Single-component water-based insulating dip coating with excellent dielectric performance and water resistance for transformers, motors, generators and circuit boards. Uniform film formation with minimal application loss. Bake cure at 120–150°C, 25µm DFT.
Overview
Waterborne insulating dip coating for electrical coils and components requiring dielectric strength and temperature resistance.
Film emphasizes insulation, water resistance, and abrasion resistance for coils and windings operating at elevated temperatures.
Composition
Specially modified resin with waterborne curing agent, pigments/fillers, special additives, and deionized water; waterborne dip-coating system using water as thinner.
Typical uses
Impregnation of electrical coils operating short-term at 250–300℃ and in continuous service at 180–200℃.
Suitable for transformers, motors, starters, generators, printed circuit boards, coils, resistors, armatures, capacitors, spindles, rotors, magnet wires, and other insulated components.
Technical data (typical)
Appearance: transparent or semi-transparent liquid.
Density: 0.85–1.05 kg/L.
Theoretical consumption: 0.08–0.1 kg/m² at 25 µm DFT (loss not included).
Drying schedule: 120–150℃ for 40–60 min.
Dielectric strength: ≥70 MV/m at 25±1℃ (dry); ≥50 MV/m at 25±1℃, RH 95±3% (humid).
Application data (25°C)
Application method: dip coating.
Thinner: clean water, added according to viscosity requirements.
Post-dip handling: components to drip in a constant-temperature, clean environment until no visible drips before oven curing.
Surface preparation
Surfaces of components must be clean and free from contaminants; dipping gaps and spacing between workpieces to be controlled for proper impregnation and drainage.
System compatibility / packing / storage
System compatibility: insulating impregnation layer within electrical insulation systems for motors, transformers, and coils.
Construction conditions: ambient 5–35℃; maintain appropriate spacing during dipping to avoid contact and pooling.
Storage: cool, ventilated area at 5–35℃; avoid sunlight, severe cold, and rain.
Shelf life: 6 months.
