Prepare / Making / How to Make
General production workflow:
-
Heat the asphalt to the required melting temperature.
-
Prepare the aqueous phase with water, surfactants, stabilizers.
-
Use a colloid mill to emulsify asphalt into fine particles.
-
Adjust viscosity and stability with additives.
-
Cool and package the adhesive.
Manufacturing Process
A high-shear emulsification process producing a uniform, stable asphalt emulsion suitable for bonding applications.
Formulation
Formulations vary, but typically include:
-
Asphalt
-
Water

SUMMARY
Bitumen (asphalt) emulsion based adhesive is a water-based, eco-friendly bonding material widely used in construction, flooring, and waterproofing applications. Produced by emulsifying molten asphalt into water using surfactants, it offers strong adhesion, flexibility, and low VOC emissions. The manufacturing process involves preparing the aqueous phase, heating asphalt, high-shear emulsification, and final adjustment of viscosity and stability. Its advantages include easy application, cost-effectiveness, and suitability for porous substrates.
