Demoulding

High-performance semi-permanent release agents

SURFACTIS Technologies develops semi-permanent release agents that interact durably with the surface of moulds.

By bonding to the tooling, our coatings create a stable non-stick layer that facilitates demoulding cycle after cycle, with a much lower application frequency than a conventional release agent.

Your benefits

Our semi-permanent release agents enable you to :

Secure your demoulding processes
Reduce scrap and rework
Increase line productivity
Improve the quality perceived by your customers
Better control your costs and regulatory compliance

How does it work ?

Our products come in the form of a liquid solution that is easy to apply:

by spray
by dipping
or by brush, depending on your process constraints

They bond to the mould in seconds, permanently reducing its surface energy and significantly reducing the adhesion forces between the part and the mould.

The result : easier, faster and more repeatable demoulding.

As semi-permanent agents, they :

form a film anchored to the mould, effective over several cycles
do not need to be reapplied after each demoulding
can be removed during maintenance operations (specific cleaning).

They are operational up to 150°C, preferably on metal or ceramic surfaces, for numerous applications in plastics, composites and polyurethanes.

Strong interaction with the mould provides:

better resistance to cycling than silicone oil or sacrificial release agents
little or no transfer to the part, facilitating painting, bonding or subsequent treatments.

Positioning in relation to conventional release agents

Compared to silicone oils, waxes and agents that require frequent reapplication, our solutions are genuine semi-permanent release agents :

More durable on the mould : fewer re-applications, fewer line stoppages, less operator variability.
Less transfer onto the part : better compatibility with finishing operations (painting, gluing, controlled adhesion).
Cleaner and more stable process : uniform film, less overconsumption, reproducible demoulding from one mould to another.
Protection of tools : less aggressive cleaning, fewer scratches, extended mould life.
Regulatory compliance : reduction in consumption, emissions and waste for better control of HSE issues.

Main areas of application

Our semi-permanent release agents are particularly suitable for :

Plastics – thermoplastics (< 150°C) Injection, blow moulding/injection blow moulding, thermoforming for technical or aesthetic parts (automotive, electronics, cosmetics, pharmaceuticals, etc.).
Composites – polyester/epoxy Lamination and open moulding (boating, bodywork, design), RTM light, infusion and small technical parts (glass/epoxy, carbon/epoxy, etc.).
Low-temperature moulded polyurethanes Foams or compacts (soles, design parts, comfort elements). Our treatments offer a controlled demoulding environment, subject to compatibility tests with your formulations.

Technical support

The best way to evaluate our semi-permanent release agents is to test them on your own moulds.

We can help you :

choose the right product for your substrates and materials
define the application conditions (surface preparation, number of coats, drying time)
monitor concrete indicators: scrap rate, cleaning frequency, number of cycles between two applications, cycle time.
