What is Dowsil 737 Neutral Cure Sealant Silicone Clear used for?
Answer: Dowsil 737 Neutral Cure Sealant Silicone Clear is primarily used for sealing in construction and industrial applications. Its neutral curing process makes it ideal for sensitive substrates like metals, glass, and tiles. The sealant is perfect for joint sealing in windows, doors, and skylights, providing a waterproof barrier. For instance, when installing glass facades, using this sealant ensures durability and resistance to environmental factors. -
Question:
Is Dowsil 737 silicone sealant suitable for outdoor use?
Answer: Yes, Dowsil 737 silicone sealant is highly suitable for outdoor use. Its formulation allows it to withstand extreme weather conditions, UV radiation, and temperature fluctuations. For example, when sealing outdoor signs or structures, this sealant will offer long-lasting protection against rain and sunlight, making it an ideal choice for exterior applications. -
Question:
Can Dowsil 737 sealant be painted over?
Answer: No, Dowsil 737 Neutral Cure Sealant Silicone Clear cannot be painted over as it does not adhere to paint. The silicone's non-stick properties create a barrier that prevents paint from bonding effectively. If you need a painted surface, consider using a compatible sealant specifically designed for painting. This ensures both functionality and aesthetic appeal in your projects. -
Question:
How long does Dowsil 737 take to cure?
Answer: Dowsil 737 typically takes about 24 hours to fully cure at room temperature. Factors such as humidity and temperature can influence curing times. In practice, it’s essential to wait for complete curing before exposing the sealant to moisture or stress. This is particularly crucial in applications where a waterproof seal is necessary, ensuring reliability and preventing failure. -
Question:
Is Dowsil 737 safe for use in aquariums?
Answer: While Dowsil 737 is a strong sealant, it is not recommended for use in aquariums or any application with direct contact with drinking water. Its chemical composition may leach harmful substances into water. For aquariums, specialized aquarium-safe sealants should be used to ensure the health and safety of aquatic life. -
Question:
What surfaces can Dowsil 737 bond to?
Answer: Dowsil 737 bonds effectively to a variety of surfaces, including glass, metals, ceramics, and certain plastics.

For example, it’s commonly used to bond fixtures in kitchens and bathrooms, where durability and moisture resistance are important. -
Question:
Can Dowsil 737 be used in high-temperature environments?
Answer: Yes, Dowsil 737 is formulated to withstand high-temperature environments. It maintains its integrity in temperatures ranging from -40°C to 150°C. This makes it especially useful in applications such as automotive sealing or in industrial settings where heat exposure is common, ensuring reliable performance over time. -
Question:
How should Dowsil 737 be stored?
Answer: Dowsil 737 should be stored in a cool, dry place, away from direct sunlight and extreme temperatures. Ideally, it should be kept in its original container, tightly sealed. Proper storage ensures that the sealant maintains its effectiveness and extends its shelf life, allowing for reliable application when needed. -
Question:
Is Dowsil 737 waterproof?
Answer: Yes, Dowsil 737 is designed to be waterproof once cured. This characteristic makes it an excellent choice for applications requiring moisture resistance, such as sealing around plumbing fixtures or outdoor structures. The waterproof seal helps prevent water ingress, protecting underlying materials from damage. -
