Modifier Cover Flux

This is a modifying type of flux for Aluminum-Silicon alloys at low melting temperatures. The charge is melted under COVER FLUX SP-I & after required temperature is attained, degassing has to be performed with DEGASSER-SP-I. Rabble the surface of the melt & skim off the dross cleanly. Now sprinkle COVER FLUX SP-II about 3% by weight of metal over the cleaned surface. As soon as the flux layer liquefies, work well into the melt for 3-4 minutes by using tools. Now sprinkle another quantity of COVER FLUX SP-I on surface of melt & wait until the correct pouring temperature is reached. Finally skim off the metal free dross and pour the metal without delay. Packing: 50 packets of 1 kg. Packed in 50 kgs. Double Polylined Hessian sacks, which is solid enough to withstand shakes and jolts of transportation.
