Create fluorescent whiteness of flour solution

Brightener Tinopal UP Liquid is a suitable use for the meal solution slightly acidic or neutral pH. Brightener creates special advantages when using soft water in manufacturing paper and contact time between brightener and short meal solution. This particular brightener bring high efficiency when used with powders containing different ratios between mechanical pulp and recycled fibers recovered

Brightener used for surface sizing

Brightener Tinopal Up is not recommended for use in molding optical parts

Applications for surface coating

Up brightener Tinopal best used with the coating mixture as the mixture of casein / latex or mixed protein / latex as well as mixtures of copper adhesion.

Brightener used for the wet

Up brightener Tinopal great affinity and used very effectively with non-adhesive papers and when used with very soft water (<7 ° G. h. Or <70 ppm CaO). Do not be influenced by the nature cations, increased white matter is best used for sizing paper, with synthetic additives.

Brightener particularly well suited and promotion with a brightness of fluorescent paper sizing at pH 4.8 was - 6.5 and has many good advantages when used with increased white matter volume types tetrasulpho with smaller capacity 0.4 %.

Accelerators increase Tinopal UP Liquid may be granted an interruption in meal or report them to the mixing tank. Need grade substances into acupuncture points before the alum and never supplied with alum and other additives.

With high affinity, improvers this increase can be lit constantly, even at point magnet powder dilute concentrations.

The average dose of 0.05 to 1.5% at pH 5 and 0.6% greater than 0:05 to less than 4.8 in pH

Applications for the squeeze

As mentioned above, brightener Tinopal UP not really effective for the presses. Consumption of brightener is applied in powder is smaller presses 4g / l solution and pressed white rose at average levels. We recommend using brightener Tinopal ABP type or kind Tinopal SPP for the squeeze

Applications for surface coating

Great results can be achieved when using this substance in the mixture increases translate floors coated with casein binders or protein.

The best results achieved with coating services using synthetic adhesives and latex.

Brightener should not be used with coated translated using starch adhesives

With these services using adhesive coated starches, we recommend that customers use brightener Tinopal ABP categories, Tinopal SPP or Tinopal SK Slurry.

Quantification Median: 0.1 to 2.0 parts Tinopal UP Liquid (part pigment) to 0.6 for paper 0:05 baova SC- paper (part by weight of dry cellulose)

Preservation:

Tinopal UP has good stability when

stored at cool temperatures. Preserving long time at temperatures below -10 ° C can make the icing. Products icing can be restores functionality without affecting efficiency by letting the product at room temperature or heated to temperatures no higher than 50 ° C.

Containers preserved if fitted paddle better.
