Saint-Gobain Strip-N-Stick®
Norseal SNS 200A is a silicone sponge rubber tape with an aggressive acrylic pressure-sensitive adhesive — Saint-Gobain's general-purpose silicone gasketing tape for sealing, cushioning and vibration damping in military and electronic equipment. It meets FDA 21 CFR 177.2600 and combines silicone's resistance to weathering and compression set with an easy peel-and-stick application, delivering 30 oz/in adhesion to steel and a -20°F to 325°F service range. The orange-tan sponge conforms to uneven surfaces and recovers after compression, and the liner stays on until the tape is in position. Available in orange-tan, 3/4" (19 mm) wide x 1/16" (1.59 mm) thick x 10 yd (9.1 m) rolls with a release liner.
Sold as a 5-roll pack for $394.75 ($78.95 per roll). Other widths are available slit to order.
Key Features of Norseal SNS 200A Silicone Sponge Tape
- Silicone sponge backing — 29 lb/ft³ R10470M silicone sponge that stays flexible and resists weathering, aging and compression set where organic rubbers harden or crack
- 30 oz/in acrylic adhesive — aggressive acrylic PSA (ASTM D1000) that grips quickly and holds on metals, plastics and painted surfaces
- -20°F to 325°F service range — handles hot enclosures, clamped hot parts and cold outdoor exposure
- Soft, recoverable gasket — 10 psi compression deflection at 25% and 25% compression set (ASTM D1056) for a low-force seal that springs back
- FDA 21 CFR 177.2600 — the silicone rubber meets FDA requirements for rubber articles intended for repeated use
What Is Norseal SNS 200A Used For?
- Environmental gasketing on military and electronic enclosures
- Seals and cushioning pads in drones, GPS units and handheld radios
- Vibration dampening and noise reduction between panels and components
- Thermal insulation and clamping pads for hot parts
- Isolation layer to reduce electrolysis between dissimilar metals
- General industrial cushioning and gap sealing

Frequently Asked Questions
What is Norseal SNS 200A used for?
SNS 200A is a silicone sponge tape with an acrylic adhesive used for gasketing, cushioning, vibration damping, noise reduction and thermal insulation. Saint-Gobain lists military equipment, drones, GPS units, walkie-talkies and environmental gasketing as typical applications.
What does the "200A" in Norseal SNS 200A mean?
In the SNS line, 200A is the silicone sponge grade with an acrylic adhesive. The "S" grades such as 100S and 440S use a silicone adhesive. SNS 300AR is the reinforced sponge version.
Should I use SNS 200A or SNS 100S?
Use 200A for stronger adhesion (30 oz/in) and a longer 24-month adhesive shelf life within -20°F to 325°F. Use 100S when the part sees -100°F to 500°F, since its silicone adhesive handles the wider range.
What temperature range is Norseal SNS 200A rated for?
-20°F to 325°F (-29°C to 163°C), per the Saint-Gobain data sheet.
Is Norseal SNS 200A flame retardant or aircraft approved?
No. SNS 200A has no flame-retardant or FAA rating. Norseal's 512AF, 515GF and 520AF foam grades are the flame-resistant options.
Is Norseal SNS 200A FDA compliant?
Yes. Saint-Gobain states SNS 200A meets FDA 21 CFR 177.2600.
What is the shelf life of Norseal SNS 200A?
24 months for the acrylic adhesive when stored at 70–90°F and under 50% relative humidity. Storing it at 40–50°F maximizes shelf life.
How do I apply Norseal SNS 200A?
Clean the surface with isopropyl alcohol so it is free of oil, grease, moisture and dust. Position the tape before removing the liner, and avoid touching the adhesive.
Does SNS 200A come with a Certificate of Compliance?
Yes. Saint-Gobain tests each lot and issues a Certificate of Compliance with test results, and we include it with every order.
What sizes does SNS 200A come in?
We supply3/4" wide x 1/16" thick x 10-yard rolls (P/N SNS200A), with a minimum order of 5 rolls. Other widths from 1/2" up and thicknesses from 1/32" to 1/2" are available slit to order; contact us for a quote.
