F.A.Q
01. What is the ThreeBond 1200 Series?
The ThreeBond 1200 Series is a range of one-component RTV silicone sealants designed for industrial sealing applications. These products cure at room temperature when exposed to atmospheric moisture, creating flexible and durable seals without the need for heat or mixing. The range includes formulations adapted to different operating environments, including automotive, electronics and industrial equipment.
02. What are RTV silicone sealants used for?
RTV (Room Temperature Vulcanizing) silicone sealants are used to seal and protect assemblies against oil, water, dust, vibration and temperature variations. Typical applications include engine flanges, gearboxes, pumps, electrical housings, battery packs and industrial machinery.
03. How do ThreeBond 1200 Series products cure?
Products in the 1200 Series are moisture-curing sealants. They begin to cure when exposed to humidity in the air, forming a flexible elastomer that adheres to a wide range of materials while maintaining excellent sealing performance.
04. What are the advantages of the ThreeBond 1200 Series?
- One-component formulation
- Room temperature curing
- Excellent oil and chemical resistance
- High flexibility after curing
- Reliable vibration resistance
- Long-term sealing performance
- Easy application without mixing
05. Can the ThreeBond 1200 Series replace conventional gaskets?
Yes. Many products within the 1200 Series are designed to act as Formed-In-Place Gaskets (FIPG), replacing traditional pre-cut gaskets. This helps simplify assembly, improve sealing reliability and reduce inventory requirements.
06. Are ThreeBond 1200 Series sealants resistant to oil and chemicals?
Many products in the range are specifically formulated to provide excellent resistance to engine oils, lubricants, coolants and other industrial fluids. The exact chemical resistance depends on the selected product, so it is recommended to consult the Technical Data Sheet for detailed performance information.
07. Where can I find technical information for each product?
Each product page includes a detailed description of its properties, applications and technical documentation. Technical Data Sheets (TDS) and Safety Data Sheets (SDS) are also available to help you choose the appropriate sealant for your project.
08. What is the difference between RTV silicone sealants and anaerobic sealants?
RTV silicone sealants cure in the presence of atmospheric moisture and remain flexible after curing, making them ideal for sealing flanges and irregular surfaces. Anaerobic sealants cure only in the absence of air between metal parts and are primarily used for threadlocking, retaining and flange sealing on rigid metallic assemblies. The choice depends on the application, materials and performance requirements.
