GM Specifications
GMW15854 FOR FASTENERS
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
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.
GMW15196 FOR BLACK EXHAUST COMPONENTS
This black ceramic barrier coating is Robotically spray applied. It can be used for highly visible, cold-end exhaust components such as decorative exhaust tailpipe tips or bezels and hot-end exhaust manifolds where operating temperatures can range from 450º C to 650º C. It is typically applied over 304SS or 409SS Ni-Mod base metals.
GMW14669 FOR BLACK EXHAUST COMPONENTS
This black ceramic barrier coating is Robotically spray applied. It can be used for highly visible, cold-end exhaust components such as decorative exhaust tailpipe tips or bezels and hot-end exhaust manifolds where operating temperatures can range from 450º C to 650º C. It is typically applied over 304SS or 409SS Ni-Mod base metals.
GM6164M
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
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.
