Overview
Mould release oil aerosol spray is an industrial auxiliary product formulated to prevent adhesion between mould surfaces and finished parts during manufacturing processes. It is widely used in plastic injection, rubber moulding, polyurethane foaming, composite production, concrete casting, and metal forming.
The chemical system is designed to create a thin, lubricating, non-stick film while ensuring easy aerosol application and surface compatibility.
Main Chemical Groups Used
Release Oils (Primary Active Phase)
These oils form the non-stick barrier on the mould surface.
-
Mineral oils
-
Synthetic lubricating oils
-
Vegetable oil derivatives
-
Ester-based release oils
Selection depends on temperature resistance, mould material, and surface finish requirements.
Lubricity and Slip Enhancers
Improve release efficiency and surface smoothness.
-
Fatty acid derivatives
-
Fatty esters
-
Long-chain hydrocarbons
They reduce friction and prevent product sticking.
Solvent System
Solvents control viscosity, sprayability, and film spreading.
-
Aliphatic hydrocarbon solvents
-
Isoparaffinic solvents
-
Low-aromatic solvent blends
Solvents evaporate after application, leaving the release film behind.
Corrosion Inhibitors
Protect metal moulds from rust and oxidation.
-
Metal passivators
-
Oil-soluble corrosion inhibitors
Especially important in high-humidity or frequent-use environments.
Anti-Wear and Film Stabilizers
Improve durability of the release layer.
-
Boundary lubrication additives
-
Film-strengthening agents
They extend mould life and reduce reapplication frequency.
Stabilizers
Maintain chemical stability and shelf life.
-
Oxidation inhibitors
-
Compatibility stabilizers
Prevent degradation of oils during storage.
Aerosol Propellant System
Enables uniform spray delivery.
-
Hydrocarbon propellants
-
LPG-based propellant blends
Must be compatible with oil-based formulations.
Optional Functional Additives
Depending on application:
-
Anti-drip agents (for vertical moulds)
-
Low-odor additives
-
Dye markers for coverage control
Surface Compatibility
Properly formulated mould release oil aerosol sprays are suitable for:
-
Steel and aluminum moulds
-
Plastic and rubber moulds
-
Composite and PU mould systems
-
Concrete and construction moulds
Safety and Regulatory Notes
-
Use only approved industrial chemicals
-
Ensure proper ventilation during application
-
Avoid prolonged skin contact
-
Clearly label flammability warnings
-
Follow local aerosol safety regulations
Summary
The chemicals of mould release oil aerosol spray consist of a balanced system of release oils, lubricity enhancers, solvents, corrosion inhibitors, stabilizers, and propellants. When properly selected, these chemicals provide effective demoulding, surface protection, and reliable aerosol performance, making them essential in industrial moulding operations.
