Silicone Adhesives
Rudolph Bros. & Co. offers a broad range of silicone adhesive/sealants which are liquids or pastes that cure to a strong, durable, resilient silicone rubber at room temperature on exposure to atmospheric moisture. Our adhesive/sealants are formulated to provide excellent adhesion to many different substrates and are ideal materials for bonding, sealing, or coating applications. Besides excellent adhesion, they also have high elongation and high tear strength to absorb stresses caused by substrates with dissimilar coefficients of thermal expansion or by substrates with a wide range of mechanical motion.
All of our one part adhesive/sealants show good adhesion to almost all materials except polyolefin and polytetra-fluoroethylene resins. Adhesion can be improved by following pretreatment with suitable primers. They are available in Paste-Consistency grades as well as Pourable/Self-Leveling grades. Paste grades will flow only with external pressure; they may be applied on horizontal, vertical or overhead surfaces. They will also adhere to small objects while the cure takes place. They are designed for industrial production applications such as sealing parts, adhering components or formed-in-place gasketing. Self-leveling grades are in the form of pourable liquids which will flow out and self-level on a surface. The viscosity of these products makes them ideally suited for protective coatings, filling small surface voids or for potting where thin section filling is required.
Rudolph Bros. & Co. also supplies High Strength Adhesive/Sealants. These adhesive/sealants are specifically designed for mechanical applications where high strength is required; these products offer our customers approximately twice the mechanical bond strength of the standard grade adhesive/sealants.
For electrical/electronic applications, we offer Noncorrosive, Low Odor Adhesive/Sealants. These are used in applications where neutral cure by-products, which will not cause discoloration or corrosion of copper or other sensitive metals, are required.
High Temperature Adhesive/Sealants are also available. Designed for extremely high temperature performance, these products are specially formulated and processed to perform at temperatures to 500° F continuous operation and to 600°F for short periods, with relatively little change in physical properties.
Many of our adhesive/sealants conform to various military and commercial specifications.
