BITUMEN (ASPHALT) EMULSION BASED ADHESIVE
Bitumen (asphalt) emulsion based adhesive is a water-based bonding material prepared by dispersing asphalt in water with the help of emulsifiers. It is widely used for flooring, construction layers, waterproofing sheets, insulation boards, and road maintenance. Its main advantages are low VOC, easy application, strong adhesion, and cost-effectiveness.
What is Bitumen (Asphalt) Emulsion Based Adhesive
A cold-applied adhesive produced from asphalt emulsified in water, designed to bond porous and non-porous construction materials.
Description
The adhesive forms a flexible, waterproof, and durable film after water evaporation. It is environmentally friendlier compared to solvent-based versions.
Definition
A water-dilutable asphaltic adhesive stabilized with anionic or cationic emulsifiers, used in construction and flooring applications.
Meaning
It refers to an asphalt-water emulsion adhesive that provides bonding, sealing, and protective coating properties.
Preparation
-
Heat asphalt to fluid consistency.
-
Prepare aqueous phase with emulsifier and stabilizers.
-
Slowly add asphalt into the aqueous phase under high-shear mixing.
-
Cool and adjust viscosity.
