Solfluid EL310 and EL410 – Sinker EDM Dielectric Fluids
Odorless and colorless dielectric fluids for sinker EDM operations
SCUMED offers two highly refined dielectric fluids for sinker EDM operations: Solfluid EL310 and Solfluid EL410. Both ensure fire safety, constant workpiece transparency, excellent filterability, and rapid metallic debris separation. The EL410 model stands out for its FDA purity certification and higher flash point, making it ideal for applications requiring maximum safety and extended electrode life.

FAQ – Solfluid EL310 and EL410 EDM Fluids
Q: What is the main difference between EL310 and EL410?
A: Solfluid EL310 is the standard high-refinement fluid with a 73°C flash point, ideal for most finishing applications. Solfluid EL410 is high-purity and non-toxic, with a flash point above 100°C and FDA 178.3620(b) certification, designed for operations requiring greater safety and extended electrode life.

Q: Are both fluids suitable for sinker EDM operations?
A: Yes, both EL310 and EL410 are specifically formulated for sinker EDM (bath EDM) operations, ensuring constant transparency, excellent filterability, and rapid separation of metallic residues.

Q: How should Solfluid products be stored?
A: EL310 should be stored indoors, protected from moisture, heat, and direct sunlight. EL410 can also be stored outdoors with drums in a horizontal position, but must be protected from frost, sunlight, heat sources, and open flames.

Q: Is Solfluid EL410 FDA certified?
A: Yes, Solfluid EL410 passes the FDA 178.3620(b) purity test, making it suitable for production environments with strict regulatory requirements.
