Technical Data SheetPage 1September 2014Emer-Seal CRHighly chemical resistant, fast cure, durable, one-component joint sealantUsesSealing joints in: Chemical bund areas Floor joints in chemical processing plants Concrete joints exposed to acid spillage Swimming pools Sewage processing tanks Food, wine and citrus processing areasAdvantages Ready to use Fast rate of cure Long life weathering resistance Highly resistant to biological attack Highly resistant to a wide range of chemicals including strong acids and alkalis Highly resistant to pool chlorine, salt water chlorination and ozone treatment Potable water AS4020 certification Compatible with Durafloor N protection systems for concreteDescriptionEmer-Seal CR is a one part, gun applied non sag joint sealant designed for sealing expansion and construction joints exposed to aggressive chemical environments. Emer-Seal CR utilises unique polymer technology which provides outstanding chemical resistance and cures by reaction with atmospheric moisture to form a tough flexible seal. Once cured, Emer-Seal CR is resistant to attack from most of the aggressive chemicals used in the food, mining and chemical processing industries. Technical SupportParchem offers a comprehensive range of high performance, high quality construction products. In addition, Parchem offers a technical support package to specifiers, end-users and contractors, as well as on-site technical CriteriaEmer-Seal CR may be applied to joints between 8 mm and 50 mm wide. To minimise stresses imposed on the joint sealant, all moving joints should be designed to an optimum width to depth ratio of 2:1. This ratio is subject to the following overriding minimum sealant depths: 8 mm minimum sealant depth on non-porous surfaces 12 mm minimum sealant depth on porous surfaces such as concrete and masonry 20 mm minimum sealant depth in applications where the sealant is subject to a hydrostatic pressure or trafficCare must be taken to ensure joint movement does not exceed the sealant s movement accommodation uncertain about any of the design criteria, contact your local Parchem branch for further quoted is typical for this product but does not constitute a :Non slump, thixotropic pasteHardness: - Shore A:32 5Tensile modulus: 100% elongation: 100% Ultimate elongation: MPa @ 100% > MPa @ >400% Colours:Concrete Grey, Pool Blue Other colours to batch orderPhysical or chemical change:Chemical cure, moisture activatedApplication temperature:Minimum 5 CService temperature:Minus 50 C - 150 CTooling time:20 minutes @ 25 C 65% RHCure rate: Approx 3 mm in 24 hours, then 1 mm / day @ 25 C / 65%RHMovement accommodation factor: 25% butt joints (50% total)Chemical resistance - continuous immersion - (worst case testing - 6 months exposure)* Important: Ensure that Emer-Seal CR is fully cured before it is subjected to chemical exposure.

The joint sealant must be capable of accommodating +/- 25% joint movement and should be accompanied by data confirming the level of resistance of the sealant to the chemicals in question. Joint preparation, priming and sealant application must be in strict accordance with the current technical joint sealant must be manufactured in Australia by an ISO9001 accredited supplier. The joint sealant must be installed by a contractor nominated by the CR supplied by Parchem is such a InstructionsJoint preparation Ensure that all joint dimensions are as specified, and that the anticipated joint movement is within the movement accommodation capability of Emer-Seal CR. New concrete must be allowed to cure for a minimum of 28 days before sealant installation. Joint faces must be sound and completely dry, clean and frost free. Oil, grease, curing compounds, form release agents, and all surface contaminants must be completely removed by grinding the joint faces or by using Parchem breakers and joint fillersJoints subject to hydrostatic pressure must have the sealant supported by a suitable rigid joint filler such as Parchem Hydrocor. Joints subject to hydrostatic pressure must also contain a suitable waterstop such as a Fosroc Supercast joints not subject to hydrostatic pressure, a backing rod such as Expandafoam Backing Rod may be used. In formed joints a polyethylene bond breaker tape must be used to prevent sealant from adhering to the back face of the : do NOT use masking tape, electrical insulation tape or Gafa tape as a bond breaker tape. Emer-Seal CR may bond to the tapes and result in the failure of the joint joint surfaces must be sound and free from any trace of surface Emer-Seal CR offers very good adhesion to concrete and masonry, the agressive nature of the chemicals that come into contact with the sealant demand that primers be used on masonry substrates. Priming is not normally required on solvent cleaned glass (use only Parchem Solvent for cleaning), ceramic and metal surfaces. Where metal surfaces are treated with paints or other organic coatings, adhesion testing is recommended to ensure that adequate adhesion will be and masonry surfaces must be primed with Primer 13, a two component epoxy primer which combines excellent chemical resistance with good hydrolytic stability, making this primer ideal for use in demanding chemical resistance applications. Emer-Seal CR used in conjunction with Primer 13 is suitable for use in permanently water immersed applications. Primer 13 must be touch dry before applying Emer-Seal CR advice on other applications, or where Emer-Seal CR is to be used with other substrates, contact your nearest Parchem sales CRPage 3Parchem Construction Supplies Pty Ltd7 Lucca Road, Wyong NSW 2259Phone: 1300 737 80 069 961 968Distributed in New Zealand by: Concrete Plus Ltd23 Watts Rd, Sockburn 8042 Ph: 03 343 0090Important noticeA Safety Data Sheet (SDS) and Technical Data Sheet (TDS) are available from the Parchem website or upon request from the nearest Parchem sales office.

Parchem does not accept any liability either directly or indirectly for any losses suffered in connection with the use or application of the product whether or not in accordance with any advice, specification, recommendation or information given by CRApplicationFit the sausage of Emer-Seal CR into a suitable sausage gun and gun firmly into the joint. Ensure that the sealant is forced well against all joint surfaces to achieve good surface wetting and thus optimum adhesion. Guide the nozzle along the joint gradually, applying even pressure to the trigger. The joint must be filled completely at all after application the sealant should be tooled. Use a smooth tool to produce both the required surface finish and to assist in further forcing the sealant into good contact with the joint faces. The use of use soapy water as a tooling aid is not recommended as the cure of the sealant may be adversely upEquipment should be cleaned promptly by wiping with Parchem Solvent, as cured sealant is very difficult to remove. Cured sealant can only be removed by mechanical methods. Soaking the equipment in Parchem Solvent makes removal of cured sealant sealants such as Emer-Seal CR should not be applied in direct contact with bituminous materials. Emer-Seal CR is not designed to provide resistance to organic solvents. Contact Parchem for advice if organic solvent resistance is Chlorine containing trichloroisocyanuric acid may cause the breakdown of surface layers of Emer-Seal CR. Also, crystallized deposits may form on the surface of the sealant from reaction of the above trichloroisocyanuric acid and urea if regular pool cleaning is not CR has been tested for resistance to many chemicals including Sulphuric Acid, Hydrochloric Acid and Caustic solutions.
