Epoxy Hardeners

Product Details:

Description: Jyoti 14401/ Jyoti Hardener 1200 is a two component, room temperature curing, polyurethane based casting resin system. Jyoti 14401 is a filled solventless, reddish brown coloured resin. Jyoti Hardener 1200 is an aromatic isocynate. Resin & hardener components on mixing cures by a polyaddition reaction at room temperature & gives flexible cured mass.

Areas of Application: Casting, potting and encapsulation of electrical & electronic components. Sealing of cable Joint on low & high voltage cables. Jyoti 14401 particularly has improved adhesion for cross linked polyethylene (XL PE) cables.

Properties of cured material:

• Jyoti 14401 + H 1200 cures with low volume shrinkage and low exotherm to give a stress-free cured mass. The elasticity of the cured casting resin produces extremely favourable temperature cycling behavior.
• The cured casting resin is further distinguished by good resistance to tracking. The resin system is suitable for use in electrical components working up to 120°C(Class E)

Application Method: The resin component Jyoti 14401 should be first stirred, since the filler on long storage has settling tendency. Jyoti 14401 & Jyoti Hardener 1200 should then be mixed in recommended proportion at room temperature (20 - 40°C) and used for casting or potting, within the potlife (usable life of mixture) Jyoti 14401 + Jyoti Hardener 1200 is a fast reactive system hence has limited pot life

Description: Jyoti 1520F/Hardener 17055/ Accelerator 1803M is a three component heat curing epoxy system. Jyoti 1520 F is a solventless liquid resin of medium viscosity based on bisphenol A. Hardener 17055 is yellow coloured low viscosity, modified carbolic anhydride type hardener. Accelerator 1803 M is amine based low viscosity, dark brown liquid. For most application addition of 2 or 3 more components such as flexibilizer EP09, silica filler & Jyoti (brown) are employed. The curing of epoxy system takes place at elevated temperature by poly addition reaction. The resultant cured mass is hard with excellent electrical insulation, mechanical and thermal properties.

Areas of Application :

• Casting & potting of high voltage coils, transformers and switchgear.
• Impregnation of instrument transformers.
• Binder for glass fibre fabric and filament wound tubes &laminates.

Properties of cured material: Jyoti 1520F system cures into hard & tough mass after curing at elevated temperature. The cured mass has good adhesion to metals and most plastics. The addition of fillers like silica. Alumina etc. improve heat conduction, mechanical properties and dimensional stability. The cured mass has excellent dielectric properties and track resistance. The resin system, in combination with other heat insulation material, is suitable for class F (155 degreeC) components & machines.

 

Application Method: 

• Jyoti 1520F system is best processed at warm temperatures of 50-600C It is best to make a premix of Jyoti 1520F + Flexibilizer EP09 + silica or other filler + Jyoti (brown) or other colour paste at 60 degreeC. To this premix Hardener 17055 and accelerator 1803M should be added last. The mixture is best processed at 60 degreeC for sufficiently long pot life and low processing viscosity. Mixing ratio as specified must be followed for best results.
• Mould used for casting must first be treats with a mould releasing agent. For this purpose, a baking finish of compound stored for 4-6 hours at 150 degreeC and polishing with silicone paste, thereafter, are best suited.

Description: Jyoti 1520 F is a solventless 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: 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 40 degreeC) 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 fillers: 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 degreeC 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 degree 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.
