ELECTROLUBE DCRT High-Solids Modified Conformal Coating Enhances PCB Protection in Demanding Environments

In the fields of automotive electronics, aerospace, and defense, Printed Circuit Boards (PCBs) often face multiple challenges such as extreme temperature fluctuations, chemical corrosion, and mechanical shock. To meet the protection needs in these harsh environments, the globally renowned electronic chemical manufacturer ELECTROLUBE officially launches its DCRT series High-Build Modified Conformal Coating (SCC3). With a solid content of up to 70% and excellent physical and chemical properties, this product provides a rock-solid protective barrier for electronic components with complex geometries.

DCRT is a higher viscosity version of the DCR series, specifically designed to tackle hard-to-coat areas. Its unique modified alkyd resin formula not only gives the coating excellent rheological properties but also ensures perfect encapsulation on sharp edges, lead ends, and high-density component surfaces. Compared to traditional coatings, DCRT significantly reduces the phenomenon of "edge crawl" and can form a uniformly thick and dense protective film (typically 50-75 microns).

Moreover, the coating features an opaque red design. This not only helps identify coated areas during production but also effectively conceals the original design layout of the PCB, serving a certain degree of commercial confidentiality and anti-counterfeiting purposes.

According to the latest Technical Data Sheet (TDS), DCRT demonstrates remarkable environmental adaptability after curing:

• Wide Operating Temperature Range: Within the extreme temperature range of -70°C to +200°C, the coating maintains good flexibility and electrical properties, meeting strict thermal cycling test standards (IPC-CC-830).
• Excellent Electrical Insulation: With a dielectric strength of up to 90 kV/mm and a surface insulation resistance of 1×10¹⁵ ohms, it provides reliable safety for high-voltage environments.
• Strong Chemical Corrosion Resistance: After undergoing the recommended heat curing process (up to 120°C), DCRT resists erosion from various solvents, fuels, and hydraulic oils commonly found in the aerospace and automotive industries. It is also self-extinguishing, complying with UL746C safety standards.

Thanks to its versatile process adaptability, DCRT can be applied via dipping, brushing, and other methods, widely used in the following key scenarios:

• Automotive Electronics (EV & ADAS): In EV onboard chargers, Battery Management Systems (BMS), and control boards for Advanced Driver Assistance Systems (ADAS), DCRT effectively resists high temperatures in engine compartments and road salt spray moisture.
• Aerospace & Defense: For flight control systems and military radar power modules, DCRT's high-altitude adhesion and resistance to extreme temperature differences ensure long-term stable operation of equipment in environments ranging from high altitudes to deserts.
• Industrial Control & Energy: In charging pile control modules exposed to harsh outdoor climates, DCRT's moisture-proof and anti-mildew properties significantly extend equipment maintenance intervals.

ELECTROLUBE DCRT strictly complies with the RoHS-2 (2011/65/EU) directive and contains no hazardous substances. Meanwhile, considering the practical needs of production rework, the cured coating can be safely stripped using Electrolube's specialized removal gel (CCRG), greatly reducing scrap costs and enhancing production line flexibility.

As electronic manufacturing evolves towards high density and miniaturization, the requirements for PCB protection materials are becoming increasingly stringent. The launch of ELECTROLUBE DCRT undoubtedly provides designers and manufacturers of high-reliability electronic products with an ideal solution that combines high performance with cost-effectiveness.
