SFP MICAWASH NO. 15 is the original and finest ladle wash developed for non-ferrous metal casting industry. \u00a0Micawash No. 15 is water based refractory coating used for prevention of iron (Fe) pick-up by low melting alloys from melting vessels and handling tools. Specifically, this coating is applied on ladles, crucibles, pots, runners, dies and on tools as skimmers, sampling spoons etc. The two main functions of this wash are:<\/p>\n
\u2022\u00a0To ensure a clean and uncontaminated quality casting
\n\u2022\u00a0To protect and prolong ladle\/tool working life<\/p>\n
Directions for Preparation <\/strong> 1. For spraying – mix 3 pounds of powder with one U.S. gallon (3.78 L) water Preferably allow the prepared coating to stand for a few hours prior to use, and keep well stirred before application. Dry container or tool thoroughly before using. This mixing formula is a guide. More or less solids can be used depending on your requirements.<\/p>\n Application<\/strong> Packaging <\/strong> <\/p>\n SFP R-20 COATING is an odorless, dry, reddish powder consisting of complex inorganic minerals and refractory oxides.

\nSFP MICAWASH NO. 15 is sold as a powder to be mixed with water.<\/p>\n
\n2. For dipping or brushing – mix 4 pounds of powder with one U.S. gallon (3.78 L) water<\/p>\n
\nWhere a firmer adherence of the coating is desired, add up to 5% of sodium silicate (water glass) by weight to the micawash mixture. This coating is also recommended for zinc (Zn) and lead (Pb) melting. It is applied to room temperature ladles. The ladles may be new or used. It can be re-applied to a ladle that has had the coating chipped or worn off. After applying, the ladle is set on the furnace apron or furnace roof to dry for about two hours. The coating may last all week if it is not chipped or damaged. Typically ladles are changed every 24 hours. The used ones should be recoated until the ladle itself is worn through.<\/p>\n

\n\u2022 Preventing iron pick-up from ferrous tools, pots, ladles etc. during the melting, treating and handling of light and non-ferrous alloys.
\n\u2022 Easing the removal of metal skulls from tools, pots, ladles and launders etc.
\n\u2022 Coating permanent molds in areas (such as risers and gates) where the insulating properties of the coating are desirable to delay the solidification time of the molten metal.
\n\u2022 Preventing interaction between molten metal and materials with which they come into contact at temperatures up to 1900\u00b0F<\/p>\n
\n\u2022 1 pound of R-20 to 1 gallon of tepid water
\n\u2022 Stir and heat the mixture to the boiling point
\n\u2022 Add 4 to 6 ounces of a 2:1 ratio sodium silicate (water glass) to this mixture
\n\u2022 Stir, while boiling, until homogeneous
\n\u2022 Allow to cool
\n\u2022 Apply to warm (200\u00b0F \u2013 400\u00b0F) tools, pots, ladles etc. by spraying, painting or dipping<\/p>\n
\nEnsure the coating is thoroughly dry before using with molten metal.<\/p>\n
