The Fabric Industry has been searching for a coating which offers the same performance as C8 (PFOA) technology, yet without the obvious negative attributes. It became apparent that a technology based on SiO² could prove to offer the solution, and this has indeed proven to be the case.
The new Hybrid coating, which also utilises an environmentally optimised, slightly cationic, C6-carbonfluoropolymer, is PFOA-free, stunningly Hydrophobic and Oleophobic, Self Healing and most importantly Machine Washable.
CCM HFNSF with self-healing characteristics
Our experience of working with SiO² based coatings informed us that this technology offered us the best foundation from which to create a new coating.The main obstacle to overcome was “enhancing the bonding characteristics of the coating”. This obstacle was overcome by creating a hybrid matrix, which, when heat cured would provide a coating which would not only match but supersede the performance characteristics of standard C8 fabric coating technology.
PFOS and PFOA free
F-C Modified silica. The fluorinated component is very strongly bonded to the SiO².
Bonded structure massively reduces degradation of the coating.
Outstanding oleophobicity oil repellency 8, ISO 14419 (depending upon fabric type
Washing stability 25-100 washing cycles
(AATCC) Test Method 135, ECE formulation washing powder, non-phosphate reference
Oil repellency: ISO 14419 / 8-6 (depending on the substrate), self-healing prompted by tumble drying
Water repellency: AATCC 22 / 100, ISO 4920 / 5
Temperature stability: 220°C
Outstanding UV-stability > 3.500 hours
Outstanding washing stability 25 to 100 cycles (self-healing)
Good stability after chemical cleaning
Target Groups for Textiles
Coated with Hybrid Fluorinated Nano Silica Fusion Technology (HFNSF) with self-healing characteristics:
This coating is designed specifically for industrial application. The constituents are supplied in batch specific amounts. eg. clients will receive the constituents suitable for creating 1000L, 2000L, etc..
Simply mix the constituents into water to create the HFNSF coating.
Pre-drying at 100°C is recommended as the fabric must be dry before “curing”.
Curing 1 min. at 170°C-175°C for light/medium fabrics, 90 seconds for heavier fabrics.
Foulard application is recommended.
Stability of mixed coating: 2 days
Shelf life of the components: 1 year
Low Temperature Variant
We offer a variant which is designed for white fabrics which can „yellow“ at higher temperatures. This variant is also suitable for fabrics which will not withstand curing at 170°C-180°C. This low temperature variant should be cured at 150°C. This slightly more expensive variant offers almost identical performance to the standard coating.
