Organic Silicon

Our organic silicone adhesives and sealants deliver long-lasting performance for construction, automotive, electronics, and industrial manufacturing. With excellent weatherability, UV resistance, flexibility, and dielectric properties, silicone chemistries offer unmatched durability in harsh and variable environments.

Key Technical Highlights:

Temperature Resistance: -50°C to 180°C (special grades up to 250°C)
Elongation Range: 150%–600% (depending on structural or sealant grade)
Hardness: Shore A 20–60
Cure Mechanism: Acetoxy, oxime, alkoxy, neutral, or addition cure

These material advantages make silicone a preferred choice where high flexibility, aging resistance, and long-term sealing are required.

Frequently Asked Questions

Silicone sealants focus on flexible sealing, offering excellent weather resistance and movement capability for gaps, joints, and façades. Silicone adhesives provide stronger bonding strength, used for components that require permanent adhesion. Both share similar chemistry but are formulated for different mechanical performance profiles.

Yes. Organic silicone exhibits outstanding UV resistance, ozone resistance, thermal stability, and long-term elasticity, making it one of the most reliable materials for façade joints, curtain walls, exterior sealing, and other demanding outdoor applications. Service life typically exceeds 15–25 years under normal conditions.

Silicone bonds well to:

Glass, ceramics, aluminum, coated metal
Many plastics (PC, ABS, PVC—primer may be required)
Concrete, stone, masonry
Wood, composites

For low-surface-energy plastics (PP, PE, PTFE), specialized primers or modified silicone systems are recommended.

Most construction-grade silicones operate at –40°C to 150°C, while high-temperature silicone formulations remain stable up to 250–300°C. Electronics-grade RTV silicones offer exceptional thermal cycling resistance for PCBs, sensors, and modules.

Generally no. Cured silicone has a low-surface-energy, non-paintable finish.
If painting is required, options include:

Masking silicone regions during construction
Using paintable MS/PU hybrid sealants in specific areas
Applying special coatings compatible with silicone

Curing depends on humidity and thickness:

Skin-over time: 5–20 minutes
Tack-free time: 20–60 minutes
Full cure: typically 24 hours for thin beads (2–3 mm)
Thicker sections or deep joints may require 48–72 hours or longer. Electronic RTV silicones may have adjustable cure rates based on catalyst systems.

Electronics-grade silicone is designed to be non-corrosive, neutral-cure, and low volatile, making it suitable for:

Conformal coating
Sensors and optical components
LED packaging
Automotive ECU modules
Battery and energy-storage assemblies

Special low-molecular-weight–controlled (Low-VOC, Low-Fogging) grades prevent contamination of lenses, contacts, and precision modules.

Store in a cool, dry environment at ≤25°C, avoiding direct sunlight.
Typical shelf life:

12 months for most acetoxy and neutral-cure construction silicones
6–9 months for some high-performance modified formulations
Always keep the container tightly sealed to avoid premature moisture exposure.
