RTV Silicone Sealant Momentive RTV1473 Oil Resistant For Formed In Place Gasket

Momentive RTV1473 Oil-Resistant Formed-in-Place Gasket RTV Silicone Sealant

Product Properties

Product Overview

Momentive RTV1473 is a one-component, black silicone rubber sealant designed for formed-in-place gasketing applications requiring oil resistance. Its thixotropic paste consistency allows application on vertical or overhead surfaces without sagging (up to 6mm thickness). The product cures at room temperature upon exposure to atmospheric moisture, forming a resilient elastomeric gasket while releasing acetic acid vapor as a byproduct.

Enhanced Key Properties

• Cure Mechanism: Forms elastomeric gasket via acetic acid-releasing moisture cure (avoid corrosion-sensitive metals).
• ​Temperature Resilience: Retains elasticity at ​204°C long-term; withstands ​260°C short-term.
• ​Adhesion: Primerless bonding to most substrates (test required for plastics/rubber).
• ​Critical Limitation: ​Prohibited​ for gasoline contact (causes excessive swelling) and delicate electronics.
• ​Flow Control: Thixotropic paste flows only under pressure, enabling precise bead placement.

Application Scenarios

1. ​Automotive Engine Gaskets​

   • Confirmed Use: Oil pans, valve covers, and transmission housings (Source: Automotive Manufacturing Solutions).
   • Reason: Oil resistance prevents degradation from engine oils.

2. ​Industrial Equipment Sealing​

   • Example: Compressor flanges, hydraulic systems (Source: GlobalSpec Industrial Directory).
   • Advantage: High-temperature stability suits heavy machinery.

3. ​HVAC Duct Gasketing​

   • Observed in: Commercial air handling units requiring ozone resistance (TDS-aligned property).
