Making the Switch to a Water Based Release

Making the switch to a water based release doesn’t have to be a scary or overwhelming task. These mold releases have some benefits that might fit your company’s needs. If you are considering making the switch, we have pulled together some quick, thought provoking tips for plant managers and mold operators.

The benefits
One of the biggest benefits to making the switch to water based release is the ability to reduce overall Volatile Organic Compounds or VOC’s in your manufacturing facility. This newer release technology is also less expensive to ship, less costly to store and non-flammable. While those benefits are great, making the switch to a water based formula will typically require some process changes.

Stoner Molding Solutions Water-based ReleasesWhat you need to know
To transition from an ambient cure solvent-based system to a semi-permanent water-based mold release, you will more than likely have to add steps to your existing process. Water-based releases require either time, or heat to cure and achieve optimum performance. Adding heat to a mold could mean an internally heated mold or applying heat externally with an oven or autoclave.

New molds or new ovens may not be economically viable option for smaller molders, but the benefits of a water-based release can still be achieved with time. Adding time can be as simple as setting your mold to the side while the water carrier evaporates naturally, or adding a fan to increase airflow and decrease down-time. The key is allowing the release to properly cure. A properly cured mold will often mean that you can achieve multiple releases without re-application. 

If you are replacing a sacrificial solvent based release, you can probably switch to a water based release without needing time or heat.

More good news
TraSys® products provide great release options for most applications, most notably in the rubber and rotational molding markets. The various grades available are ideal for releasing parts,  keeping parting lines clean, removable pins and inserts, or difficult molds in general. There are even high-heat options available for molds reaching above 600-degrees Fahrenheit.

New technologies and new applications are being discovered daily. By combining the talents of Stoners Research and Development team with our state of the art facilities, our experts  would love to learn more about your specific needs and help you identify and develop the best formula for your needs, or possibly manufacture the next generation of mold release products.
