Dextrins

White Dextrins & Yellow Dextrins are polysaccharides formed by heating dry or acid-modified starches in a process called pyrolysis. They can be used at higher solids levels than native or modified starches, creating stronger bonds, more tack and faster-drying properties than pastes made from unmodified starch. Dextrin pastes provide excellent machinability and also can be used in adhesives and coatings that come into contact with food products, child-safe school pastes, remoistenable wallpaper, bag/envelope seams and paper and textile sizing.

 

White dextrins and Yellow dextrins are soluble in water.

Applications 

Everest quality starch adhesives with value added technical support find their way all around the globe. Dextrins are used in wallpaper, paper sack, tube winding, envelope, remoistable PVAc and gummed tape adhesive.

  • Carbon paper manufacturing, abrasive and in dry distemper.
  • Machine labeling of tins /cartoon packages envelop corrugated boxes.
  • Also used by crackers manufacture due to adhesives properties .
  • In book binding cartoon sealing cigarettes pasting match head and matchbox making.

Yellow Dextrin is also widely used in the manufacturing of:

  • Wallpaper adhesive
    The high viscous Dextrin starch wallpaper adhesives dissolve easy, lumpfree, are pH neutral and in line with the latest legislation regarding preservatives. These Modified starches are in use as main raw material for wallpaper paste.
  • Paper sack
    The production speed of paper sack machines increases all the time, so demand for high quality adhesives also grows. Everdex series paper sack adhesive range is recognized by the paper sack adhesive manufacturer for it’s consistent quality.
  • Tube winding
    Everdex dextrins for paper core adhesives ensure good wet tack, fast drying and reliable dimension stability to paper mill cores manufacturers. Dextrin based paper cores adhesives are used to make paper Cones (Paper Tubes ), composite cans, protective packaging and fibre drums and other paper products.
  • Remoistable envelop adhesive
    Envelope adhesive formulations needs a yellow dextrin that brings high wet tack, visco-stability, application control, light colour and excellent dry bond with fibre tear. We offer the stable yellow dextrins product range of low to medium viscous yellow dextrin ingredients so you can fine tune the price performance to your customers.
  • Remoistable PVAc
    For the production of a good remoisable PVAc emulsion, a protective colloid with good stability, minimal impurities, high quality and reproducable products are needed. Everdex dextrins deliver these needed qualities.
  • Aluminium foil
    When producing laminated paper aluminium foil for inner cigarette wraps, meeting the high quality demands of the cigarette industry, running trouble free production and having a fast laminating adhesive are important characteristics. Everdex dextrins delivers with minimal consumption, no synthetic smell and a flexible dry bond the high performance fast adhesive you are looking for.
  • Gummed tape
    For manufacturing water activated, remoistable gummed paper tape high initial wet tack, fast fibre tear and good flow are important characteristics for the ideal gummed tape adhesive.One of Everdex series modified starch product range was developed to meet these demands.

  • Foundries
    Yellow dextrin gives an excellent binding agent for sand cores in foundry operations. It gives high green bond strength necessary for the mould to remain intact during handling.
  • Chemical & Dyes Industries
    High soluble white dextrin is used in dye stuff industries as diluents to standardized the dyes with respect to the range of color. Dextrin washes out quickly and easily and do not react with chemicals used in the process
  • Textile Industries
    As dextrin do not easily react with chemicals, they are specifically suitable for application in the textile field. In Textile printing, they are used as thickener. Free of grit and other impurities, which usually accompany lower grade of starch, they ensure that the copper rolls (used in printing) do not suffer from abrasion. In sizing, they are used with starch to increase adhesiveness. In finishing, they give desired feel to the fabrics.
  • Color Industries
    Dextrin is largely used in dry distemper. five to ten % of dextrin, mixed with chalk and pigment, acts as carrier and impact good adhesion of the color to the wall.

 

  • Remoistable PVAc
    For the production of a good remoisable PVAc emulsion, a protective colloid with good stability, minimal impurities, high quality and reproducable products are needed. Everdex dextrins deliver these needed qualities.
  • Textile Industries
    In Textiles,Everdex Dextrins are used For finishing (crisp organdy) as well as for sizing.
