Dowsil Pr1200 Specifically Designed To Enhance The Bonding And Adhesion Of RTV And Heat-Cure
Product Attributes
Dowsil PR-1200 is a one-part, clear primer dispersed in naphtha, specifically designed to enhance the bonding and adhesion of RTV and heat-cure silicones to a variety of substrates. It is characterized by its low non-volatile content and high peel strength, making it an effective solution for improving adhesion on metals, glass, ceramics, masonry, and certain plastics.
Product Overview
Dowsil PR-1200 is a primer that serves as an adhesion promoter for silicone elastomers, ensuring a strong bond between the silicone and various substrates. It is particularly useful in applications where reliable adhesion is critical, such as in the assembly of electronic components and other industrial applications. The primer is easy to apply and can be used on a wide range of materials, including metals, glass, ceramics, and some plastics, making it a versatile choice for many industries.
Special Product Attributes
One of the key features of Dowsil PR-1200 is its ability to enhance adhesion on a variety of surfaces, including metals, glass, ceramics, and masonry, as well as some plastics like FR-4. The primer's low non-volatile content (4.9%) ensures that it provides a thin, uniform coating without excessive buildup, which is crucial for achieving optimal adhesion. Additionally, it exhibits a high peel strength of 37 ppi (or 25.5 N/cm²) on aluminum, demonstrating its effectiveness in creating strong bonds. The primer is designed to be applied in a very light, even coat, and any excess material should be wiped off to avoid overapplication, which can lead to a white, chalky surface.
Application Scenarios
Dowsil PR-1200 is commonly used in various industrial applications where silicone adhesion is required. It is particularly suitable for use in the electronics industry, where it can be applied to circuit boards and other components to ensure a strong bond with silicone sealants and coatings. The primer is also used in construction and automotive applications, where it helps to improve the adhesion of silicone sealants to different substrates, ensuring long-lasting and durable seals. Its ability to work on a wide range of materials makes it a valuable tool in many manufacturing and assembly processes.
