Redisil silicone sealants provide flexible and durable sealing solutions for selected industrial machinery applications, helping protect joints, housings, enclosures and equipment interfaces from moisture, dust and environmental exposure.
From machine housings and equipment enclosures to HVAC systems, electrical panels and outdoor machinery, Redisil delivers silicone sealing solutions designed around real-world industrial requirements.
Reliable. Durable. Engineered for Performance.
Silicone Sealants for Industrial Machinery
Industrial equipment often combines different materials such as aluminium, steel, glass, plastics, rubber and composites. These materials can expand, contract and move differently during operation.
A rigid seal may crack or lose contact when exposed to vibration and thermal movement.
Silicone sealants provide a flexible sealing layer that can accommodate movement while helping protect the assembly from moisture, dust and environmental exposure.
Redisil offers silicone sealants for applications where dependable adhesion, flexibility and long-term environmental resistance are important.

Redisil silicone sealants can be used for suitable joints and interfaces around machine housings and enclosures to create a flexible environmental seal.
Typical Applications
- Machine covers
- Equipment housings
- Access panels
- Control cabinets
- Electrical enclosures
- Inspection covers
Recommended: Redisil NP Pro
Outdoor/weather-exposed option: Redisil 789 Pro
Electrical Control Panels & Enclosures
Industrial machines often incorporate electrical and electronic components that need protection from moisture, dust and environmental conditions.
For suitable enclosure applications, Redisil silicone sealants can help seal:
- Panel joints
- Enclosure interfaces
- Cable-entry areas
- Control boxes
- Electrical housings
- Equipment covers
The neutral-cure characteristics of Redisil NP Pro make it particularly relevant where corrosion-sensitive metals and electrical components are involved.
Note: Sealant selection for electrical assemblies should be validated against the required electrical, thermal, ingress-protection and compatibility requirements.
HVAC & Air Handling Equipment
HVAC systems depend on properly sealed joints to help reduce air leakage and protect equipment from moisture and environmental exposure.
Redisil silicone sealants can be considered for suitable:
- Duct joints
- Ventilation equipment
- HVAC housings
- Air-handling equipment
- Equipment interfaces
- Sheet-metal joints
For demanding environments, product selection should consider temperature, humidity, vibration and substrate compatibility.
Pumps, Motors & Mechanical Equipment
Industrial pumps, motors and mechanical equipment can experience continuous vibration and thermal movement.
Flexible silicone sealing can be useful for suitable static joints and interfaces where environmental sealing is required.
Potential applications
- Equipment housings
- Protective covers
- Motor enclosures
- Static joints
- Component interfaces
- Equipment panels
For applications involving continuous oil or lubricant exposure, high operating temperatures, or critical flange sealing, the sealant should be selected specifically against those conditions rather than assuming a general-purpose Redisil product is suitable.
Outdoor Industrial Equipment
Machines installed outdoors face additional challenges:
UV exposure
Rain and humidity
Temperature cycling
Dust and pollutants
Wind and vibration
Redisil 789 Pro is particularly suited to applications where weather-grade neutral-cure sealing is required. Its product specification highlights UV and weather resistance, flexibility and performance under high humidity and temperature extremes.
Industrial Machine Sealing Challenges
Vibration
Industrial equipment can experience continuous mechanical vibration.
A flexible silicone seal can accommodate movement and help maintain contact between suitable substrates.
Thermal Expansion
Machines may heat up during operation and cool down after shutdown.
Different materials expand and contract at different rates. Flexible silicone sealing can help accommodate this movement.
Moisture
Humidity, cleaning processes and outdoor exposure can introduce moisture into equipment interfaces.
Properly designed and applied silicone seals help reduce moisture ingress.
Dust & Environmental Contaminants
Machinery operating in manufacturing environments may be exposed to dust and airborne contaminants.
Sealing suitable joints and enclosures helps create a protective barrier.
Different Substrates
Industrial machines commonly combine metals, plastics, glass, rubber and composite materials.
Redisil products offer different substrate compatibility profiles, allowing product selection according to the specific application.

Flexible silicone sealants can accommodate suitable joint movement and vibration. Redisil NP Pro is specifically described as having high flexibility and elasticity for joint movement, vibration and thermal expansion.
Can Redisil silicone sealant be used for gearbox or oil-exposed applications?
Product selection should be based on the actual oil exposure, temperature and mechanical requirements. A general-purpose silicone sealant should not automatically be specified for continuous oil exposure or critical flange sealing. For such applications, a dedicated oil-tolerant industrial sealant may be more appropriate.
Can silicone sealant replace a mechanical gasket?
In selected applications, RTV silicone can be used as a formed-in-place gasket or sealing material. However, whether it can replace a mechanical gasket depends on joint design, pressure, temperature, movement, fluid exposure and equipment specifications.
Can Redisil be used for electrical machine enclosures?
Selected Redisil products can be used for suitable electrical enclosure sealing applications. NP Pro is specified for electrical enclosure sealing and is designed as a non-corrosive neutral-cure silicone.
How long does Redisil silicone sealant take to cure?
Curing depends on the product, temperature, humidity and joint depth. For example, Redisil NP Pro specifies full cure in approximately 24 hours under stated conditions, while Redisil 789 Pro specifies approximately 7–14 days depending on humidity, temperature and joint depth.
