Product Features
1. Wide temperature range
After curing, Two Component Silicone Sealant can adapt to an extremely wide temperature range, from -40℃ to 150℃. This means that whether in the cold winter or the hot summer, the sealant can maintain stable performance and will not crack or fail due to temperature changes. This feature makes it particularly suitable for use in extreme climatic conditions to ensure the long-term reliability of the sealing effect.
2. High-strength bonding performance
The A component of the sealant is white, and the B component is black, which is black after mixing. Its precise mixing ratio, with the mixing ratio of component A and component B being 190L:19L or 19L:300ml×7, ensures that the cured sealant has high-strength bonding performance. It can form a strong bond with a variety of materials (such as glass, metal, ceramics, concrete, etc.), and is suitable for various occasions that require high-strength sealing.
3. Excellent weather resistance and chemical resistance
Two Component Silicone Sealant has excellent weather resistance and can resist UV, ozone and atmospheric aging. At the same time, it also has good chemical resistance and can resist the erosion of a variety of chemicals, including acids, alkalis and solvents. This feature enables it to maintain stable performance in various harsh environments and extend its service life.
4. Compliance with international standards
The sealant complies with GB 16776-2005 standards and is compatible with international certifications such as FDA, CE and ROHS. This means that its composition and performance have been strictly tested and meet environmental protection and safety requirements, and users can use it with confidence.
5. Fast curing and easy operation
Two Component Silicone Sealant has a relatively short curing time and can form a stable sealing layer in a short time. Its operation is simple. Just mix component A and component B in proportion and apply them to the parts that need to be sealed. This fast curing and easy operation characteristics make it particularly suitable for use in projects with tight construction time.
Application scenarios
1. Building sealing
In the field of construction, Two Component Silicone Sealant is widely used for sealing between door and window frames and walls, sealing of glass curtain walls, and waterproofing of building structures. Its excellent weather resistance and temperature resistance can ensure that the building structure maintains waterproof, windproof and moisture-proof properties during long-term use, extending the service life of the building.
2. Automobile manufacturing and maintenance
In automobile manufacturing and maintenance, this sealant is used for sealing of body gaps, window edges and engine compartments. Its high-strength bonding performance and chemical resistance can effectively prevent rainwater leakage and corrosion, and protect the safety of the internal structure of the car and electronic equipment.
3. Industrial Equipment Sealing
In industrial manufacturing, Two Component Silicone Sealant is used to seal mechanical equipment, pipe interfaces and electronic equipment housings. Its chemical resistance and high-strength bonding properties ensure the normal operation of equipment in harsh environments and prevent leakage and corrosion.
4. Home and furniture manufacturing
In home and furniture manufacturing, this sealant can be used to seal cabinets, drawers, furniture joints, and glass and ceramic products. Its beautiful black appearance and excellent bonding properties ensure the beauty and durability of furniture while preventing the infiltration of dust and liquids.
5. Shipbuilding and repair
In shipbuilding and repair, Two Component Silicone Sealant is used to seal hull gaps, deck interfaces and cabin internal structures. Its excellent water resistance and weather resistance can effectively prevent seawater leakage and protect the safety and durability of ship structures.
6. Electronic equipment sealing
In electronic equipment manufacturing, this sealant is used to seal electronic equipment housings to prevent the intrusion of dust, moisture and chemicals. Its good insulation and chemical resistance ensure the normal operation of electronic equipment in various environments.
Usage Method
- The base materials and auxiliary materials selected for the project must be tested for adhesion and compatibility, and can be put into use only after passing the test.
- The design and construction of the project must strictly abide by the technical specifications stipulated by the state for relevant projects, and refer to the “GIRAFE Two Components Silicone Structural Sealant Usage Guide”.
- Air circulation should be maintained during construction and curing environments.
- The bonding surface of the substrate must be cleaned with cleaning solvents such as toluene, xylene or acetone.
- After the glue fills the joints, use a scraper to squeeze further inward to completely fill the joints with glue, and modify the glue surface before it solidifies.
Restriction of Usage
- Cannot be used on all material surfaces that will exude grease, plasticizers or other organic solvents
- Not suitable for use on frosted or dampsurfaces
- Not suitable for use on places that are continuously soaked in water or humid all year round
- Not suitable to work when the surface of the substrate is not clean or solid.
- It is not suitable for construction when the surface temperature of the material is lower than 10°C or higher than 40°C
- It should not be used at interfaces that bear structural strength on the ground or in areas subject to excessive physical damage.

Cleaning and Maintenance
1. Cleaning
Uncured Cleaning: If the sealant has not yet cured, it can be wiped clean with a special cleaner or solvent (such as acetone or alcohol). When cleaning, use a clean cloth or sponge and avoid using hard tools to avoid scratching the surface.
Post-curing Cleaning: If the sealant has already cured, cleaning will be more difficult. You can use a blade or scraper to carefully remove excess sealant, but be careful not to scratch the surface of the substrate. For stubborn stains, use a mild detergent and a soft cloth to wipe.
2.Maintenance
Pre-construction inspection: Before using Two Component Silicone Sealant, make sure the construction surface is clean, dry and free of oil. If necessary, use a cleaner or solvent for pretreatment.
Storage conditions: Unused sealants should be stored in a dry, cool and well-ventilated environment, away from direct sunlight and high temperatures. The recommended storage temperature is 5℃ to 25℃, and ensure that the packaging is well sealed to prevent components from volatilizing or getting wet.
