Applicable Base Polymer Properties

On drying, solutions of methyl cellulose give clear, colorless films that are resistant to oils and organic solvents. Methyl cellulose is used for paper coating and sizing to impart grease resistance and in adhesive for leather drying. The leather application takes advantage of the fact that upon heating methyl cellulose thickens reversibly.

Processing

Resulting Properties

Cellulose adhesives adhere well, forming a tough bond to a variety of mainly porous materials. They are oil resistant and age fairly well, but discolor in sunlight. Having a high viscosity and good tack, they develop strength rapidly with tough films being formed even with some residual solvent present. The adhesive formulation provided above can be used for manufacturing and repairing leather shoes.
