SANVO
Widely-Applied Silicone Sealants
Silicone sealants retain their elasticity and stability in harsh environment. The strong adhesion of our sealants forms tight seals around objects, which makes them work for wide applications, such as windows & doors repairs, outdoor and indoor decorations.
As they serve multiple industries, our sealants are modified to adhere well to most surfaces. Specialized workshops hosting automated production boost our production process by efficiently using quality materials to produce large volumes and ensure consistent quality.

How We Bring Durable Silicone Sealants
SANVO Silicone Sealants Ensure Strong Adhesion for Various Materials
Used on the installation of glass crafts, sinks, kitchenware, and more, our sealants ensure strong adhesion for different materials. They are color-customizable, and suited for most weather condition. Customized silicone sealants possess high adhesion strength and can be optimized for rapid curing for glazing and other applications.
High Quality Silicone Sealant Supplier with Specialized Workshops
SANVO has workshops specializing in chemical formulation, assembly, and other parts of production to divide work smoothly for higher productivity. Offering one-stop purchasing services, we present custom options for tube size, formula, and other features. With an automated production line and fast packaging, we can deliver within a short lead time.
Acetic silicone sealant releases slight vinegar‑like odor during curing, features fast‑curing performance, suitable for general indoor sealing projects. Neutral silicone sealant is low‑odor, non‑corrosive to metal, mirror and coated surfaces, widely used for windows & doors, bathroom and construction glazing scenarios. MS sealant, also known as modified silane sealant, is solvent‑free and low‑odor. It supports overpainting and delivers strong adhesion across diverse building substrates, well‑suited for interior renovation and multi‑material joint sealing.
Yes. Our silicone sealant is 100% waterproof, maintains good elasticity and stability under harsh outdoor weather conditions, ideal for exterior construction, window and door sealing.
We support full‑range B2B customization, including formula adjustment, color customization, packaging & private label, can & accessory options. We offer free wholesale quotation for bulk orders.
Un‑opened SANVO RTV silicone gasket maker has a 9‑month shelf‑life when stored in cool dry conditions. Once fully cured on vehicles, service life depends on surface preparation, assembly procedure and operating conditions.
Silicone sealant achieves excellent adhesion to glass, anodized aluminum, stone, ceramic tile, and most common building substrates. Fair adhesion can be obtained on many hard plastics, while pre‑test is recommended. It is incompatible with copper, brass, uncoated metal susceptible to corrosion, oily or greasy surfaces, and surfaces releasing plasticizer. Compatibility test is highly suggested prior to formal application for special substrates, and corresponding product models are available for special‑use scenarios.
As a professional silicone sealant manufacturer, we provide free product samples. Shipping cost shall be borne by the recipient. Please feel free to contact us for sample support.
For metal bonding, neutral‑cure silicone sealants from SANVO work well on anodized aluminum, coated steel and other metal substrates. Their non‑corrosive formula prevents metal damage. Acetic silicone sealants are not advised for bare metal because of corrosion risks. Proper surface cleaning improves bonding results.
For automotive applications, polyurethane sealant SV571 is ideal for windshield and side‑window replacement, offering stable adhesion to auto glass, painted metal and aluminum.
Silicone Sealants & Construction Adhesives: High-density PE rigid cartridges in 300ml / 310ml × 24 pcs/carton, aluminum foil sausage packs in 590ml / 600ml × 20 pcs/carton, and bulk industrial drums in 200L (245kg–250kg).
For general‑purpose building silicone sealants, the continuous service temperature ranges from ‑50℃ to +150℃. Special high‑temperature‑resistant silicone grades support wider temperature limits. Actual performance varies by individual model, please feel free to contact us for further data and detailed information.
Typical mechanical properties of SANVO building‑grade silicone sealants feature high strength and high‑modulus characteristics. They generally deliver tensile adhesive strength ranging from ≥0.4 MPa to ≥0.6 MPa. These sealants maintain stable performance under extreme temperatures, from ‑50 ℃ up to +150 ℃. Hardness typically falls between 20‑60 Shore A, with approximately 80% elastic recovery.
The recommended surface temperature for applying silicone sealant is 5℃‑40℃. Do not apply onto frosted, frozen or over‑hot substrates. Curing speed will slow down under low temperature & low humidity environment. Full curing depends on joint depth and surrounding conditions.
