LD Davis is one of the world’s oldest and largest manufacturers and compounders of gelatin glue. Our gelatin glue formulas are 100% non-toxic, recyclable and biodegradable, making them exceptionally environmentally friendly.
What are the ingredents of gelatin glue?
Gelatin glue and jelly glue are the modern terms for protein-based adhesives. In the 1970s, LD Davis started using recycled pharmaceutical and nutritional gelatin from soft and hard capsules to create our adhesive. Additional ingredients include water, Epsom salts, corn sugar, and glycerin.
Gelatin is derived from its parent protein, collagen. It is a hydrophilic colloid in an aqueous solution, nearly tasteless and odorless, vitreous and brittle, and typically faint yellow. Our jelly adhesives contain two types of protein, chondrin, which provides glue strength for bonding potential, and gluten, which offers gelling strength for tackiness or hardness.
How is gelatin glue made?
The manufacturing process begins with obtaining the raw materials required and screening them for quality. After sorting, the materials are poured into a large mixing kettle, heated, and mixed. Once ready, the jelly glue mixture is poured into large trays to dry or gel overnight. The gelled glue cakes are removed from the trays.
Our glue is graded according to its strength or bloom, with a higher bloom indicating a higher grade. Quality control samples are taken of each glue batch and stored in our lab for future testing as required. All formulas are inspected for quality as part of our 12-point quality control system for all incoming raw materials and outgoing finished products. During this quality control, we test for color, viscosity, and odor before use.
