Unaffected by water immersion after curing Hardness Shore A: Typically 25 Movement accommodation factor: Maximum 60% for butt joints ( ± 30% ) Flammability: Burns, but does not readily support combustion. Note that toxic fumes may be generated if product is burned Chemical resistance: Resistant to dilute acids and alkalis to occasional spillage and aliphatic solvents (Avgas, petrol etc.) Not resistant to aromatic or oxygenated solvents Specification Clauses “Where so designated on the drawing, joints are to be sealed with Emer-Seal 200 two part polyurethane sealant, manufactured by Parchem. All parties involved in the project and the installation of the sealant must read and understand the technical data sheet before installing the sealant. Joint preparation, sealant mixing and application must be in strict accordance with the manufacturer’s instructions and preferably be installed by an experienced contractor. Storage shelf life is 3 months when stored in unopened original containers in dry conditions, between 5°C and 30°C. Applications Instructions Joint preparation Ensure that joint dimensions are as specified, and that anticipated joint movement is within the capability of the Movement Accommodation Factor of Emer-Seal 200. Concrete should have been allowed to cure for at least 28 days. Remove all dirt, dust, laitance and loose material from concrete by vigorous wire brushing or grinding. Remove all rust, scale and protective coating from metal surfaces, and clean off any oil or grease using Solvent 10. Joint faces in concrete must be sound, flat and free of surface irregularities and completely dry, clean and frost free. Be wary of any excess moisture in the bottom of the joint ie from any expansion joint filler’s or ponding of water, it is imperative the joint must be completely dry prior to application of the primer and sealant, the applied primer must not be exposed to any moisture prior to the application of the sealant itself. Any joint faces which do not meet these requirements may require forming of a fresh joint surface by saw cutting or refacing with a suitable epoxy mortar. For a particularly neat finish, cover the face edges of the joint with masking tape before priming. Prime joint as detailed below, inserting bond breaker and/or backing material when appropriate. Priming masonry surfaces Use Primer 13. This is a two part epoxy surface primer with exceptionally good hydrolytic stability which ensures good adhesion of Emer-Seal 200 to the substrate under prolonged submerged conditions. The ambient and substrate temperature needs to be above 5oC before and after the application of the primer. Mix the two components of the primer by pouring the Hardener component into the Resin component, mix thoroughly for a minimum of one minute by stirring with a spatula, paint stirrer etc. Apply an even coat of primer by brush onto the bonding faces of the concrete, the base of the joint should have no primer residue present after the primer has been applied, then allow the primer to become touch dry before applying any sealant ( typically 1 hour at 23°C). DO NOT APPLY SEALANT TO TACKY OR WET PRIMER. The sealant must be applied within 8 hours at normal temperatures - within 3 hours at elevated temperatures (above 30°C). The pot life (usable life) of mixed Primer 13 is 30 minutes @ 23°C and 20 minutes @ 30°C. Any unused mixed Primer 13 should be discarded after the pot life has expired. Priming metallic surfaces Use Primer 4 on clean rust free ferrous metal. Consult the Technical Services Department for treatment of stainless steel. Apply primer and allow to dry for a minimum of one hour but not longer than eight hours prior to application of Emer-Seal 200. Emer-Seal® 200
