DOLPHS SYNTHITE AC-43 25 l clear electrical insulating varnish class H

DOLPHS SYNTHITE AC-43 25 l clear electrical insulating varnish for PCB and windings

DOLPHS SYNTHITE AC-43 25 l is a clear air-drying electrical insulating varnish based on modified polyester. The product forms a hard, flexible and clean protective coating on electrical and electronic components. The 25 l version is intended mainly for higher production consumption, serial impregnation and processes where varnish is used regularly.

AC-43 is suitable where a clear electrical insulating coating is required without applying a strongly coloured film. The varnish may be applied by dipping, brushing or spraying, which makes it suitable for production processes as well as workshop and service work on a larger number of components.

Application of DOLPHS SYNTHITE AC-43 25 l

DOLPHS SYNTHITE AC-43 is used as a clear protective and electrical insulating coating for components operating in electrical and electronic systems. It helps protect surfaces against moisture, chemical agents and corrosion while maintaining good adhesion and penetration.

Typical applications include printed circuit boards, stators, coils, form wound coils, transformers, resistors, capacitors and other components requiring a clear protective coating with electrical insulating properties.

What makes DOLPHS SYNTHITE AC-43 25 l different

The key advantage of this product is the combination of fast drying, a clear coating and high-temperature resistance. The varnish forms a film with very good hardness and flexibility, which is important for components exposed to thermal load, vibration, moisture or selected chemical agents.

The 25 l package is practical where electrical insulating varnish is used repeatedly: in production, winding repair, impregnation of electrical components or processes where smaller packages would be less economical.

When to choose DOLPHS SYNTHITE AC-43 25 l

This version is a good choice when a larger quantity of clear electrical insulating varnish is needed for regular application. The product is suitable where thermal class H, fast drying, good penetration and multiple application methods are important.

Important notes before use

Before application, the surface should be clean, dry and prepared according to process requirements. The product may be applied by dipping, brushing or spraying. For fast conveyor dipping processes, the manufacturer indicates that the varnish may be diluted by 10-15% using DOLPHS T-200 thinner.

FAQ

Is DOLPHS SYNTHITE AC-43 25 l suitable for PCB protection?

Yes. The indicated applications for SYNTHITE AC-43 include printed circuit boards. The product forms a clear protective coating with electrical insulating properties.

When should the 25 l package be chosen instead of 5 l?

The 25 l package is suitable for higher, repeatable consumption, for example in production, serial impregnation, repair of electrical components or processes where the varnish is used regularly.

Is DOLPHS SYNTHITE AC-43 clear?

Yes. AC-43 is a clear varnish, which makes it suitable where the protective coating should not cover components, markings or visual inspection areas.

Can the varnish be applied by brush?

Yes. The manufacturer indicates application by dipping, brushing or spraying. The method should be selected according to the component, process and required coating thickness.

Can the varnish be oven dried?

Yes. The product air dries, but oven drying is also possible. The manufacturer indicates that drying for 20-30 minutes at 150°C provides a film with optimum toughness and bond strength.

DOLPHS SYNTHITE AC-43 25 l is a practical version for production and service applications where a larger quantity of clear class H electrical insulating varnish is required.
