Motivation
During our research we have used a wide array of molding materials, however none of them was close to matching our specifications. Those materials were:
- Unable to produce desired molding intricacy;
- Had poor adhesion properties - quick delamination;
- Were non-replenishable;
- Classified as dangerous - creating shipping difficulties;
- Expensive.
Result
GlucoEucaLac (GEL) 1.0 – a composition of Glucose (saccarides), Eucalyptus[1] (solvent) and Shellac (polyester type of resin). GEL is a renewable thermoplastic resin (RTR) which can be annealed and molded into a dimensionally stable structure, which demonstrates both microbial resistance and biodegradability. GlucoEucoLac (GEL) 1.0, a biologically derived compound with the following properties:
- Extremely high molding intricacy;
- Excellent adhesion;
- Demonstrates microbial resistance properties;
- Derived from plants and bug secretion creating sustainable industries; recyclable ingredients;
- Glucose and Eucalyptus are commonly available goods in Australian supermarkets, while shellac flakes are easily shippable;
- Relatively inexpensive.
GEL 1.0 properties vary in composition balance and annealing parameters.

GlucoEucaLac (GEL - 1.0) Renewability
- Glucose Syrup is widely used in confectionery like hard candy, caramels, jellies and marshmallows. Glucose syrup is a purified concentrated aqueous solution of saccharides (biopolymer) obtained from green plants (energy storage).
- Eucalyptus Oil is photosynthesized (produced by tree leafs) and distilled, creating a liquid which can be used as an industrial grade solvent. Care should be exercised in with working with any solvent and appropriate safety equipment should be used.
- Shellac is a processed Lacca bug secretion. Shellac is a resin consisting of inter- and intra-ester of polyhydroxy carboxylic acids.
In addition to being used as a molding agent in the construction of mirrors, GEL has scope for a wide range of industrial applications (not limited to): Thermoplastic injection molding, 3D printing, pressure molding, adhering, bonding, filling and repairing.
