OPTAVON NW

Sequestering and dispersing agent for pretreatment and dyeing;no demetallising effect on dyestuffs

organic phosphorus compoundChemical composition

Appearance: clear, slightly yellowish liquidIonicity: anionicSolubility / Emulsifiability: dilutable with cold or warm water in all proportionspH-value of 1% solution: approx. 6.5Resistance: applicable within a pH range of 1 to 14;

resistant to organic acids and to oxidising and reducing bleachingagents in usual concentrations

Storage: at least 12 months if properly storedStability to frost: reversible change of state in case of frost

(in case of persistent frost, the product solidifies but is applicableafter thawing and stirring)

Characteristics

multi-purpose use as a sequestering and dispersing agent high iron binding power prevents precipitations of calcium and magnesium salts in alkaline scouring and

bleaching processes, in particular when silicate is used very good soil suspending power applicable in dyebaths as a dispersing and sequestering agent foam-free, applicable in jet machines and short liquor ratios corrosion inhibiting "bluesign approved"

Application properties

OPTAVON NW is used in pretreatment processes and dyeing.

Used for washing out of lubricants, alkaline scouring processes and hydrogen peroxidebleachings, OPTAVON NW prevents precipitations of calcium and magnesium salts and showsa high soil suspending power.

OPTAVON NW

OPTAVON NW is fully effective in the strong alkaline range as well and can be used inmercerising lyes and highly concentrated feeding liquors of continuous pretreatment systems.

In dyeings and subsequent washing operations, OPTAVON NW prevents the formation ofdyestuff agglomerates and supports the cleaning effect. OPTAVON NW has no negativeinfluence on the light fastness of a dyeing.

The calcium binding capacity of OPTAVON NW is about 190 mg CaCO3 /g product, and the ironbinding capacity is 390 mg Fe3+ /g product (both values at pH 11).

For water correction about

0.07 g/l OPTAVON NW

per 1dH (German Hardness) are necessary.

In washing out of lubricants

0.5 - 1.5 g/l OPTAVON NW

should be added depending on the liquor ratio.

In bleaching baths and alkaline scouring processes, the suggested amounts are

1.5 - 3 g/l OPTAVON NW.
