Dextrins (White And Yellow) British Gum

Starch and Dextrin Based Adhesives

Dextrins are fascinating starches and like many other discoveries in chemistry they were discovered largely by accident after a fire in a starch factory thermally modified some native starch.

An extremely large and well- known class of adhesives is based on starch and dextrin. These play a very large part in industrial production, especially the packaging industry. Starch and dextrin are principally used for bonding paper products. Most corrugated boxboard for making cartons is bonded with starch based adhesives, and other porous substrates can be easily joined with these versatile adhesives.

About Dextrin

Dextrin adhesives are manufactured by dry-roasting starch in the presence of an acid catalyst. Through treatments with heat and acid, the starch molecules are hydrolyzed into small fragments, and then repolymerized into highly branched, readily soluble polymer molecules of moderate size. corn starch or Tapioca Starch are commonly used because of its low cost and ready availability.

Unlike starch, dextrins are soluble in water. The severity of the heat and acid treatment determines the degree of solubility, which is the basis for classifying dextrins. Finished dextrins are very fine powder varying in colour from pure white to brown.

There are three main types of dextrin adhesives:

1. White Dextrins.

2. Canary or Yellow Dextrins.

3. British Gums.

The differences are determined by the roasting time and the temperature and amount of catalyst used. The below Table describes the properties of these dextrin adhesives.

Property	White Dextrin	Yellow Dextrin	British Gum
Catalyst Concentration	High	Moderate	Small
Solubility	1-95% in water*	Very soluble in water	1-95% in water*
Viscosity Stability	Prone to retrogradation	Good stability	Good stability, higher viscosity than Yellow
Color	White - Buff	Yellow - Tan	Yellow - Brown

The British gums are dextrins with the highest molecular weight and they are the strongest adhesives among the dextrins, but maximum usable solids content is only approximately 25%. Yellow dextrins are the lowest in molecular weight. Materials of this type are available that give a viscosity of only 1700 cps at 60% concentration. The white dextrins have the lowest color of the three. Their molecular weight is intermediate between those of the other two.

Specifications:

Description	White Dextrin	Yellow Dextrin
Appearance	White or Cream White	Yellow Powder
Moisture %	10 to 12	10 to 12
Ash %	0.3 to 0.4	0.5 to 0.6
Solubles	50 to 60	90
pH	2.5 to 3.0	2.5 to 3.0
Acidity for 5 gms using NaOH	1.00 ml.	3 to 4 ml.
Mesh size-pass through 100 Mesh %	99.80	85.00
Insolubles	2 to 3	2f

The range of solubilities of dextrin adhesives are advantageous in that there can be formulated a range of solutions of very different viscosities leading to a variety of gel strengths. These formulations can then be further modified as described in the next section. Generally the same additives and processes used for starch adhesives are used for formulating dextrin adhesives.

Dextrins are often preferred to starch, as they need less or no cooking and much less water to form the paste. This means that drying time is reduced and there is little likelihood of mold infection in warmer climates. As adhesives, dextrins are used in many of the same applications as starch adhesives. Dextrins are also used as a core binding material in the manufacture of foundry cores. Here the main function is to give good green strength and to prevent deformation of the core before being fired in the oven.
