React-Shun 1600 grams Direct Casting and Molding Barrier Liquid
This is the cost saving 1600 gram bottle of the famous React-Shun RP barrier liquid. It alters the chemistry of your investment at the interface of your RP part and mold cavity during burnout, creating an inert contact layer in the mold cavity. React-Shun will greatly reduce rough casting surfaces caused by the reactive chemistry of prototyping resins and gypsum bonded investment during burnout. You only need to dip your resin parts into the React-Shun solution 3 - 5 times to achieve fantastic results.You should blow off the excess with a light stream of compressed air between dips especially in the detail areas.Close your bottle as soon as you are finished dipping as this material dries very quickly.
