Life is a string
of complex molecules: polymers. Nature's most abundant
protein polymer is collagen, from the Greek meaning
"glue producing". Natural adhesives derived
from animal protein include glues made from collagen.
These natural protein colloids are used as an additive
in adhesives and binders. Natural protein adhesives
(glues) and binders have a variety of unique features
and uses.
In its natural biologically
active status, Collagen (natural protein polymer) is
water insoluble, functioning as a strong and flexible
binder for skin and bone. The collagen molecule exists
as a coiled triple-helix, held in place by chemical
bonding between the individual protein chains. When
subjected to extremes of temperature or acid or alkaline
conditions, the helix "denatures", separating
into three straight-chain polypeptides. The polypeptide
can then be removed from the native skin and bone, hydrolyzed
to the desired molecular weight, and dried or compounded
for the intended application.
Natural adhesives
derived from animal protein include glues made from
collagen, a constituent of the connective tissue and
bones of mammal and fish. These natural protein colloids
are used as an additive in adhesives and binders. Natural
protein adhesives (glues) and binders have a variety
of unique features and uses such as adhesive formulation
and caulks, animal feed binder and supplements, conventional
adhesive uses (tape, book binding, laminating), natural
adhesives for paper industry (core winding, sizing,
gaskets), textiles, etc. (Markets
& Applications)
Colloidal Collagen
Protein has a strong specific adhesion for a variety
of substrates. Applied from water solution, the colloids
gel at room temperature forming quick temporary bonds.
Final bonds are formed on drying.
Dilute solutions
in water act as dispersants or flocculants. This behavior
suggests that high molecular weight collagen functions
as a “bio-polymer”, with performance characteristics
similar to water soluble synthetics.
