jER™ 4250
jER™ 4250 is a solid epoxy resin from bisphenol A/bisphenol F with a high molecular weight and softening points. It can be used for PCM, CAN, and other coatings and adhesives as it contributes excellent insulation and heat, chemical, and water resistance.
jER™ 4250 is a solid hybrid epoxy resin made from a 50:50 mixture of bisphenol A-type with bisphenol F-type epoxy. It can create toughness and film/sheet formability upon the addition of a polymer epoxy resin. It also contributes insulating and vapor barrier properties; resistance to heat, water, and chemicals; and excellent wear and abrasion resistance when used in a variety of applications, including PCM and CAN coatings, paints and coatings, thermoplastics, printed electronics, plastic processing, and CFRPs.
Bisphenol A/bisphenol F epoxy resin High molecular weight High softening points Highly adhesive to metal, porcelain, concrete Excellent insulation High heat resistance High chemical resistance Excellent wear and abrasion resistance High water resistance Flexible Low viscosity makes it excellent to work with Toughness and film/sheet formability Insulating Vapor barrier properties
Problems Solved
Damage to coatings caused by exposure to weather, chemicals, or water Resin shifting or distortion from water Cracking and surface defects of coatings used on flexible substrates
Applications
Coatings (PCM, CAN, etc.) and adhesives Highly adhesive to metal, porcelain, and concrete Paint and coating: additives to improve paintability/coatability Thermoplastics Printed electronics Plastic processing CFRP: additives to give toughness/flexibility
