Specification of Bitumen Emulsifier for Cationic Bitumen Emulsion K3
The Asphalt Emulsifier for Cationic Asphalt Emulsion K3 is a specialized chemical solution created to create stable cationic bitumen emulsions identified under the K3 classification, which refers to slow-setting emulsions ideal for applications requiring prolonged workability, such as chip seals, cool blends, and tack coats. This emulsifier is a quaternary ammonium substance, using high cationic task to make sure optimal bond between bitumen and aggregates, particularly on negatively billed mineral surfaces. Its ionic nature ensures quick splitting and treating when used, enhancing bonding toughness and toughness in road building and construction and maintenance jobs.
The emulsifier is generally provided as a fluid concentrate with a pale-yellow to amber appearance, soluble in water, and suitable with bitumen qualities ranging from 60/70 to 160/220 penetration. The suggested dose ranges 0.3% to 1.2% by weight of the overall emulsion, depending upon the preferred thickness, security, and application needs. The emulsification process calls for a pH variety of 2.0– 5.0, maintained using hydrochloric or phosphoric acid, to support the solution and stop premature breaking.
Storage space conditions mandate a great, dry atmosphere (10– 30 ° C )in sealed containers to prevent moisture absorption or chemical deterioration, with a shelf life of as much as 12 months. The emulsifier makes certain constant solution performance, including particle dimension distribution (1– 10 microns) and storage security (≤ 1% deposit after 1 day at 20 ° C). It adheres to global standards such as ASTM D2397 and EN 13808 for cationic emulsions, assuring environmental safety and security and low poisoning.
Safety and security procedures consist of utilizing PPE (gloves, goggles) throughout managing to avoid skin or eye irritation. The item is biodegradable under controlled conditions, minimizing eco-friendly impact. Its solution leaves out harmful compounds like alkylphenol ethoxylates (APEO), straightening with international governing requirements. This emulsifier enables the manufacturing of K3 solutions with remarkable cohesion, water resistance, and aging homes, making it a trusted option for high-performance road surface areas in diverse climatic problems.

5 FAQs of Bitumen Emulsifier for Cationic Bitumen Emulsion K3
What is a cationic bitumen emulsion K3 emulsifier? A cationic bitumen emulsion K3 emulsifier is a specialized surfactant used to create stable emulsions of bitumen in water. It carries a positive charge (cationic), which enhances adhesion to negatively charged surfaces like aggregates. The “K3” classification typically refers to its performance in medium-setting emulsions, balancing breaking time and cohesion for applications like chip seals, slurry seals, or cold mixes.
How does the K3 emulsifier improve emulsion stability? The K3 emulsifier reduces surface tension between bitumen and water, dispersing bitumen into tiny droplets surrounded by an emulsifier layer. This prevents coalescence and ensures stability during storage and transport. Its cationic nature also improves compatibility with aggregates, reducing premature breaking. Stability is further enhanced by optimized pH control and mechanical processes during production.
What are the primary applications of cationic bitumen emulsions made with K3? These emulsions are ideal for road maintenance and construction, including chip sealing, tack coats, and cold mix asphalt. They perform well in moderate temperatures and adhere effectively to silica-rich aggregates. K3 emulsions are also used for patching potholes, dust suppression, and waterproofing layers due to their balanced setting time and strong bonding properties.
What is the recommended dosage of K3 emulsifier? Dosage typically ranges between 0.1% to 0.5% of the total emulsion weight, depending on bitumen grade and desired emulsion properties. Higher doses improve stability but may slow breaking times. Testing under site-specific conditions (e.g., aggregate type, temperature) is advised to optimize performance while minimizing costs.
Is the K3 emulsifier environmentally safe? Yes, K3 emulsifiers are designed to meet environmental regulations. They are free from harmful solvents and have low volatile organic compound (VOC) emissions. However, proper handling and disposal practices are essential to prevent water contamination. Always follow local guidelines for storage, application, and waste management to ensure ecological compliance.
