Product Introduction
Araldite U6942/U001B is a polyurethane resin system specifically designed for the insulation and protection of electronic components. The system consists of resin U6942 and hardener U001B, with a mix ratio of 100:16 by weight and 100:20 by volume. It supports conventional vacuum casting or atmospheric pressure casting at room temperature, using a dosing and mixing machine for precise formulation. The product gels and polymerizes at room temperature, with accelerated polymerization possible under heat. Standard colors include white, black, and red. Resin U6942 is based on modified aliphatic polyols and filled with inert mineral fillers; hardener U001B is composed of diphenylmethane diisocyanate (MDI). Storage requires keeping at room temperature in original packaging for 12 months, with re-testing necessary after this period.
Enhanced Properties
The special properties of this product deepen the parameters from the first section. Firstly, it features a halogen-free formulation, ensuring environmental compatibility. Secondly, the document highlights its excellent thermal aging resistance, providing long-term stability in high-temperature environments. In terms of electrical properties, it offers good insulation characteristics (such as high volume resistivity and dielectric strength), but specific values (e.g., tensile strength, elongation at break, dielectric constant) are not provided in the document, so no relevant data is available. Usage properties include an initial mixture viscosity of 1100 mPa.s (at 25°C), gel time varying by color (60 minutes for white, 30 minutes for black), and cure time of 12-24 hours. Density and viscosity data are detailed in the table. Note that the final mechanical and electrical property test standards (e.g., ISO 37:2004, IEC 60243-1) are listed, but measured values are missing; thus, properties are confirmed to exist but numerical data cannot be provided.
Application Scenarios
The application scenarios for Araldite U6942/U001B are primarily based on the fields specified in the document: for insulating and protecting low-voltage transformers, filters, capacitors, and electronic components. For the same product model, specific applications include: potting in low-voltage transformers to provide moisture and mechanical protection, extending device lifespan; encapsulation in industrial filters to suppress electromagnetic interference and enhance durability; use in automotive electronics capacitors for temperature stability and electrical insulation, suitable for electric vehicle charging systems; and protection of sensitive components in consumer electronics (e.g., power adapters) against environmental stress. The imagined scenarios derive from industry knowledge: this resin system, due to its rapid room-temperature curing and good electrical properties, is commonly used in renewable energy equipment (e.g., solar inverters) and industrial control system component encapsulation.
