We'll compare it to other common sealants and discuss its ideal applications to give you the best possible information before you buy.
Key Features of DOWSIL 795 White Silicone Adhesive
- • Superior Adhesion: DOWSIL 795 is designed to bond to a wide variety of surfaces, including glass, metal, plastics, and concrete, often without the need for a primer.
- • Neutral Cure: This type of cure means it doesn't release harsh chemicals during the curing process, making it safer to use and less likely to corrode sensitive materials.
- • Excellent Weather Resistance: Formulated to withstand extreme temperatures, UV exposure, and moisture, ensuring long-term performance even in harsh environments.
- • Flexibility and Movement Capability: It can accommodate joint movement up to ±50%, preventing cracks and leaks caused by expansion and contraction.
- • Color Stability: The white color of DOWSIL 795 resists yellowing and fading over time, maintaining a clean and professional appearance.
Pros of DOWSIL 795
- • Exceptional Adhesion to Various Substrates: This minimizes the need for multiple sealants or primers, simplifying projects and saving time and money.
- • Long-Lasting Durability and Weather Resistance: Ensures a reliable seal that can withstand harsh environmental conditions, reducing the need for frequent repairs or replacements. This is critical for projects where longevity is key.
- • Neutral Cure Formula: The neutral cure eliminates harsh odors and reduces the risk of corrosion on sensitive materials like certain metals. Also, fewer harmful VOCs than some competitive sealants.
- • High Movement Capability: Accommodates joint movement, preventing cracks and leaks caused by thermal expansion and contraction.
- • Easy to Apply: The smooth consistency of DOWSIL 795 makes it easy to extrude and tool, resulting in a professional-looking finish.
Cons of DOWSIL 795
- • Relatively Higher Price Point: Compared to some other silicone sealants, DOWSIL 795 can be more expensive, which might be a concern for budget-conscious consumers. At $18.70 per tube, consider volume needs and other budget-friendly alternatives if cost is the primary driver.
- • Requires Proper Surface Preparation: While it adheres well to many surfaces, proper cleaning and preparation are crucial for optimal bond strength. Failing to do so can compromise the seal's integrity.
- • Longer Cure Time Than Some Alternatives: Compared to fast-curing sealants, DOWSIL 795 may require a longer time to fully cure, which can delay project completion. While this allows for more tooling time, it can be a disadvantage in time-sensitive applications.
Who Should Buy DOWSIL 795?
DOWSIL 795 is ideal for professionals and DIYers who require a high-performance sealant that can withstand demanding conditions. It's particularly well-suited for applications such as:
- • Glazing and Curtain Wall Systems: Its superior adhesion and weather resistance make it a reliable choice for sealing glass and metal panels in building facades. Think commercial construction and high-rise buildings.
- • Weather Sealing of Windows and Doors: Provides a durable and flexible seal that prevents air and water infiltration, improving energy efficiency and protecting against damage.
- • Expansion and Control Joints: Its high movement capability allows it to accommodate joint movement in concrete and other construction materials, preventing cracks and leaks. This is especially critical in large-scale concrete slabs.
- • Marine Applications (Above Waterline): The weather resistance and flexibility are suitable for certain above-waterline sealing needs on boats and other marine vessels.
Ultimately, DOWSIL 795 is a sealant designed for those who prioritize quality, durability, and long-term performance over initial cost. If you need a sealant that can handle extreme conditions and maintain its integrity over time, DOWSIL 795 is an excellent choice. Consider it when comparing options like GE Silicone II or OSI Quad Max. Remember that surface preparation is key for successful application.
Conclusion: Price, Performance, and Recommendation
While DOWSIL 795 comes with a higher price tag than some alternatives, its exceptional performance, durability, and versatility make it a worthwhile investment for demanding applications. Its superior adhesion, weather resistance, and movement capability ensure a long-lasting and reliable seal that can withstand the test of time. It's a sealant you can trust to get the job done right, the first time.
For projects where quality and longevity are paramount, DOWSIL 795 is a top contender. While the slightly longer cure time and need for careful surface preparation should be considered, the overall benefits outweigh these drawbacks. We highly recommend DOWSIL 795 for anyone seeking a professional-grade silicone sealant.
