Sermagard Coated Fasteners

Stud Bolts, Nuts, Screws, Threaded Rod & Washers

The SermaGard® product line was developed initially for dip-spin application to fasteners. This development was undertaken to bring the core technology of aluminum ceramic basecoats to industrial and automotive markets. From the initial dip-spin basecoat material, SermaGard dip-spin coatings have expanded to include both organic polymer and inorganic ceramic topcoats to accommodate a wide range of performance needs. The dip-spin process allows for a relatively economic bulk application to fasteners and other small hardware.

SermaGard Spray Coatings

SermaGard spray coatings were introduced almost concurrently with SermaGard dip-spin coatings. This initiative was intended to complement the successful performance of SermaGard coatings on fasteners and extend the capabilities to components assembled with the coated fasteners. A full line of spray coatings was developed to address the ever-changing performance requirements within the automotive market. Eventually, the performance capabilities of the spray coatings were also recognized in other markets.

SermaGard Basecoats

SermaGard basecoats are composite coatings consisting of various binders combined with metallic, ceramic, or thermoplastic materials. The primary SermaGard sacrificial basecoat is a unique, water-based ceramic binder containing dispersed aluminum particles that is heat cured at relatively low temperatures to produce a ceramic bonding matrix. These functional basecoats are galvanically active, stable at elevated temperatures and electrically conductive, and provide superior adhesion as well as resistance to mechanical damage.
In addition to the family of SermaGard aluminum basecoats, a family of inorganic zinc basecoats has been designed for corrosion protection of various metal substrates. The inorganic zinc basecoats offer the flexibility for air-dry or low-temperature cure processes.

SermaGard Topcoats

SermaGard topcoats also are composite coatings that consist of various combinations of binders with metallic, ceramic, or thermoplastic materials. Extended atmospheric corrosion protection is provided through the use of polymeric topcoats, which are either water-based or low- VOC solvent coatings. Inorganic ceramic topcoats excel in applications where elevated temperatures are encountered. Depending upon the additive materials and/or the topcoat selected, SermaGard composite coating systems can impart various combinations of corrosion resistance, high-temperature oxidation resistance, and thermal shock resistance; wear, abrasion, and chemical resistance; lubricity; and release and sealing characteristics.

SermaLube® Lubricants

The SermaLube product line of auxiliary lubricants consists of specially formulated blends of binders, emulsified waxes, and stabilizers supplied as water-borne or solvent dispersions. These auxiliary lubricants are intended for use as post-lubrication sealers with all SermaGard coating systems, stainless steels, platings, phosphate pretreatments, or other metal substrates when additional lubricity or torque control on threaded fasteners is required.

Whatever the performance requirement may be, SermaGard coating systems can offer a solution.
