jER™ YX4000
jER™ YX4000 is a highly adhesive, bisphenol-type solid epoxy resin with significantly low melt viscosity, low water absorption, and rigidity against stress. It is used as the standard for EMC thin-package applications and electrical applications.
jER™ YX4000 is a bisphenol-type solid epoxy resin made from the reaction of epichlorohydrin and tetramethyl bisphenol. It has a significantly low melt viscosity, low water absorption, and good adhesive and rigidity balance against stress, making it appropriate for applications such as electrical and electronic, thin-package EMC, potting and encapsulation materials, powder coatings for ship bottoms, adhesives, and composites. It also exhibits excellent abrasion, good adhesion, and heat, wear, water, and electrical resistance.
Specifications
Epoxy equivalent weight (WPE): 180–192 g/eq Melting point (°C): 108 Appearance: Yellow solid Harsh hydrolyzable Cl: 400 ppm Density at 25°C: 1.15 g/cm3
Bisphenol-type solid epoxy resin Abrasion, heat, and water resistance Electrical insulation Wear resistance Significantly low melt viscosity Low chlorine content Low water absorption Good balance between adhesiveness and rigidity against stress Highly adhesive to metal, porcelain, and concrete
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
Compatible with metal, aluminum, concrete, masonry, glass, fibers, fabrics, plastics, steel, and ceramic Electrical and electronic applications (EMC, solder resist, PCB) Highly adhesive to metal, porcelain, and concrete Potting and encapsulation materials Powder coatings for ship bottoms Adhesives Composites Thin-package EMC as de facto standard
