DOWSIL 1-2287: The High-Performance Silicone Sealant
In the world of industrial adhesives and sealants, silicone-based products are among the most versatile and reliable. They offer exceptional flexibility, durability, and resistance to extreme temperatures, weathering, and chemical exposure. Among the many silicone sealants available on the market, DOWSIL 1-2287 stands out as a top-performing and cost-effective option for various applications. This article will provide an overview of DOWSIL 1-2287, its features, benefits, and typical uses.
First, let us introduce the manufacturer and supplier of DOWSIL 1-2287, INNO Specialty Chemicals. Founded in 2003, INNO is a leading producer of silicone materials and solutions, with a focus on innovation, quality, and sustainability. Based in China, INNO operates two manufacturing plants and several R&D centers, serving customers in various industries worldwide. As a strategic partner of Dow Silicones, INNO has access to the latest technologies and formulations, enabling it to offer a wide range of silicone products tailored to specific needs.
Now, let us delve into the specifics of DOWSIL 1-2287. This product belongs to the class of vinyl-functionalized silicone cyclics, also known as VCSs, which are characterized by their high reactivity, low viscosity, and excellent crosslinking properties. VCSs are especially suitable for making high-strength, high-modulus elastomers, sealants, and coatings. DOWSIL 1-2287 is a tetra-functional VCS, meaning that each molecule contains four vinyl groups (-CH=CH2) and four methyl groups (-CH3) attached to a cyclic tetrasiloxane backbone. This molecular structure gives DOWSIL 1-2287 several advantages over other silicone sealants:
- Fast cure: DOWSIL 1-2287 can cure at room temperature or under mild heating within minutes, thanks to the vinyl-methyl hydrosilylation reaction that occurs between the vinyl groups and a curing agent such as a platinum catalyst or a peroxide.n- High strength: DOWSIL 1-2287 forms a highly crosslinked network of silicone chains that can withstand tensile, compressive, and shear forces without cracking or tearing. Its tensile strength can reach up to 3 MPa, while its elongation can exceed 100%.n- High adhesion: DOWSIL 1-2287 can bond to various substrates, such as metals, glass, ceramics, plastics, and rubbers, without the need for primers or pretreatments. Its adhesion strength can reach up to 2 MPa, depending on the surface roughness and cleanliness.n- High temperature resistance: DOWSIL 1-2287 can withstand temperatures ranging from -50°C to 200°C, making it suitable for both low-temperature and high-temperature applications. It also retains its properties after prolonged exposure to UV radiation, ozone, and moisture.
With these properties, DOWSIL 1-2287 can be used in a wide range of industries, such as automotive, aerospace, electronics, construction, and healthcare. Some typical applications of DOWSIL 1-2287 include:
- Gasketing: DOWSIL 1-2287 can seal joints and gaps between engine parts, transmission components, electrical enclosures, and HVAC systems, preventing leaks and vibration.n- Potting and encapsulation: DOWSIL 1-2287 can protect sensitive electronic devices, such as sensors, LEDs, and power modules, from mechanical stress, thermal cycling, and moisture ingress.n- Coating: DOWSIL 1-2287 can provide a clear or colored coating on metal or plastic surfaces, enhancing their durability, scratch resistance, and gloss.n- Molding: DOWSIL 1-2287 can be used as a base material for making silicone rubber parts, such as O-rings, grommets, and seals, by injection or compression molding.
In conclusion, DOWSIL 1-2287 is a high-performance silicone sealant that offers fast cure, high strength, high adhesion, and high temperature resistance. It is produced by INNO Specialty Chemicals, a reliable and innovative supplier of silicone materials. DOWSIL 1-2287 can be used in various applications, such as gasketing, potting, coating, and molding, in different industries. If you need a versatile and cost-effective silicone sealant, consider DOWSIL 1-2287 from INNO Specialty Chemicals.
