Appearance:amber clear viscous liquid
Structure:a compound of diphenylethylene triazine type

Resistance to acid and alkali:suitable for PH2-12
Solubility:soluble in water in any ratio.
Applications:
This product is especially suitable for whitening and brightening paper pulp,knitted goods and cotton fabrics.The whitening effect of VBL will decrease remarkably when the PH value is lower than 6,while NT-3,since more water-soluble groups have been introduced into its structure,does not only have a very good water solubility,but also has a much higher resistance to acid,and thus has a very good whitening effect on cellulose fiber even if the PH value is only 3-4.
Directions for use and dosage:
Since NT-3 is a liquid,not so hard to dissolve as VBL and will not cause dust pollution,it is only necessary to weigh out it according to the whitenes required and dilute it in water in any ratio.The dosage recommended is as follow:1)For whitening paper pulp:3-10‰ on weight of dry paper pulp.2)For whitening knitted goods:
4-8g/l when using paddyeing process,and if 2-4g anhydrous sodium sulfate is added in the padding bath,the whiteness of fabric will be greatly increased.0.4-1.2% O.W.F..when using dipdyeing process.
