FS7360R Water-Based Epoxy Self-Adhesive Silicon Steel Coating
High-performance water-based coating designed for self-adhesive insulation on silicon steel surfaces and core bonding and molding.
What is FS7360R water-based self-adhesive silicon steel coating?
FS7360R is a single-component waterborne epoxy emulsion coating designed for self-adhesive insulation on electrical steel surfaces and for bonding and forming transformer cores. Formulated with specialty waterborne epoxy resin, a dedicated curing agent, additives, and water, it forms a tacky adhesive layer after application and baking, facilitating the lamination, positioning, and post-curing of stacked laminations. The resulting core enhances mechanical strength, reduces eddy current losses and motor operating noise, and prevents interlaminar corrosion.
Water-based eco-friendly formula
Single-component waterborne epoxy emulsion system with low odor and low VOC, compliant with EU RoHS and REACH environmental regulations.
Excellent Insulation Performance
The coating offers high insulation and water resistance, effectively preventing interlaminar short circuits and corrosion in silicon steel sheets.
Good punching performance
The coating offers excellent flexibility without compromising the stamping performance of silicon steel sheets, making it ideal for automated production.

Frequently Asked Questions
Common Technical Q&A for FS7360R Waterborne Epoxy Self-Adhesive Silicon Steel Coating
Q: What are the curing temperature and pressure ranges for FS7360R?
A: FS7360R recommends a curing temperature of 160–250°C and a molding pressure of 1.0–3.0MPa. Specific process parameters should be optimized and validated based on your equipment capabilities and product requirements. We recommend conducting small-batch trials first to determine the optimal combination of temperature, pressure, and time.
Q: Does the coating affect the punchability of silicon steel sheets?
A: The FS7360R formula is designed to meet punching performance requirements. After curing, the adhesive layer remains flexible and does not interfere with silicon steel stamping. In practice, coating thickness and uniformity affect punching quality; we recommend controlling the application amount within the specified range.
Q: Is the FS7360R eco-friendly?
A: Yes, FS7360R is a waterborne epoxy emulsion system with low odor and low VOCs. It contains no inorganic salts or fillers and complies with EU RoHS and REACH requirements. Compared to solvent-based coatings, it is more environmentally friendly and safe.
Q: How do I control coating thickness?
Coating thickness is primarily controlled by application process parameters (e.g., roll gap, coating speed) and solid content. We can provide parameter recommendations tailored to your production line. Post-cure thickness impacts insulation performance and the core stacking factor, requiring optimization based on specific applications.
Q: What performance benefits does the FS7360R offer?
The right coating and curing process meets water resistance, insulation, stamping, lamination bonding, and interlayer protection requirements while enhancing core mechanical strength, reducing eddy current losses, and minimizing operating noise.
Q: Is FS7360R a two-component coating?
A: No. FS7360R is a single-component waterborne epoxy emulsion coating that requires no on-site mixing of A and B components, simplifying the application process.
Q: What are the recommended curing conditions for FS7360R?
A: The process range provided in the available documentation is 160–250°C and 1.0–3.0MPa. Specific curing time, temperature, and pressure must be validated based on the silicon steel grade, lamination thickness, core dimensions, coating thickness, and equipment capabilities. We recommend conducting small-batch pilot trials to determine optimal parameters.
Q: Do you provide technical support and sample testing?
Yes, we offer free sample testing and provide process parameter recommendations and technical support tailored to your specific application needs. Contact our technical team to request samples and detailed technical documentation.
