JYOTI 1520 F is a solvent less unfilled epoxy resin which in combination with JYOTI HARDENER 1408 cures in to a hard mass. JYOTI HARDENER 1408 is a low viscosity polyamide liquid hardener. The curing of the resin compounds is a polyaddition reaction which occurs at room temperature.
AREAS OF APPLICATION : HARDENER 1408 HARDNER
Applications of JYOTI 1520 F in combination with JYOTI HARDENER 1408 are –
- Casting, potting, sealing & binding of small & medium sized electrical and electronic components.
PROPERTIES OF CURED MATERIAL
JYOTI 1520F + JYOTI HARDENER 1408 system is characterized by low viscosity & fast curing at ambient temperature. The hard cured mass has good mechanical, electrical, & chemical properties. The resin system can be used with filler loading. The resin/hardener combination is used in electrical components of thermal class 120 (class E).
APPLICATION METHOD
JYOTI 1520 F & JYOTI HARDENER 1408 should be mixed well at room temperature (20 to 40ºC) and used within pot life of mixture. The resin & hardener mixture is then use for intended application. Contaminated tools & containers can be cleaned with Thinner 221 before the resin system starts hardening.
ADDITION OF FILLER
Dried fillers such as silica, talc, dolomite, 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 1520 F under vacuum preferably at 50-60°C. Mould used for casting must first be treat with a mould releasing agent. For this purpose, a baking finish of compound stored for 4-6 hours at 150°C & polishing with silicone paste, thereafter is best suited.
