Room temperature curing epoxy potting

Shijiazhuang Li Ding Electronic Materials Co., Ltd. LD-202 a room temperature curing epoxy potting materials, the use of 1, who require infusion sealing, packaging protection, insulation or other proof of electronic products can be used; 2, is widely used transformers, aquarium equipment, AC capacitor, ignition coil, negative ion generator, ignition coil, power modules, electronic controllers and other electronic components potting; (3) does not apply to flexible or soft shell encapsulating products. Second, the appearance and characteristics of the project LD-202A LD-202B Viscosity (25oC cps) 12000-15000 45-55 specific gravity (25oC) 1.6 0.98 Color Black (can also be specified) light yellow - brown Third, use the LD-202 cured at room temperature epoxy potting A / B material at 100: 25 ratio, mixing, can the potting; if A high viscosity material, may be preheated at about 60 oC. As more bubbles, the bubble can vacuum off after potting. Four, LD-202 room temperature curing epoxy potting the curing process: 12 to 24 hours at room temperature or 60oC × 4 hours, or 80oC × 0.5 hours (can be adjusted according to user needs) Fifth, can be used at room temperature for one hour of time five, LD-202 at room temperature curing properties of cured epoxy potting of:? (25oC under test) Item Test Method Value volume resistivity (Ω.cm) GB1410-1989 ≥1.0 × 1015 Surface resistivity (Ω?? ) GB1410-1989? ≥1.0 × 1014 Electric strength (KV / mm) GB / T1408.1-1999? ≥20 shear strength (Kg / cm2) GB7124-1986 ≥80 flame retardant (grade) GB4609F V-0? ????????????????????????????????? Description: When the detection is sample preparation, curing process: room temperature curing × 12h + 60oC × 4h. Six confined conditions at room temperature shelf life of six months. The above information. ------------------------------- -------------------------------------- Address: High-tech District, Shijiazhuang City, Xiangjiang Road 319 Tianshan Technology Industrial Park 6-1-502 Tel: 18931865367
