JYOTI FIL 160 is an off white colored filled, solvent less epoxy compound. JYOTI FIL 160 is a specially formulated and processed to obtain void free casting, potting encapsulated components. It contains specially selected and processed fillers incorporated under vacuum mixing & has lower abrasive nature. It is ready to use filled system having low viscosity at processing temperature. JYOTI FIL 160 can be used with JYOTI Hardener 1760 as a heat curing system.
JYOTI FIL 160 in combination with JYOTI Hardener 1760 has the following characteristics:
- Good adhesion to most organic and inorganic materials
- Good mechanical and electrical properties combined with good chemical and water resistance
- Fast curing
- Low coefficient of linear expansion
- Increased thermal conductivity
AREAS OF APPLICATION : HARDENER 1760 HARDNER
JYOTI FIL 160 in combination with JYOTI Hardener 1760 is suitable for: –
- Casting, potting and sealing of small & medium sized electrical electronic components.
- Casting of switch gear components and insulators
- Potting of instrument transformers
- Application where moderate curing temperatures are of advantage
- Topping of capacitors as sealant
PROPERTIES OF CURED MATERIAL
The cured mass of JYOTI FIL 160+ JYOTI Hardener 1760 shows good mechanical, electrical & chemical properties. Because of special type of fillers in JYOTI FIL 160, the cured mass shows good thermal shock resistance, reduced shrinkage, low coefficient of thermal expansion & increased thermal conductivity. The combination of JYOTI FIL 160, JYOTI Hardener 1760 is used in thermal class 155 (class F) electrical components.
APPLICATION METHOD
JYOTI FIL 160 contains filler, which have tendency to settle on long storage. JYOTI FIL 160, should therefore, be stirred to a homogenous mixture, each time it is drawn from the container. JYOTI Hardener 1760 should be melted separately. The molten JYOTI Hardener 1760 shall be added in JYOTI FIL 160, which is maintained at about 60-70°C. Both the components shall be mixed thoroughly. For longer pot life, cool the mixture to room temperature immediately
ADDITION OF FILLER
Dried, moisture free fillers such as silica, talc, dolomite, and mica can be incorporated depending upon the performance requirement. Fillers shall be dried in oven at 150-200°C for 4-6 hours to remove moisture. Wherever vacuum mixing facilities are available, fillers may be added to JYOTI FIL 160 under vacuum preferable at 50-60°C.
