The toxicity of the solvents necessary to dissolve PMM resins restrict their wider use by conservators. A typical formulation for a ‘plexiglass’ glue is as follows: Grind, cut or drill a sheet of Lucite to get a cup of shavings. During drying, there is some shrinkage of PVA that exerts contractual forces on the treated object. They claim that any other solvent would only set the glue more. All the others I have tried are good for one application and throw it away. I’ve used it on two different applications of materials that were difficult to get a secure bond and this epoxy was the answer.
When force is applied to plastic, it travels along the polymer chains causing molecules to strain to remain in contact. Twist the glue cap clockwise until it locks, then unscrew in an anti-clockwise direction to open. Step by Step Ensure surfaces to be joined are clean, completely dry and close fitting.
Cellulose nitrate is still used, especially as an adhesive. It has many of the same characteristics of PVA, but it is not internally plasticized as are most PVAs. Therefore, cellulose nitrate has a much greater tendency than PVA to become brittle, crack, and peel off. Storage Should be stored in a dry place at room temperature in the original syringe. Also, remember that it does not take much of this product to produce an extremely strong bond. Also will need some putty type to plug rod holes with same tolerances.
