Persia Heat-Resistant Glass Varnish | High-Performance Insulating Varnish for Electric Motors
Persia Heat-Resistant Glass Varnish is a premium electrical insulating varnish made from saturated polyurethane resin (Saturated Polyurethane) combined with high-purity organic and inorganic chemicals. It forms a glossy, uniform coating with exceptional adhesion, providing strong mechanical stabilization of windings while improving thermal and electrical resistance.
With a thermal resistance of 138°C, this varnish is suitable for insulating coils and components exposed to high operating temperatures in light and heavy-duty motors, dynamos, transformers, and wound armatures.
Key Features

Thermal resistance up to 138°C
Fast initial drying in 30 minutes
Full curing in approximately 5 hours at 25°C
Excellent penetration into winding layers
Enhances dielectric strength
Reduces vibration and noise in motors
Protects against moisture, dust, and industrial contaminants
Compatible with AC and DC systems
Applications
Persia Heat-Resistant Glass Varnish is ideal for insulating and stabilizing wound electrical components, including:
Dynamos
Light and heavy-duty electric motors
Transformers
Armatures
Industrial coils
AC/DC wound electrical equipment
Preparation and Thinning
Dilute the varnish with Persia Thinner 1124 in the appropriate ratio.
Mix thoroughly to achieve the desired viscosity.
The dilution ratio may vary depending on the application method (immersion or brush).
Application Method
Pour a sufficient amount of varnish over the winding.
Fully immerse the component in the varnish container.
Apply the varnish to sensitive areas using a brush.
Allow to dry at ambient temperature (25°C).
For faster curing, controlled industrial drying ovens can be used.
Advantages
Prevents short circuits and electrical discharge
Improves mechanical strength of windings
Extends equipment life under high temperatures
Reduces maintenance and operational downtime
Enhances motor efficiency and safety
