New Clariant Dyestuffs

摘要

Clariant has recently launched a number of new dyestuffs including Foron Black AS-3LF. This new disperse dyestuff for high light-fast applications is the successor to Foron Black AS-LF. A high light-fast and hot light-fast black disperse dyestuff, it is 30% stronger than Foron Black AS-LF and characterised by good build-up. It achieves a neutral shade under different light sources and low colour fading after exposure to light. It is suitable for complying with all common automotive light-fastness standards and characterised by excellent sublimation fastness up to 180℃ at 30 seconds, with very good combinability with UV-absorbers such as Clariant's Fadex. Foron Dark Blue S-WF is being introduced to cover a current colour spectrum matching gap and is intended to be employed as a base element for dark blue and navy shades. It displays a better cotton reserve when compared to Clariant's Foron Navy S-WF and is therefore an excellent choice for PES/cotton blends. Due to its excellent exhaust behaviour and very high sublimation fastness, Foron Dark Blue S-WF is suitable for both exhaust and continuous (SWIFT) applications.
