[. . . ] Many Scotchcast powder resins are also recognized by UL as component insulation of class B per UL 746B. These are listed in UL file E35075 (QMFZ2). 3 Powder Resins Typical Property Data Temp Class B F H Product Number 260 260CG Description This widely used, well known product is used primarily in spray and fluid bed dip applications. Coarse ground version of 260 for improved fluidized bed performance. Also available in a faster cure version designated 260 8G. Cure data listed is for standard version. This resin has excellent flow characteristics which produce a uniform coating in applications such as resistance heated bobbin wound coils. It is used primarily in spray and fluid bed dip applications. 263 is used primarily in spray and fluid bed dip applications and has been designed for use where high temperature cut-through resistance is required. Low melt viscosity and minimum build make this unfilled powder ideal for a variety of coating, bonding and impregnating applications, notably coating from a solvent. 266 is specially formulated for application using the electrostatic fluid bed or spray process, but can be used with conventional fluid beds also. It is similar in color to 3MTM ScotchcastTM 260 resin and features improved impact resistance. Also available in a blue/green version designated 266 TC. This product accepts a charge very easily, which makes it ideal for electrostatic coating techniques. This product is designed to permit the thin coating of cold as well as heated parts such as capacitor cans, transformer covers, and resistors. 5230N has superior charging capabilities and is designed to provide smooth uniform coatings using the electrostatic fluid bed application method. Formulated specifically for use in the electrostatic fluid bed process, 5388 provides superior cut-through resistance as well as excellent heat, chemical and moisture resistance.
