Applications & Uses
- Applications
- Application Area
- Substrates
EpoxyGrip 2900 is normally applied directly to steel as recommended. Substrate should be dry and free of debris and all contaminants. A blasted profile of the substrate is recommended for optimum EpoxyGrip 2900 performance.
- Topcoats
EpoxyGrip 2900 is normally topcoated with an epoxy finish such as EpoxyGrip 2000 or a urethane finish such as UreGrip 3900 or UreGrip 3000. EpoxyGrip 2900, like other epoxies, tends to chalk and amber when exposed to sunlight in a humid environment.
- Pot Life
Four hours at 75° and less at higher temperatures.
