METALFLOW low pressure and gravity lubricants are the result of decades of experience in the field of design, development, and manufacturing of release agents for the metal industry.
The CASTFLOW GR range is comprised of water-soluble release agents formulated to achieve an easy application with spray guns and an excellent and long-lasting film formation in a wide range of temperatures.
Technological solutions that help our clients with their waste management and allow them to comply with the most demanding environmental standards.
Gravity and low-pressure release agents
- Suitable for all types of water and easy to disperse.
- Volatile organic compound-free (VOC), preventing the generation of fogs and odors.
- Homogenous coverage of the entirety of the mold to facilitate demolding and thermal isolation.
- Custom refractory capacity according to the requirements of the molds and parts.
- Excellent surface finishes based on needs.
- Preventing grip and crack problems and cavities because of a lack of isolation.
