International. Chitosan or chitosan has gained significant attention in recent decades as a potent natural adhesive. Its low concentrations (<10% w/v) offer competitive strength as synthetic adhesives that would reduce the economic constraints of adhesive production.
A study published in the Biochemical Engineering Journal, indicates that there is a growing commercial interest in chitosan as it possesses biodegradability, biocompatibility, non-toxicity and anti-microbial properties that are of great interest to industry and consumers. In addition, it has reactive amino side groups, which offer possibilities for chemical modification, increase ionic interactions and graft reactions, etc. The degree of deacetylation (DD) and molecular weight (Mw) is important in the binding mechanism.
Most synthetic adhesives are made up of petrochemicals that leave toxic residues such as formaldehyde and volatile organic compounds (VOCs). Therefore, the development of environmental green adhesives, cost-effective and healthy, based on renewable resources is the main interest of adhesive industries these days.
Rising oil prices are another driving force in research for the development of bioadhesives as a substitute for synthetic adhesives. This review focuses on the current evolution of chitosan adhesives for general adhesion and structural applications in recent decades, as well as their current potential in the market worldwide.
Buen día me interesa una membrana o recubrimiento plástico que contenga Quitosano, tendrán algún producto??
