CAF 33 Black – Silicone elastomer for heat-resistant industrial applications
CAF 33 Black is a high-quality, non-flowing, single-component silicone elastomer that cures at room temperature and has been specially developed for demanding applications. The black version of this silicone offers excellent resistance to high temperatures and chemical influences and is ideal for use in the automotive industry and for industrial seals.
Special features:
- Heat resistance: CAF 33 Black can withstand temperatures of up to +250 °C continuously and even up to +300 °C for short periods. This high level of resistance allows it to be used in extreme environments and ensures long-term functionality.
- Chemical resistance: The material is resistant to oils, antifreeze agents, and numerous other aggressive substances, making it particularly suitable for applications in demanding environments.
- Strong adhesion: CAF 33 adheres excellently to metals, plastics, ceramics, and other surfaces—both with and without primer. It offers reliable hold even under thermal expansion and mechanical stress.
- Water and moisture resistance: Ideal for applications where the material is constantly exposed to damp or wet conditions.
- Excellent dielectric properties: Its outstanding insulating properties make it the ideal choice for electrical insulation in electronics and electrical appliances.
Areas of application:
- Automotive industry: CAF 33 is used to seal engines and bond sunroofs. It ensures a secure seal even under extreme conditions in the automotive sector.
- Household appliances: Ideal for bonding oven door corners and sealing washing machine tubs. CAF 33 Black offers a secure and durable solution for demanding environments in the household appliance industry.
- Aviation: For bonding and sealing in demanding applications that require maximum temperature and chemical resistance.
- General industry: Used for sealing casting molds, pumps, turbines, and compressors. CAF 33 Black provides reliable protection against liquids and ensures long-lasting seals in high-performance applications.
Processing:
CAF 33 Black is supplied as a ready-to-use material and is easy to process. It can be applied both manually and with automated application equipment. The silicone should be applied to a clean and dry surface, and assembly must take place before the material forms a skin. Stress should be avoided until the product is fully cured to ensure optimum adhesion and durability.
