Cassava-Based Adhesives
The
word adhesive as an adjective or a noun refers to substances which
tend to adhere or stick to other substances. The interaction which
develops
between an adhesive and other dissimilar substance(s) when they have
contact is called adhesion. Thus, adhesives are used to unite or bind
materials and are very useful at home and in industry.

Starch production
Cassava-based adhesives, like the cereal starch adhesives, are of three main types:
1.
Liquid starch adhesives
Liquid starch adhesives are supplied by the manufacturer in liquid forms
usually in plastic or lined metal drums or in jerricans and bottles.
They are used by consumers as supplied or diluted further, depending
on specification, with a suitable solvent (usually water). They have
a limited shelf-life (6 to 18 months) and are not usually considered
for export. The high solvent/water content and the relatively low cost
of these adhesives do not also recommend them for export.
2.
Pre-gel starch adhesives
Pre-gel starch adhesives are produced in dry flakes and milled to specific
adequate particle sizes. They are packed in waterproof, lined, multi-wall
paper bags/sacks. They are very suitable for export.
3.
Dextrin-based adhesives
Dextrin-based adhesives are delivered to consumers either in liquid and
dry forms depending on specification or requirement. The liquid dextrin
adhesives are packed in the same way as the liquid starch adhesives while
the dry dextrin adhesives are packed in the same way as the milled pre-gel
adhesives. Dry dextrin adhesives are very suitable for export, especially
to Europe and America where they are used in very large quantities.
