Customer Questions & Answers

  • Question: What is Dow Corning 999A Silicone Glazing Sealant used for?

    Answer: Dow Corning 999A Silicone Glazing Sealant is primarily used for sealing glass and glazing applications in commercial and residential buildings. Its flexible and durable nature allows it to accommodate the natural movement of the structures and resist weathering. This makes it ideal for contractors and DIY enthusiasts who require robust sealing in windows or doors, ensuring that installations are watertight and energy-efficient.
  • Question: Is Dow Corning 999A suitable for outdoor use?

    Answer: Yes, Dow Corning 999A is designed for outdoor applications due to its excellent weather resistance and UV stability. This sealant withstands harsh environmental conditions, making it perfect for use in external glazing on buildings, skylights, and other structures exposed to sunlight and moisture. This durability ensures that your glazing remains intact and effective over time.
  • Question: How does Dow Corning 999A perform in high-temperature conditions?

    Answer: Dow Corning 999A Silicone Glazing Sealant performs exceptionally well in high-temperature environments. It maintains its integrity and adhesion even when exposed to extreme heat, making it suitable for glazing applications in areas that experience substantial temperature fluctuations. This characteristic ensures that the seal remains effective, providing long-lasting protection against air and moisture infiltration.
  • Question: Can I paint over Dow Corning 999A Silicone Sealant?

    Answer: No, Dow Corning 999A Silicone Sealant is not paintable. Its silicone formulation prevents paint from adhering properly, which could lead to peeling or flaking. For projects where a painted finish is desired, it's advisable to use a different type of sealant specifically designed for painting. This knowledge helps contractors and homeowners choose the appropriate materials for their aesthetics needs.
  • Question: What surfaces can I apply Dow Corning 999A to?

    Answer: Dow Corning 999A is versatile and can be applied to various surfaces, including glass, metal, and plastic. Its strong adhesion properties ensure it performs well on both porous and non-porous substrates. This makes it particularly valuable for professionals working on mixed material constructions, providing flexibility in design and structural integrity.
  • Question: How long does Dow Corning 999A take to cure?

    Answer: Dow Corning 999A typically requires 24 hours to cure fully, although this can vary based on environmental conditions such as humidity and temperature. This curing time ensures that the sealant develops its full bond strength and weather resistance. Proper planning for this curing time is essential in construction projects to avoid delays in further work.
  • Question: Can Dow Corning 999A be used in aquariums?

    Answer: No, Dow Corning 999A is not recommended for aquariums. While it is a strong sealant for architectural applications, it is not formulated for use in submerged environments where water filtration and toxicity are critical. For aquarium applications, specialized aquarium-safe sealants should be used to ensure the safety of aquatic life.
  • Question: Is Dow Corning 999A resistant to mold and mildew?

    Answer: Yes, Dow Corning 999A has inherent properties that resist mold and mildew growth. This characteristic is crucial for applications in humid and wet environments, such as bathrooms and kitchens. Its resistance contributes to maintaining clean and healthy indoor air quality, making it an excellent choice for living spaces.
  • Question: What is the shelf life of Dow Corning 999A?

    Answer: The shelf life of Dow Corning 999A Silicone Glazing Sealant is typically around 12 months when stored in a cool, dry place. This product should be kept in its original, unopened packaging to ensure its effectiveness. Understanding this helps users manage inventory, especially in professional settings where multiple projects might occur!
  • Question: Where can I buy Dow Corning 999A Silicone Glazing Sealant - White in Namibia?
