6202 (HT6202T) Epoxy encapsulation electronic components , black potting compound

6202 (HT6202T) double component heat curing epoxy potting adhesive is for Automobile ignition coil potting202 (HT6202T) double component heat curing epoxy potting adhesive is two components, heating curing, translucent, automobile ignition coil epoxy adhesive. Low viscosity, easy penetration of defoaming, permeability is good, cracking resistance is good , insulating property good, high temperature resistant.Typical ApplicationsAutomobile ignition coil pottingCharacteristic before curingRepresentative value rangeA componentColor GreyDensity g/cm3(25℃) 1.85 1.82～1.88(GB/T13354-1992)Viscosity mpa.s(25℃)400000 300000～500000GB/T 2794-1995B componentColor YellowDensity g/cm3(25℃) 1.15 1.10～1.20(GB/T13354-1992)Viscosity mpa.s(40℃) 60 40～70(GB/T 2794-1995)Characteristic after mixingColor GreyWeight ratio A:B =100:28Volume ratio A:B =100:44Operation time 130g GB/T 7123.1-2002) ≥75Condition of cure min(90℃,130g) 90℃@3h+130℃@3hCharacteristic after curingHarness: Shore-D(GB/T 531-1999) 92Glass-transition temperature℃ 142GB/T 11998-1989Volume Resistivity Ω·cm(25℃) 1.0×1015GB/T1692-1992Dielectric Strength KV/mm(25℃)(GB/T1692-1992) ≥25Bending strength: Mpa 105shock strength KJ/m2,(GB/T 1843-2008) 2.7Shear strength Mpa(GB/T13930)≥7Dielectric constant(25℃,1.2MHz,GB/T1692-1992)3.8dielectric dissipation factor(25℃,1.2MHz) 0.012GB/T1692-1992Thermal conductivity W/m.K(25℃)(GB/T 11025-1989) 0.6water absorption %(ISO 62) ＜0.1Work Temperature℃ -40～150Direction for use1. 1 glue injection: 90 ~ 100 ℃ preheated A component 2～3 hour(make sure adhesive hot enough, viscosity is low),Stir evenly inhaled or into the vacuum tank with agitator (Semi automatic filling and sealing potting process must first accurate weighing A component and then poured into tank). 80 ~ 90 ℃ while stirring vacuum for 2 to 3 hours(to no bubbles),keep warm and waiting to use.A. semi automatic filling and sealing process: accurate weighing in component B, A:B =100:28,poured into which vacuum tank loaded accurately weighing A components,60 ~ 65 ℃ while stirring vacuum for 30 minutes,until no bubbles. Potting process begin, after potting Put in the oven to curing.B. Automatic filling and sealing process:poured B component into which vacuum tank loaded accurately weighing A components, 35 ~ 45 ℃ while stirring vacuum for 30 minutes. Then adjust the A component and the B component of the discharge ratio(Weight ratio A:B =100:28；Volume ratio A:B =100:44),after ratio adjust, start inject adhesive,keep the temperature 60～65℃.After adhesive injection, put in the oven to curing.2.Curing:put in 90℃ oven 3 hours, and slowly warming up to 130℃(warming up time keep in 30～40 minutes),curing in 130℃ 2.5～3 hours,after curing slowly cooling to 50℃, and take it out of oven(cooling time keep in 60 minutes).AttentionEvery time mix adhesive need keep in 5-10KGS,mixed adhesive should finish used in 1 hour. The Vacuum degree of vacuum tank and vacuum room should as low as possible.Packing41kg/SetA component 32kg/bucket. B component 9kg/bucketStorageStore it in dry and shady places at the temperature of 8~28℃.Storage life 12 months
