Specification of Bitumen CMS
Bitumen CMS is typically produced by passing a hot bitumen and water mixture through a rotating disc, cone, or wheel with a stator. In this emulsification process, the hot binder separates into tiny globules, dispersing in water treated with a small quantity of emulsifying agent. The water serves as the continuous phase, while the binder globules form the discontinuous phase. Through proper selection of emulsifying agents and manufacturing controls, various types and grades of emulsified asphalts are created.
Advantages of Using Bitumen CMS
- No petroleum solvent required for liquefaction.
- Minimal or no hydrocarbon emissions.
- Usable without additional heating in most cases.
- Capability to coat damp aggregates effectively.
- Applicability with cold materials in remote areas.
- Wide range of emulsion types available.

FAQ
Frequently asked questions from buyers about Bitumen CMS:
Q1: What are the main applications of Bitumen CMS?
A1: CMS emulsion is mainly used for road mixing, patch repair, surface dressing, and spray sealing where medium curing provides balanced setting time and adhesion.
Q2: What is the minimum order quantity (MOQ)?
A2: MOQ usually starts from 20 MT in IBC tanks or drums. Bulk orders of 100 MT+ are more cost-efficient and preferred by overseas buyers.
Q3: What packaging options are available?
A3: Bitumen CMS is supplied in 200 kg drums, 1 MT IBC tanks, or in bulk tankers. Packaging is SGS certified and export-ready for global shipment.
Q4: Do you provide certificates and quality assurance?
A4: Yes. Every order comes with COA, MSDS, ASTM/EN compliance. Third-party inspection (SGS, BV, GeoChem) can be arranged before shipment if requested.
Q5: What are the delivery and payment terms?
A5: Standard delivery is within 7–12 days after confirmation. Payment terms include TT (Telegraphic Transfer) and LC (Letter of Credit), negotiable for bulk buyers.
