Appro Glass Cutting Oils
Description:
Glass cutting oil is a specialized lubricant formulated to assist in the scoring and breaking of glass. It helps improve the cut quality, prolong tool life, reduce drag, and prevent microfractures and chipping. Below are the general specifications and properties you can expect in a high-quality glass cutting oil:
1. Physical & Chemical Properties
| Property | Specification / Range |
|---|---|
| Appearance | Clear to pale yellow liquid |
| Viscosity @ 40°C (cSt) | 5 – 20 cSt (low viscosity preferred) |
| Specific Gravity @ 15.6°C | 0.80 – 0.90 |
| Flash Point (COC) | > 120°C (preferably higher) |
| Pour Point | Below -15°C |
| Odor | Mild or odorless |
| pH (if water-soluble type) | Neutral (6.5 – 7.5) |
| Solubility | Generally insoluble in water |
| Lubricity | High (reduces cutter wheel wear) |
| Volatility | Low (to avoid excessive evaporation) |
| Residue after evaporation | Minimal or none |
2. Performance Characteristics
- Non-staining: Should not stain or discolor the glass.
- Low evaporation rate: Important for extended usability during continuous operations.
- Corrosion inhibition: Should contain additives to prevent corrosion of tools and machinery.
- Easy cleanability: Should be easily cleaned with water or mild solvents.
- Compatibility: Should not affect glass adhesion processes like lamination or coating.
3. Types of Glass Cutting Oils
- Petroleum-based (Mineral Oil): Common for general use; good lubricity and low cost.
- Synthetic: Higher performance, lower odor, often more environmentally friendly.
4. Additives (if applicable)
- Anti-wear agents
- Corrosion inhibitors
- Friction modifiers
- Anti-oxidants
- Anti-foam agents
