Petra Oil’s HFMS-1 is a high float, medium setting anionic bitumen emulsion engineered for cold mix and maintenance applications where a balance between setting time and durability is essential. The designation “HFMS” stands for High Float Medium Setting, and Grade 1 indicates a lighter, more fluid formulation ideal for use in patching and cold mix paving where extended workability is needed before setting occurs.

HFMS-1 is designed to deliver excellent adhesion and durability in hot climates and on dusty or porous aggregates. Its high float characteristics provide a tough residual film that resists cracking, peeling, and water penetration over time. This makes it ideal for maintenance treatments, base stabilization, and patch repairs where a longer working time is advantageous.

This emulsion can be applied cold, making it energy-efficient and easy to use, especially in remote or infrastructure-challenged regions. It is suitable for both manual and machine-applied operations.

Key Specifications:

• Type: Anionic Bitumen Emulsion (HFMS-1)
• Setting Time: Medium Setting
