Product Description

Product Description

61003A is a newly developed modified epoxy acrylate resin engineered for high-end photocurable applications, breaking through the technical bottlenecks of traditional epoxy acrylates which often suffer from brittleness and yellowing despite their fast curing speeds. Through molecular structure optimization, this product maintains extremely high photocuring reactivity while imparting excellent flexibility, impact resistance, and significantly enhanced UV aging resistance to the coating. As a primary resin for UV potting compounds, it effectively protects precision electronic components from stress cracking and environmental erosion; as a base for UV varnishes, it delivers lasting high gloss and transparency, making it widely applicable in industrial coatings and electronic encapsulation fields with stringent requirements for weatherability and mechanical performance.
