High Temperature Insulation Paint

 

Introduction

 

High temperature insulation paint is a modified epoxy coating that forms a heat-resistant insulating barrier on electrical equipment surfaces.

Note: Main agent color can be customized.

1. Exceptional Thermal Stability
Glass transition temperature (Tg) > 160°C, ensuring coating rigidity at 155°C continuous service, preventing thermal creep.

2.Excellent Dielectric Properties
Volume resistivity ≥1.0×10^12 Ω·cm, high insulation blocks leakage current and reduces core eddy current loss.

3. Superior Corrosion Resistance
Forms a dense physical barrier, offering excellent resistance to humidity, salt spray, and industrial corrosives.

Motor and Transformer Cores
Maintains dielectric integrity at 155°C continuous service, reducing eddy current losses.

Electrical Components in High-Temperature Environments
Resists thermal aging and industrial corrosion for extended service life under harsh conditions.

Metal Structure Protection
Creates a dense barrier against moisture, salt spray, and chemical exposure.

Surface Preparation
Substrate must be clean, dry, oil-free, and rust-free; sandblasting to Sa2.5 is recommended for optimal adhesion.

Mixing
Mix main agent and hardener at a 4:1 mass ratio until homogeneous, avoiding air entrapment.

Application
Apply by brushing, spraying, or dipping to achieve uniform coverage.

Curing
Cure at room temperature for 24 hours, or accelerate with 2 hours at 80°C.

We offer flexible customization to meet diverse application needs:

Color options (standard black, also available in transparent or gray)

Viscosity tailored to different application methods

Adjustable thermal class (130°C to 180°C)

Flame-retardant or low-smoke halogen-free formulations available

FAQ

Q1. Does it require pre-heating before application?
Usually not. This coating can be applied at ambient temperature. If the substrate surface temperature is below the dew point, slight pre-heating is recommended to prevent condensation from affecting adhesion.

Q2.How does it reduce eddy current loss?
With high volume resistivity (≥1.0×10^12 Ω·cm), this coating effectively blocks the leakage current path between transformer core laminations, reducing eddy current generation at the source.

Q3.What are the substrate surface preparation requirements?
The substrate surface must be clean, dry, free of oil and rust. Sandblasting to Sa2.5 grade is recommended to ensure optimal coating adhesion.

Q4.What are the storage conditions?
Store in a cool, dry, ventilated warehouse, avoiding direct sunlight. The recommended storage temperature is between 5°C and 35°C, away from fire and heat sources.
