The use of rubber gloves and a face shield is recommended when handling the product. Bitumen Standards & Grades Standardizing Bodies. Repeated or prolonged exposure may cause conjunctivitis. It makes up from 50 to 75% of the emulsion, although, in most cases, the range is from 55 to 70%. Asphalt emulsions are no exception. Anionic, non-ionic and cationic emulsifiers are all available, which will successfully emulsify bitumen and provide storage stable emulsions. Variables in emulsion production include the base bitumen and the type and amount of emulsifying agent. USES: GemSeal® Tack Coat asphalt emulsion is used as a general-purpose tack emulsion and bonding agent between new bituminous asphalt and old. Other Hazards. Anionic Emulsions R&G SDS Number: 003 _____ SAFETY DATA SHEET Section 1: Identification of product / manufacturer / utilization Product form: Liquid Product name: SS-1h, OKSS-1h, RS-1, RS-2, Tac oil, Fog Seal, CRO, Chip Seal Oil Synonyms: Anionic Asphalt Emulsion Manufacturer Reed & Graham, Inc. What are the requirement of utilities and overheads for setting up Bitumen Emulsion Production plant? 17. Specific hazards from combustion: Asphalt Emulsion is not a combustible liquid per the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard. TEGO® Addibit F4 HB. " It is a dispersion of small droplets of penetration grade asphalt cement in water with the aid of an emulsifier. Types of Bitumen Emulsions. Nonionic surfactants are rarely used alone due to their inferior efficiency in creating stable emulsions in comparison to anionic surfactants. Carefully review the (M)SDS below to see if it's the version you're looking for. Bitumen Emulsion Production plant ? 14. It very often requires some enhancement through modification with high performance polymers. Use in asphalt overlays, patching asphalt pavements to promote proper bond and prevent slippage between pavement layers. emulsion stored at depots), analysis of results (including run charts) and a requirement for a copy of the results to be forwarded promptly to Transport and Main Roads, and c) Ensure material supplied from depots can be traced to the production batch and associated. In the case of anionic emulsions, the chemical charge is negative. 1 Product identifier Product name ANIONIC BITUMEN EMULSION Synonym(s) ANIONIC SLOW SET • ASS 60 • ASS/170 - 60 • GROWMULCH 1. 5 t/h The bitumenemulsion plants is designated to prepare the cationic bitumen emulsion withrapid break STAS 8877-72 and the anionic bitumen emulsion, used in general for the cold application in the construction, maintaining and repairing roads. Application: Tack Coat RS-1 cationic bitumen emulsion can be used at ambient temperature at the spray rate of 0. 4% Sodium hydroxide 0. They develop adhesion rapidly between bitumen and aggregate. Safety Data Sheet Anionic Bitumen emulsions (SS 60) Version 3. The polymer expressed as the % on the bitumen. Bitumen emulsions are created when bitumen and water are mixed together with the aid of an emulsifier. 1 Asphalt Emulsions The asphalt emulsions employed for scrub seals should be slow to medium setting an-ionic or cationic SS-1, SS-1H, CSS-1, CSS-1H; ASTM specifications for anionic (SS) emulsions are listed in D977 and for cationic (CSS) emulsions in D2397. However, as the bitumen is an oil based good it doesn't blend with water and as it is sticky in nature, it doesn't effectively gets broke down into fine beads. Bitumen emulsion is produced by the suspension of ultra-fine particles of bitumen in water by the aid of emulsifier, a chemical additive, and is widely used in road construction - known as cold asphalt - and maintenance.
