Description

Bitumen Emulsion SS-1h Technical Details
What is SS-1h:
SS-1h stands for Slow-Setting, Grade 1, Hard Residue bitumen emulsion. It’s a cationic or anionic slow-setting emulsion (varies by region/spec) used primarily for mixing with fine aggregates, tack coats, and priming.

Features:
Slow-setting: Gives long workability time, ideal for mixing with mineral fines.
Low viscosity: Easy to spray and apply in thin films.
High residual bitumen hardness (“h”): Produces a tougher binder film after breaking and curing.
Typically water-based: Safer and more environmentally friendly than cutbacks.
Common Applications:
Tack coat between asphalt layers
Fog seal
Slurry seal mixes
Prime coat on granular bases (depends on local specs)
Cold mix asphalt with fine aggregates
Soil stabilization (light applications)
Typical Specifications (varies by ASTM D977 or regional standards):
Viscosity at 25°C: 20–100 SFS (or equivalent Saybolt Furol)
Residue by distillation: ≥ 57%
Penetration of residue: Hard grade, often 40–90 dmm
Ductility of residue: ≥ 40 cm
Sieve test: ≤ 0.10%
Storage stability (24 hrs): ≤ 1%
How it behaves:
Breaks (releases water) slowly—especially useful when mixed with fines.
Forms a uniform, durable bitumen film after curing.
Should be applied on clean surfaces; moisture content affects breaking.

Technical Data Sheet (TDS) of Bitumen Emulsion SS-1h

BITUMEN EMULSION SS-1h is a Slow Setting Cationic/Anionic Emulsion and Hard Residue.

Bitumen Emulsion SS-1h is a slow-setting bituminous emulsion formulated with a stable emulsifying agent and hard-grade residual bitumen. It is primarily used for tack coats, slurry seals, fog seals, and fine-aggregate cold mixes where extended workability and strong binding properties are required.

Handling & Storage
Store between 5°C and 55°C.
Do not allow to freeze.
Mix gently before use—avoid strong agitation.
Keep containers tightly closed.
Avoid contamination with cement, acids, salts, or diesel.

Safety Information
Water-based and non-flammable.
Avoid contact with eyes and skin.
Use standard PPE: gloves, goggles, and protective clothing.
Spillages can be washed off with water before breaking; after curing, mechanical removal is required.

Additional Notes
Must be applied on clean, dust-free surfaces.
Break time depends on humidity, temperature, and substrate.
Not compatible with strongly acidic or alkaline materials.
