Microcapsule Blue

Attachments:

Microcapsule Blue is an aqueous emulsion of microcapsule for the production of carbonless copying papers. It contains no binder or spacer. The core material of each capsule consists of a mixture of blue color formers dissolved in a liquid carrier. The average capsule diameter is about 3-6.0 micron.

Temperatures below freezing point have no adverse effect on the integrity of capsules. The emulsion that has been frozen may be used again upon thawing.

Because microcapsule possesses highly impermeable shell, it is possible to manufacture self-contained copy paper in one pass by mixing microcapsule with CF coating slurry.

Typical Information:

  • Form: Aqueous emulsion
  • Solid contents: 50.0%±1%
  • PH value: 7.50-9.50
  • Viscosity: 30-400 cps(at 25℃,Brookfield viscometer 60rpm)
  • Colour: Blue White

Features:

  • Very good mechanical and storage stability.
  • Mononuclear capsules.
  • High copying intensity.
  • High solid content.

Microcapsule blue may be applied in the concentrated or dilute form, depending upon the coating process.

The amounts of binder and spacer added can be adjusted to produce the desired properties of the finished paper. For example, higher amounts of these additives will result in a greater level of smudge resistance. At a slightly reduced copying intensity. On the other hand, lower amounts of binder and spacer will give better copying intensity with less concern on the smudge resistance.

Package:

200 kg per drum.

Application Method:

1. Adding water

2. Stiring when adding spacer(stirring time: 25-30 mins), untill all is dissolved

3. Adding microcapsule and stirring about 15 mins

4. Add modified starch liquid, and styrene butadiene, stirring about 20 mins

 

Microcapsule green or purple can be customized for you.
