KT/KTL Series

The KT/KTL series are PTFE (Polytetrafluoroethylene) Micropowders which provide low-friction and wear-resistance.

When added to rubber, plastic, or metallic paint, the KT/KTL series facilitates the development of coating materials with a low friction factor and high wear resistance. The series can be used in place of silicon oil, molybdenum di sulfide or carbon graphite (which have been conventionally used to improve low-friction characteristics) or used together with these additives to add outstanding performance to the coatings. Further, the KT/KTL series is effective in preventing scratches.

The KT/KTL series is not limited to thermosetting paints, and can also be added to other various paints (PCM, UV paint, electro deposition paint, water paint, powdered paint, etc.).

The KT/KTL series can be used widely, with a range of coating thickness (5 - 100μm), and clear coatings (glossy or mat). The KT/KTL series does not require grinding by a mill, and a uniform dispersion condition can be obtained by simply stirring with a dissolver.
