S e c t i o n 1 5 - P a g e 3 May 2013 EZ-MUD ® PLUS Polymer Emulsion Description EZ-MUD PLUS is a high molecular weight version of EZ-MUD with impr oved pr operties. EZ-MUD PLUS, a liquid polymer emulsion containing partially hydr olyzed polyacrylamide/polyacrylate (PHP A) copolymer , is used primarily as a viscosifer and bor ehole stabilizer to pr event r eactive shales and clays fr om swelling and sloughing. The liquid form makes mixing easy . EZ-MUD PLUS is also added to low-solids drilling uids to incr ease lubricity and to impr ove the carrying capacity of air/foam injection uids. Applications/Functions • Stabilize r eactive shale and clay formations • Impr ove bor ehole and excavation stability • Enhance slurry rheological pr operties • Alleviate mud rings, bit balling and booting-of f in clay formations • Reduce drill pipe tor que and pumping pr essur e • Minimize ro d chatter in diamond cor e drilling • Cr eate “stif f-foam” and maintain foam integrity • Flocculate non-r eactive solids in r everse pit at low concentrations Advantages • Mixes easily with minimum shear in fr esh water • Ef fcient shale/clay stabilizer and viscosifer • Non-fermenting • Cost ef fective - small amounts pr oduce desir ed r esults • Br eaks down chemically with bleach (sodium hypochlorite) • NSF/ANSI Standar d 60 Certifed Notes • Make-up water used to mix EZ-MUD PLUS should meet the following quality: W ater pH between 8.5 - 9.5 • Reduce total har dness of make-up water by adding soda ash (sodium carbonate) at 0.5 to 1 pound per 100 gallons (0.6 – 1.2 kg/m 3 ) of make-up water . • EZ-MUD PLUS can be chemically br oken down with liquid bleach in r egular household concentration (5sodium hypochlorite). Use one gallon of liquid bleach per 100 gallons (10 liters/m 3 ) of uid formulated with EZ-MUD PLUS. Do not use perfumed liquid bleach or solid calcium hypochlorite. www .dsiundergr ound.com
