JYOTI 1520 F is a solvent less unfilled epoxy resin which in combination with JYOTI 1758 cures in to a hard mass. JYOTI 1758 is a low viscosity, pale yellow, clear, polyamine based liquid. The curing of the resin compounds is a polyaddition reaction which occurs at room temperature.
AREAS OF APPLICATION : JYOTI 1520 EPOXY RESIN
JYOTI 1520 F + JYOTI 1758 system is suggested for:
- Binder resin for FRP lining & FRB component manufacture with excellent chemical resistant properties.
- Corrosion resistant finishing coat on mild steel & concrete structures.
PROPERTIES OF CURED MATERIAL
JYOTI 1520F + JYOTI 1758 systems are 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 higher filler loading. The resin/hardener combination is used in electrical components of thermal class 120 (class E).
APPLICATION METHOD
JYOTI 1520 F & JYOTI 1758 should be mixed well at room temperature (20 to 40°C) and used within 30 to 40 minutes, depending upon the temperature and quantity of mixture. The resin & hardener mixture is then use for intended application. Contaminated tools & containers can be cleaned with Thinner 1221, 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 1504 under vacuum preferably at 50-60°C. 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°C and polishing with silicone paste, thereafter, is best suited.
