GE Specifications

GMW15854 FOR FASTENERS

Salt Spray • 720 Hours | Coating System • SermaGard SG-902 basecoat plus optional lubricant, SL-1127

This aluminum, ceramic finish is dip/spin-applied as SG-902 in combination with SermaLube SL-1127, a dry-to-the-touch wax, for externally driven bolts or screws primarily for high-temperature engine and transmission applications. It has a coefficient of friction, µ = 0.13 +/- 0.03 per ISO 16047. Its maximum service temperature is 650º C and it can withstand thermal spikes to 750º C.

GMW15854 FOR EXHAUST AND UNDERBODY COMPONENTS

Cyclic • GMW14872, UB, All, 4s, Method 1/2, Exposure D Thermal Soak Option 4 | Coating System • SermaGard SG-902 or SG-1105 basecoat with burnish

This aluminum, ceramic basecoat can be dip/spin-applied as SG-902 or spray-applied as SG-1105 with burnish. It is typically used for exhaust hanger rods and flanges, heat shields, body cushion and engine mounts, suspension bushings and components subject to dissimilar metal corrosion. Key properties are its outstanding adhesion, conductivity and ductility and its ability to withstand corrosion in high-temperature environments. Its maximum service temperature is 650º C and it can withstand thermal spikes to 750º C.

GM6164M

Salt Spray • 400 – 1000 Hours | Coating System • SermaGard SG-902 or 1105 basecoat plus topcoat

GM6164M-400C: This aluminum, ceramic basecoat can be dip/spin-applied as SG-902 or spray-applied as SG-1105 with burnish. It is typically used for exhaust hanger rods and flanges, heat shields, body cushion and engine mounts, suspension bushings and components subject to dissimilar metal corrosion. Key properties are its outstanding adhesion, conductivity and ductility and its ability to withstand corrosion in high-temperature environments. Its maximum service temperature is 650º C and it can withstand thermal spikes to 750º C.

GM6164M-1000A/B/E: This combination of SermaGard’s basecoat plus a topcoat system provides +1000 hours of salt spray protection. This finish offers extraordinary chip resistance and is commonly used for components subjected to extremely corrosive environments.

GMW14083 FOR SPRING BAND HOSE CLAMPS

Cyclic • GMW14872, UH, All, 4s, Method 1/2, Exposure B | Coating System • Rubicon Coating’s RoBo 2264 basecoat plus RoBo 1054 (Silver) or RoBo 1055 (black) topcoat

A unique finish developed specifically for constant tension hose clamps, Rubicon Coatings’ RoBo® eliminates the potential for stress corrosion cracking due to exposure to oxidizers while meeting the ductility and adhesion requirements necessary for pre-opened, pre-positioned (POPP) hose clamp applications.
