THREE COMPONENT AND WATER BASED POLYURETHANE ADHESIVE FOR CONCRETE
Three component and water based polyurethane adhesive for concrete is a high-strength bonding system designed for structural concrete repair, reinforcement and industrial flooring applications. The three-component structure provides superior mechanical stability, abrasion resistance and chemical durability.
This adhesive is commonly used for concrete-to-concrete bonding, ceramic installation on concrete, repairing cracks, anchoring, and high-load flooring systems.
What It Is
A water-based, environmentally friendly, three-component polyurethane adhesive system containing:
-
Component A: Polyol dispersion
-
Component B: Isocyanate prepolymer
-
Component C: Mineral fillers + performance additives
When combined, they form a tough, flexible, high-bond-strength polymer matrix suitable for various concrete applications.
Meaning & Description
This adhesive is designed to penetrate concrete pores, chemically react within the substrate, and form a durable, waterproof and flexible composite layer.
Being water-based gives it advantages such as:
-
Low VOC emissions
-
Easy cleanup
-
Safer handling
-
Improved workability
Preparation / How to Make
A simplified preparation method:
-
Premix Component A (polyol dispersion) with fillers, thickeners and defoamers.
-
Add Component C containing mineral fillers and rheology modifiers.
-
Just before application, blend A+C with Component B (isocyanate) under low-speed mixing.
-
Apply the mixture immediately to primed or clean concrete surfaces.
-
Allow curing under ambient conditions.
Manufacturing Process
-
Component A preparation: dispersion + additives
-
Component C preparation: filler blend
-
Component B supplied separately as isocyanate prepolymer
-
Packaging into 3-component system
-
Final mixing occurs on-site before use
Formula (General Concept)
-
Component A: Polyurethane polyol emulsion, adhesion promoters, dispersing agent
-
Component B: Aliphatic or aromatic isocyanate prepolymer
-
Component C: Calcium carbonate, silica, thickeners, plasticizers
