Sprayon RTV Silicone

Sprayon RTV Silicone: Industrial-Grade Sealing in an Aerosol Can

When maintenance professionals need a fast, reliable seal without the mess of a traditional caulk gun, Sprayon delivers a uniquely practical solution: RTV (Room Temperature Vulcanizing) silicone in aerosol form. The SP000 Series stands apart in the broader RTV silicone category precisely because of this delivery format — a pressurized 8 oz. aerosol can that eliminates the need for a dispensing gun and allows for quick, even application in tight spaces or hard-to-reach areas on the shop floor, under a hood, or in the field.

The SP000 Series: Color-Coded for Every Application

Sprayon organizes its RTV silicone line by color, each formulated to suit specific environments and industry conventions:

• SP010 (Clear) — A general-purpose, low-VOC formula ideal where a discreet, invisible seal is needed on glass, plastic, or finished surfaces.
• SP020 (White) — Popular in HVAC, plumbing, and sanitary environments where a clean, neutral finish is preferred.
• SP030 (Blue) — Often used in automotive and equipment assembly where blue RTV is the shop-standard color for gasket-making and sensor-safe applications.
• SP040 (Black) — The go-to choice for high-contrast or high-vibration applications, including powertrain components and exhaust flanges.
• SP050 (Red, High Temp) — Engineered for extreme-heat environments, rated for demanding thermal applications where standard silicones fall short.

Performance Specs That Matter

Across the SP000 Series, Sprayon RTV silicones are rated to perform from -80°F to 600°F, making them suitable for everything from cold-weather assembly to high-temperature engine bay sealing. The aerosol formula sets in as little as 5 minutes and reaches a full cure in approximately one hour — a significant advantage in production or repair scenarios where downtime is costly.

The sealant delivers a tensile strength of 245 psi and an exceptionally low VOC content of 0.0003 g/L, making it compatible with many workplace air-quality standards. Once cured, it forms a tough, flexible bond that resists water, dust, air leakage, chemicals, oils, and greases. The mildew-resistant formula also holds up in damp or humid environments, resisting degradation from sunlight, rain, snow, and ozone exposure over time.

Versatile Substrate Compatibility

Sprayon SP000 Series RTV silicone bonds effectively to a wide range of substrates, including metal, wood, glass, plastic, ceramic, and masonry. This makes it a versatile option for MRO (maintenance, repair, and operations) teams working across mixed-material assemblies in automotive, industrial, and facility maintenance settings. One important note: paint does not adhere well to cured silicone, so any painting should be completed before application.

A Trusted Name in Industrial Maintenance

Sprayon has been a fixture in industrial MRO environments since 1968, operating today as a brand under Sherwin-Williams.
