MFlow 648 Epoxy Grouting System | MCT CHEMICALS | MASTER BUILDER SOLUTIONS

 

USES
MFlow 648 is ideal for a wide range of high-strength grouting and fixing applications, including but not limited to:

• Fixing of starter bars and anchor bolts
• Grouting and securing of machinery, including heavy equipment and precision machines
• Under-grouting for base plates and machine foundations, including heavy-duty machinery
• Fixing of crane rails and light rail tracks
• Bedding of structural components and precast elements
• Grouting for bridge bearings, mechanical joints, and foundation elements
• Suitable for use in tunnels, over bridges, and other infrastructure projects where durability and high impact resistance are required.

FEATURES

• High early strength: Provides fast setting and early strength development.
• Flowable consistency: Ensures easy application and good flow into tight spaces.
• Non-shrink: Maintains the grout’s integrity without shrinking over time.
• High bond strength: Excellent adhesion to steel, concrete, and other construction materials.
• Corrosion and chemical resistance: Durable in harsh environments.
• Vibration and impact resistance: Effective in applications with machinery or structures subject to constant movement or stress.
• Thermal expansion compatibility: Low coefficient of thermal expansion, reducing the risk of cracks.
• Moisture resistant: Suitable for wet and humid environments, maintaining performance in difficult conditions.
