When it comes to bonding heavy surface materials like granite, quartz, or engineered stone to a substrate, the adhesive you choose can make or break the final result. A weak bond leads to delamination, costly rework, and unhappy clients. Chromalok 973 Substrate Bonder is built to eliminate all of that, giving professionals a fast, strong, and flexible bonding solution they can depend on every single time.

Surfaces and Substrates It Works With
One of the biggest advantages of Chromalok 973 is its versatility. On the surface side, it bonds effectively with engineered stone, granite, quartz, and solid surfaces.

Key Features That Make It Stand Out
Chromalok 973 is not just strong - it is smart by design. Here is what makes it a preferred choice among professionals:
- Fast Cure Speed - A working time of 4 to 7 minutes and fixture time of just 15 to 25 minutes keeps your workflow moving without unnecessary delays.
- High Shear Strength - With a shear strength of 2,200 to 2,750 PSI, the bond it creates is built to handle real-world stress and load.
- Excellent Flexibility - A tensile elongation of 60 to 80 percent means the adhesive moves with the material rather than cracking under pressure.
- Simple 1:1 Mix Ratio - Easy to measure, easy to mix, and ready to apply without complicated preparation steps.
