THREE COMPONENT AND WATER BASED POLYURETHANE ADHESIVE FOR STONE
What is Three Component and Water Based Polyurethane Adhesive for Stone
Three component and water based polyurethane adhesive for stone is a high-strength, environmentally friendly bonding system designed for natural stones, ceramics, decorative surfaces and heavy-duty construction materials.
Description
This adhesive provides excellent adhesion, flexibility, chemical resistance and durability in indoor–outdoor applications.
Definition
A water-based, three-component polyurethane adhesive system composed of polyol, isocyanate hardener, and mineral filler paste, offering superior structural bonding.
Overview
This adhesive is widely used in architectural construction, stone cladding, industrial assembly and repair applications requiring high mechanical performance.
Meaning
It refers to a polyurethane adhesive where the reactive components cure through a water-based system to minimize VOC emissions.
Preparation
Three separate components (A/B/C) are mixed in the specified ratios and homogenized until a uniform paste is obtained.
Prepare Three Component and Water Based Polyurethane Adhesive for Stone
Raw materials must be measured accurately, ensuring moisture control and proper dispersion.
Making Three Component and Water Based Polyurethane Adhesive for Stone
The polyol base is blended with fillers, additives and water; the isocyanate component is added just before use.
Make Water Based and Three Component Polyurethane Adhesive for Stone
The system cures through a chemical reaction between polyol and isocyanate, reinforced by functional fillers.
