Kontakt Chemie Clear Acrylic Resin Conformal Coating Spray 200 ml, Dielectric Strength 80kV/mm, Operating Temperature 74309

Kontakt Chemie 74309 is a clear acrylic resin conformal coating supplied in a 200 ml aerosol package designed for effective protection and electrical insulation of electronic components and printed circuit boards (PCBs). It exhibits a dielectric strength of 80kV/mm and functions reliably within a temperature range from -40°C to +60°C, making it suitable for diverse environments.

This coating applies as a low-viscosity liquid spray, creating a transparent finish that does not obscure the visibility of components, helping technicians inspect components post-application. It protects PCBs, transformers, ornaments, furniture, paint surfaces, and paper by forming a moisture-resistant and corrosion-inhibiting barrier.

The product is compatible with metal, paper, and plastic surfaces; however, testing is advised on plastics sensitive to stress cracking. It dries to the touch within approximately 20 minutes at 20°C, allowing quick processing.

For maintenance, the coating can be soldered through or removed using acetone, facilitating repair work. Due to flammable solvents in the formulation, usage in well-ventilated areas with ignition sources kept away is critical for safety.

This conformal coating finds key industrial applications in electronics manufacturing and repair, particularly in humidity-prone environments requiring high dielectric insulation and protection of electrical components such as transformers and coils to reduce noise and improve performance.

The coating has a low viscosity formula for easy aerosol spray application. It operates efficiently within a temperature range from -40°C to +60°C. Offers high dielectric strength exceeding 80kV/mm for superior electrical insulation.

Transparent finish preserves visibility of components while providing protective barrier. Suitable for protecting PCBs, transformers, ornaments, paints, furniture, and paper from moisture and corrosion. Compatible with various materials including metal, paper, and plastics with recommended preliminary compatibility tests.

Dries to touch in about 20 minutes at room temperature to expedite usage. Coating can be soldered through or removed with acetone for repair or maintenance. Contains flammable solvents; requires use in well-ventilated areas away from ignition sources.
