128A Standard Grade Liquid Epoxy Resin

The 128A Standard Grade Liquid Epoxy Resin is a classic bisphenol A liquid resin offering a stable epoxy value with balanced mechanical performance, electrical insulation, and chemical resistance — one of the most widely used general-purpose base resins in industrial applications.

Unlike the 128A+ Electronic and Coating grades, which are optimized for specific performance targets, the 128A Standard Grade is designed to deliver the best balance between formulation versatility and cost efficiency across a broad range of industrial scenarios. It is compatible with amine, anhydride, and polyamide curing agents, as well as a wide variety of fillers and additives, enabling flexible formulation as potting compounds, adhesives, coating vehicles, or composite matrices.

Moderate viscosity supports both manual and mechanized application, with ambient or mid-temperature cure options and a practical pot life for production environments. Manufactured under a mature, large-scale process, it provides consistent batch quality, making it the go-to base material for performance-conscious, budget-sensitive industrial projects.

Typical applications: general-purpose electronic component encapsulation and PCB insulation; industrial anti-corrosion coatings and structural adhesives; fiberglass and carbon fiber composite molding; civil concrete repair and waterproof sealing.
