RTV Silicone Sealant 9238W 300ml

उत्पाद वर्णन

9238W RTV Silicone Sealant is a white colored one-component, room-temperature curing silicon elastomer designed for superior adhesion, insulation, and environmental resistance across a wide range of materials.

Kootai 9238 is a versatile one-part RTV (Room Temperature Vulcanizing) silicone elastomer engineered to meet industrial demands for bonding, sealing, and protection. It cures upon exposure to ambient moisture, creating a durable elastomer with exceptional adhesion to a variety of substrates including metals, ceramics, plastics, glass, and wood.

This neutral-cure formulation delivers excellent electrical insulation, thermal stability, and resistance to chemicals and weathering. 9238 is the ideal choice for applications requiring long-term performance in environments ranging from –50°C to +200°C. With excellent flame retardant and self-extinguishing properties, it also ensures safety where reliability under high temperatures is critical.

Features :

1. Excellent Adhesion : Bonds well to metals, ceramics, plastics, glass, wood, etc.
2. Neutral Cure System : Non-corrosive to substrates (releases alcohol vapors, not acetic acid).
3. High Chemical Resistance & Weatherability : Stable under harsh environmental conditions.
4. Superior Electrical Insulation Properties : Ideal for electronic and electrical applications.
5. Wide Temperature Resistance : Operates from -50°C to +200°C.
6. Self-Extinguishing : Offers flame retardant properties.
7. One-Component System : Easy to apply without mixing.
8. Room Temperature Vulcanizing (RTV) : Cures with moisture in the air at room temperature.

Industrial Applications :

1. Sealing and bonding in electronics and electrical devices
2. Waterproofing for enclosures and circuit housings
3. Dust and moisture barriers for industrial control units
4. Shock-absorbing layer for sensitive electronic modules
5. Adhesion where thermal cycling and flame resistance are crucial
6. Use in automotive, telecommunication, lighting, and power supply industries

FAQs :

Q1: What materials does 9238 adhere to?

A1: 9238 exhibits excellent bonding with aluminum, stainless steel, copper, brass, glass, ABS, PET, and PCB. Moderate adhesion with PC and lower adhesion to PE/PP.

Q2: Does it require a primer?

A2: In most cases, primer is not needed. However, surface prep with a solvent like alcohol or xylene and testing on the target substrate is recommended.

Q3: How is it applied?

A3: It is dispensed directly from the cartridge. Once exposed to air, it begins curing and becomes tack-free in under 10 minutes at room temperature and 50% RH.

Q4: What are the available packaging sizes?

A4: It comes in 50ml, 100ml, 300ml, 2600ml, and 300kg bulk containers. Custom packaging is also available on request.

Q5: How should it be stored?

A5: Store in a cool, dry place under 25°C. Keep away from direct sunlight and out of reach of children. Shelf life is 6 months.

Q6: Is it safe to use indoors?

A6: Yes, but ensure good ventilation. It releases alcohol vapors during curing, which should not be inhaled in high concentration
