Product Description

ELECTRIC SPRAY VARNISH provides a tough impervious insulating seal ideal for components subjected to difficult environments and high humidity. It is particularly suitable for improving leakage characteristics of terminal assemblies. Also seals off electrical leakage paths and has excellent resistance to transformer oils and moisture. Excellent noise reduction characteristics too. Dries rapidly to form a red coloured film. Conforms to international standards see below.

BENEFITS

• Insulates all types of electrical systems against high humidity and other difficult environments
• When applied to cores before rewinding - significantly shortens rewinding time
• Tough and impervious
• Dries rapidly to form a thin film of red varnish
• Highly effective in sealing potential leakage paths - including high voltage transformers and switch-gear
• Seals cut edges of laminated products under humid conditions
• Excellent noise reduction characteristics
• Resists transformer oils and moisture
• When cured - conforms to BS 5629 type 1.1 (IEC 85)
• Suitable for use in thermal Class B and F insulating systems
• Low hazard fungicide included in the products formulation which gives it an 0 rating (no growth) fungal resistance when tested to BS 3900 PTG6
• Ideal for tropicalisation and for use on equipment working in warm -humid climates
• Will not damage delicate electrical parts

APPLICATION METHOD

Apply to a clean - degreased surface. Shake can vigorously for about one minute after ball is heard. Spray object at about 30 cm (12 inches) at a minimum room temperature of 10C. Do not apply excess amounts. When finished spraying - invert can and spray for a second to remove excess product from the spray head.

Curing Product can alternatively be heat cured at 80C for two to three hours the equivalent of 24 to 48 hours at ambient. This is particularly recommended for tightly wound - heavily taped or large components to reduce the risk of solvent entrapment.

STORAGE

The product may be stored at normal ambient temperatures and has a shelf life of not less than 24 months with correct storage. Aerosols should always be stored below 50OC - away from direct heat and naked flame.
