CHEMPROOF HB COATING epigen 4029

1 Designed as the ultimate chemical resistant high buildcoating, 4029 is based on high performance Novalac resintechnology, solventless in nature, to meet the highestpractical standards of chemical resistance and corrosionprotection a barrier COATING or lining suited to treatment ofsteel, concrete and brick in applications where acids,alkalis, organic solvents, or a number of chemicals inprocess give rise to problematic functionality and high cross linking density is thekey stone of 4029 which also contains a unique fill thatoffers high resistance to erosion and abrasion withoutcompromising chemical APPLICATIONSAcid BundsTanks & VesselsRail CarsScrubbersSteelwork CoatingPipelines & ValvesSolvent Extraction SystemsAcid Sumps & DrainsDucting SystemsAcid Fume Proof RoofingSulfur PitsConcrete RepairCHEMPROOF HB COATING epigen 4029 FEATURESS uperior Novalac polymer systemHighly erosion resistant fillApplication DFT up to 1000 micron in the one coatFree of all solvents - zero VOCO utstanding resistance to chemicals & acidsVersatility in application - can be used with GFSuitable in patching or repair of mortarPROFILER atio by weight2 parts A to 1 part B Pot Life minutes @ 24oC30 Mixed consistency @ 24oCViscous Flowable LiquidSpecific gravity when for 500 free

4 Thecure may be increased by heating product or by leavingmixed material stand for 15 minutes before use. The curemay be decreased by cooling the product before :2003/Marrev4,2011/SeptCHEMPROOF HB COATING epigen 4029 This information is supplied as an indicative reference should be used where direct comparisons are to be of product should be carried out using slow speedmixers and completed by adding to the part A , the part B . Ensure the mix is homogeneous and free from air can be applied either by airless spray, brush or it does not contain solvents, application by sprayallows the application of high film thicknesses in singlecoats, and ensures that all material purchased actuallycontributes to the final DFT. 4029 is a higher viscosity thanconventional solvent containing coatings and application mayrequire more specialised practices but is generallycompensated for by the speed of application and need toapply fewer Diluent maybe added to 4029 to control viscosityunder some circumstances.

5 Avoid excessive additions anddo not add Diluent in confined spaces or near naked not add thinners to extend pot concrete correction applications, blow holes, cracks, orsignificant damage maybe faired by mixing 1 part 4029 30/50 sand and applying the paste to the damagedareas. This practice should be employed after the first coatapplication when the extent of degradation becomesapparent and before second coat is a functional, industrial finish and is not developed topossess asthetic properties such as high gloss which wouldenable it to be used where appearance is PRODUCTSMANUFACTURED BYPeerless Industrial Systems Pty LtdABN 14 097 615 39179 Robinson Ave, Belmont, WA 6104PO Box 407, Cloverdale, WA 6985 Phone: (08) 9477 3788 Fax: (08) 9477 3766 Email.
