Dosage
Prior dilution is recommended if NOVASIL 333 is to be added in padding baths where other finishing products already exist.
The dosage varies according to the type of finish to be obtained, however keeping between 30 and 300 g / l it is recommended
to dry at temperatures between 130 ° and 150 ° C with times ranging between 40 and 90 seconds (for dispersed dyes do not
exceed 140 ° C). Further calendering treatments will ennoble the finishing with NOVASIL 333.
Properties
NOVASIL 333 gives the treated fabric the following characteristics:
– Elastic and full hand.
– Good wearability.
It also offers the following benefits:
– Possibility of use in high dosages.
– Does not require catalysts.
– It is odor free.
– It is solid to dry and wet cleaning.
– It is solid in UV light and sunlight.
With the addition of CATALYST 831 (10% by weight of resin) the fastness to washing is improved.
Applications
NOVASIL 333 is applied by heat-cross-linking. It is a product that gives a “resin” finish with a soft and full characteristic on all
types of fabrics. It is particularly recommended on cellulosic fabrics that need a snappy effect and a swollen hand. Using high
dosages of NOVASIL 333 applied by padding it is possible to obtain a thickener fabric with a coating-like effect.
