Description

Asphaltum CAS NO 8052-42-4 is a naturally occurring, complex mixture of hydrocarbons and heterocyclic compounds, primarily derived from petroleum or natural deposits. This versatile material is valued for its excellent waterproofing, adhesive, and protective properties, making it a critical component in numerous industrial applications. It is essential for manufacturers and formulators in the construction, coatings, and specialty chemical industries seeking durable, weather-resistant, and binding solutions.

Application

• Road Construction and Paving: As the primary binder in asphalt concrete for roads, highways, and airport runways.
• Roofing and Waterproofing: Used in built-up roofing (BUR) systems, shingles, and waterproofing membranes for buildings and foundations.
• Protective Coatings and Paints: Serves as a key ingredient in anti-corrosive paints, pipeline coatings, and industrial sealants.
• Adhesives and Mastics: Provides strong bonding properties in tile adhesives, underbody coatings for automobiles, and industrial mastics.
• Sound Dampening and Vibration Control: Applied in automotive and construction sectors for bituminous sheets and pads.
• Battery Manufacturing: Used as a sealant and plate expander material in lead-acid batteries.

Quality Control

Our Asphaltum is produced and tested to meet stringent industry specifications for consistency and performance. Quality is assured through comprehensive testing of key parameters such as penetration, softening point, viscosity, and ductility. Certificates of Analysis (COA) detailing batch-specific results are available upon request to ensure compliance with your project requirements and relevant standards (e.g., ASTM, AASHTO).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from sources of heat and ignition. Maintain at ambient temperatures to prevent solidification or excessive softening. Keep away from strong oxidizing agents.
