Product Video
Review the product video to understand its extrusion consistency, application method, surface tooling and cured flexibility. For production or project use, test the sealant on the actual glass, ceramic, aluminum or coated substrate before placing a bulk order.
Key Features & Typical Properties
One-Component Acetoxy Cure
The product is ready to use without on-site mixing. It cures by reacting with atmospheric moisture and forms a flexible silicone rubber seal.
Fast Surface Curing
Skin forming time ≤3 hours; full cure in 24 hours (23°C, 50% RH); extrusion rate ≥80 mL/min
The sealant develops a surface skin relatively quickly under normal temperature and humidity conditions. Full curing time depends on joint depth, temperature, humidity and the amount of sealant exposed to air.
Non-Sag Application
Slump ≤3 mm in vertical joints; no deformation in horizontal applications
The paste consistency supports vertical and horizontal application without excessive slumping, helping installers form cleaner and more consistent joints
Flexible Seal After Curing
Tensile modulus ≤0.4 MPa at 23°C
Tensile modulus ≤0.6 MPa at -20°C
Once fully cured, the sealant remains flexible and can accommodate normal movement in properly designed non-structural joints.
Strong Adhesion to Glass and Ceramic
The acetoxy curing system provides reliable adhesion to properly cleaned glass, glazed ceramic and other approved non-porous surfaces.
Product Advantages
Efficient for Routine Glass Assembly
The one-component format, smooth extrusion and fast surface curing make the product suitable for repetitive glass fabrication and installation work.
Suitable for Common Non-Porous Materials
The product is primarily intended for glass, glazed ceramic, ceramic tiles, selected aluminum and other compatible non-porous surfaces.
Superior Weather Resistance:
Outstanding UV resistance, temperature stability, and aging resistance, providing a service life of over 20 years
Flexible and Water-Resistant
The cured silicone forms a flexible seal that helps prevent the passage of water, air and dust through compatible joints.
Multiple Standard Colors
Standard colors can include clear, white, black and gray, subject to current production availability.
Suitable for Bulk Distribution
The product is suitable for building material distributors, hardware wholesalers, glass processors and construction supply companies requiring regular bulk purchasing under the SEIMEDA brand.

What surface preparation is required?
Surfaces must be solid, clean, dry, and free from oil, dust, or loose materials.
What affects curing time?
Temperature and humidity are key factors.
Shelf life and storage?
12 months in unopened packaging. Store in a cool, dry place below 27°C.
General Purpose Acetoxy Silicone Sealant is a ready-to-use, one-component RTV silicone sealant. It reacts with moisture in the air and releases a characteristic vinegar-like odor during curing. After curing, it forms a flexible and water-resistant seal on compatible non-porous materials.
Compared with neutral cure silicone sealant, acetoxy silicone usually provides faster surface curing and strong adhesion to glass and ceramic. However, its acidic curing system is not suitable for some corrosion-sensitive metals, cement-based materials, natural stone and other sensitive substrates.
The product is mainly recommended for:
Actual adhesion depends on surface treatment, contamination, coatings and material formulation. Test the sealant on representative production or project substrates before use.
| Substrate | General Suitability | Recommended Action |
| Clear glass | Recommended | Clean, dry and test adhesion |
| Glazed ceramic | Recommended | Remove oil, soap and surface contamination |
| Ceramic tile | Generally suitable | Confirm surface glaze and cleaning method |
| Fiberglass | Surface-dependent | Test the specific surface finish |
| Aluminum | Grade-dependent | Carry out adhesion and corrosion testing |
| Powder-coated aluminum | Coating-dependent | Compatibility and adhesion testing required |
| Painted metal | Coating-dependent | Confirm coating stability and adhesion |
| uPVC | Formulation-dependent | Test adhesion and plasticizer migration |
| Non-oily wood | Possible after testing | Check moisture content and surface coating |
| Concrete and cement | Not recommended | Use a suitable neutral construction sealant |
| Marble and granite | Not recommended | Use a validated non-staining stone sealant |
| Copper and brass | Not recommended | Acidic curing may cause corrosion |
| Galvanized steel and iron | Not recommended | Select a compatible neutral cure sealant |
| PE, PP and PTFE | Poor adhesion | Alternative adhesive or special treatment required |
General Purpose Acetoxy Silicone Sealant is formulated with silicone polymers, reinforcing fillers, acetoxy curing agents, adhesion promoters and performance additives.
During curing, the product releases acetic acid, which produces a characteristic vinegar-like odor. Adequate ventilation should be maintained during application and curing.
| Comparison Item | GP Acetoxy Silicone | Neutral Silicone |
| Curing By-Product | Acetic acid | Neutral curing by-products |
| Odor During Curing | Noticeable vinegar-like odor | Lower or different curing odor |
| Typical Surface Cure | Usually relatively fast | Depends on the neutral cure system and formulation |
| Main Substrates | Glass, glazed ceramic and compatible non-porous materials | Glass, aluminum, coated metal and a wider range of construction substrates |
| Metal Compatibility | Not suitable for some corrosion-sensitive metals | Generally lower corrosion risk |
| Typical Market Position | Cost-effective general glazing and sealing | Window, door and broader construction sealing |
| Natural Stone | Not recommended | Requires a validated non-staining grade and testing |
Choose GP acetoxy silicone for routine glass and ceramic sealing where the substrates are compatible with acidic curing. Choose NP Neutral Silicone Sealant when sealing metals, coated construction materials or other substrates that require a non-corrosive curing system.
| Product Type | Recommended Application | Main Difference |
| GP Acetoxy Silicone | General glass, ceramic and compatible non-porous surfaces | Cost-effective acid-curing general-purpose product |
| Neutral Silicone Sealant | Windows, doors, metal and general construction joints | Non-corrosive neutral curing system |
| Sanitary Silicone | Kitchen, bathroom and mold-prone wet-area joints | Dedicated mildew-resistant performance |
| Structural Silicone Sealant | Engineered structural glazing | Designed and tested for structural bonding |
| Weatherproof Silicone Sealant | Exterior façade and curtain wall weather joints | Designed for outdoor weathering and joint movement |
| Aquarium Silicone | Fish tanks and long-term water exposure | Requires appropriate water-contact and structural suitability |
For product selection by application, visit the sealant selection guide.
Check whether the substrate is suitable for acetoxy curing. Carry out adhesion and corrosion testing on aluminum, coated metal, uPVC and other uncertain materials.
Remove dust, oil, grease, moisture, old sealant and loose coating. The joint must be clean, dry and stable before application.
Use masking tape where a clean finished edge is required. Remove the tape immediately after tooling.
Cut the nozzle according to the required bead size. Apply the sealant continuously while ensuring full contact with both sides of the joint.
Finish the sealant surface before a skin forms. Correct tooling improves substrate contact, appearance and joint profile.
Maintain adequate ventilation during curing. Protect the joint from water, contamination and excessive movement until sufficient curing has occurred.
Do not assume that the entire bead is fully cured after 24 hours. Deep or enclosed joints require more time because moisture must penetrate into the sealant.
