Sentinel Adhesive 626 and Sentinel Adhesive 747 are both high-performance adhesives used in the construction industry. While they share some similarities, there are also some differences between the two.
Here are some of the key differences between Sentinel Adhesive 626 and Sentinel Adhesive 747:
- Chemical composition: Sentinel Adhesive 626 is a solvent-based adhesive that is made with synthetic rubber and resin. Sentinel Adhesive 747, on the other hand, is a water-based adhesive that is made with acrylic polymers.
- Bonding strength: Both adhesives are designed to provide strong bonds. However, Sentinel Adhesive 747 is generally considered to be stronger than Sentinel Adhesive 626. It is particularly well-suited for bonding heavy-duty materials such as metals, plastics, and composites.
- Drying time: Sentinel Adhesive 626 dries more quickly than Sentinel Adhesive 747. This can be an advantage when working with materials that require a fast-setting adhesive.
- Odor: Because Sentinel Adhesive 626 is solvent-based, it has a strong odor that can be unpleasant to work with. Sentinel Adhesive 747, being water-based, has a much milder odor and is generally more pleasant to use.
- Environmental considerations: Sentinel Adhesive 747 is considered to be more environmentally friendly than Sentinel Adhesive 626 because it is water-based and has a lower VOC (volatile organic compound) content.
In summary, while both Sentinel Adhesive 626 and Sentinel Adhesive 747 are high-quality adhesives, they differ in chemical composition, bonding strength, drying time, odor, and environmental impact. The choice between the two will depend on the specific needs of the project and the preferences of the user.
