Division of the multi-technology company 3M for the European Coatings Show from 19 to 21 March in Nuremberg (Hall 7, Stand 7-212). The range of products on show will be supplemented by 3M Dyneon PTFE Dispersions and further additives, such as Glass Bubbles and Ceramic Microspheres plus surface finishes for glass and ceramics (Easy Clean Coating).

For over 30 years now, 3M Dyneon PTFE Micropowders used as additives in paints and dyes have been helping to make surfaces non-stick as well as adjusting and setting viscosities independent from temperatures. PTFE Micropowders made by Dyneon GmbH are available in four variants, have excellent non-stick properties and an almost universal chemical resistance. They can be used long-term in a wide temperature range, from
-190 °C to +260 °C. In addition, they have a high level of resistance to the effects of weather, especially UV rays.

Recommendations for the use of 3M Dyneon PTFE Micropowders range, depending on the type used, from coating formulations, through high-temperature fats, waxes and oils to print dyes and anti-friction coatings. In addition, 3M Dyneon PTFE Micropowders are used as additives in a wide variety of plastics to decisively improve their coefficient of friction and surface characteristics.

3M Novec Fluorosurfactants

For ten years now, 3M Novec Fluorosurfactants as additives in paints, varnishes and adhesives have been helping to wet difficult surfaces and prevent defects in covering coatings. In addition to its three tried and tested, non-ionogenic products FC-4430, FC-4432 and FC-4434, 3M now also offers an anionic fluorosurfactant (FC-5120). It is based on ammonium salt, so it is particularly easily soluble in water and thus mainly suitable for aqueous formulations. This spring, a cationic product variant which was specially developed for use in the acid pH range is also to be launched.

Based on C4 technology

All 3M fluorosurfactants are based on C4 technology and are classified as more compatible with regard to the health and safety and environmental protection legislation. 3M was one of eight companies to sign up to the voluntary undertaking to produce short-chain carbon compounds (U.S. EPA 2010/15 PFOA Stewardship Program) and was the first manufacturer to introduce short-chain products back in 2002.

Novec fluorosurfactants can help to reduce surface tension to around 20 mN/m. In comparison, hydrocarbon surfactants, which have to be used in larger quantities, only achieve values of up to 30 mN/m and silicone-based surfactants reach 25 mN/m.
