Arexons Motorsil D Red for Industrial Engine and Flange Sealing
Arexons Motorsil D Red is a one-component RTV silicone sealant used for gearbox, pump, and compressor parting planes and flange joints where a formed-in-place gasket is required. Available from Project Sales Corp for customers and applications within India.
Not every sealing application in a rotating-equipment environment requires an anaerobic compound or a specialist turbine paste. For a class of joints — engine cover plates, gearbox housing flanges, bearing end covers, and auxiliary equipment casings — what is required is a reliable RTV silicone that forms a flexible, durable in-place gasket, cures at room temperature, and holds up to the oil exposure and vibration loads of industrial service.
Arexons Motorsil D Red is that product. It is a one-component RTV (room temperature vulcanising) silicone sealant that moisture-cures at room temperature to form a flexible, permanently elastic seal on rigid flanges and parting-plane joints where a conventional cut gasket has been replaced or supplemented by a formed-in-place compound. Available from Project Sales Corp for customers and applications within India.
Key Product Data
| Parameter | Value |
|---|---|
| Type | One-component RTV silicone sealant |
| Curing | Moisture-cure at room temperature |
| Packaging | 60 g tube |
| Application suitability | Must be confirmed against operating conditions, fluid type, and temperature for each specific joint — not all flange geometries and service conditions are suitable |
| Joint type | Rigid flanges and parting planes where a formed-in-place gasket is required |
Where Arexons Motorsil D Red Is Used
Arexons Motorsil D Red is used for gearbox, pump, and compressor parting planes and flange joints during maintenance and outage work. It forms a flexible, durable seal in situ — suitable for rigid flanges where a formed-in-place gasket is the appropriate sealing method. It is not a precision turbine parting-plane compound — that application requires BIRKOSIT or the FILLING product family — but it covers the substantial range of ancillary equipment housing joints encountered in rotating-equipment maintenance.
When to Use Arexons Motorsil D Red vs BIRKOSIT or FILLING
| Criterion | Arexons Motorsil D Red | BIRKOSIT / FILLING |
|---|---|---|
| Joint type | Cover plates, housing flanges, standard equipment joints | Precision turbine and compressor parting planes, HP steam flanges |
| Curing | Moisture-cure — bonds to surfaces; allow cure before pressurising | Does not cure — permanent elasticity, immediate workload |
| Temperature | Confirm per application — not suitable for turbine steam-side temperatures | BIRKOSIT: 900°C · FILLING: 950°C |
| Surface requirement | Standard flange face — not for precision turbine Ra specifications | Ra 0.8–1.2 μm machined surface |
| OEM approval | Not applicable — confirm per equipment OEM requirements | Siemens TMI-Nr. 431/93b and GE/Alstom approved |
Practical Points
Arexons Motorsil D Red is supplied in 60 g tubes — an appropriate size for the cover plate, end cover, and ancillary housing joints that characterise its application scope. It should not be used on joints where BIRKOSIT or a FILLING product is the correct specification. Application suitability — specifically confirmation that the operating conditions, fluid, and temperature are within the product's capability — should be verified for each new joint type before first use.
