FAQ's of DOWSIL RTV 732 SILICON SEALANT:
Q: How should DOWSIL RTV 732 Silicone Sealant be applied for best results?
A: For optimal adhesion, ensure that the target surface-such as glass, metal, ceramic, or painted non-porous materials-is clean, dry, and free of dust or grease. Apply the sealant directly from the 90 ml tube or 300 ml cartridge, and spread to the required thickness. Allow it to cure at room temperature for effective sealing.
Q: What are the main benefits of using this RTV silicone sealant in construction?
A: This sealant offers flexibility, strong weather and UV resistance, and excellent waterproofing. Its electrical insulation properties make it suitable for electronics, while its industrial-grade strength delivers reliable bonds in construction, metalwork, glazing, and general assembly tasks.
Q: When should DOWSIL RTV 732 Silicone Sealant be used over other types of adhesives?
A: Choose this sealant when you need a non-sag, weather-resistant, and UV-stable product for bonding or sealing glass, metal, ceramic, or non-porous surfaces, particularly where flexibility and waterproofing are required. It is especially effective in applications exposed to outdoor conditions or frequent temperature changes.
Q: Where is this silicone sealant typically applied?
A: DOWSIL RTV 732 is suited for use in construction, electronics, industrial assemblies, and repairs involving glass panes, metal frames, ceramic surfaces, and even painted cars or appliances. Its versatility makes it apt for both interior and exterior sealing needs.
Q: What is the recommended storage condition and shelf life of the sealant?
A: Store the sealant at a temperature of 32C in a cool, dry place. Under these conditions, the product maintains its quality and effectiveness for up to 18 months from the manufacturing date.
Q: How does the curing process work for this one-component RTV sealant?
A: Once extruded onto the application surface, DOWSIL RTV 732 cures at room temperature through exposure to moisture in the air. The acetoxy cure system ensures the formation of a flexible, durable seal within hours, with full cure achieved over 24-48 hours depending on bead thickness.
