- Recommended Uses
G90 Low VOC Topcoat is intended for industrial applications; either new build or maintenance. G90 Low VOC Topcoat is suitable for application on all Endura primers.
Industries:
- Oilfield & Energy Services
- Well Service Vehicles
- Drilling
- Tanks
- Cranes and Construction Equipment
- Waste and Recycling Industry
- Garbage Trucks
- Trailers and Rolling Stock
- Mix Ratio
1 part by volume of component A and 1 part by volume of component B. The recommended temperature when mixed is 68-77°F (20-25°C). Other EX-2C B components are available for different ambient conditions and application requirements.
- Surface Preparation
G90 Low VOC Topcoat can be applied over all Endura primer sealers and primer surfacers without sanding during their topcoat window. The topcoat window varies with each primer. If the primer topcoat window has been surpassed, the primer should be sanded with 240 – 280 grit sandpaper to achieve inter coat adhesion. All sanding dust must be blown off prior to application of the topcoat.
- Application Method
G90 Low VOC Topcoat can be applied using most spray painting systems.
Note: Ensure that any solvent absorbent primer surfacers are properly sealed with a primer sealer prior to application of the topcoat.
Solid Colors: Apply two single wet coats allowing up to 30 minutes flash time between coats. It is recommended that a thinner first coat be applied at 1.5 - 2.0 mils wet, followed by a second wet coat of 2.0 - 3.5 mils wet.

Note: Spraying viscosity and thinning will depend on ambient conditions, spray equipment used, and the desired surface finish. To maintain VOC compliance, if required, thin with Endura Low VOC topcoat Thinners/Reducers.

- Film Build
G90 Low VOC Topcoat has a recommended film build thickness:
WFT (Unreduced) 2.5 - 4.5 mils 69 - 114 microns
DFT 1.5 - 2.5 mils 38 - 63 microns
Poor hiding colors film build may be higher.
Theoretical coverage at 1.0 mil (25 microns) Average DFT: 898 ft² per gallon at 100% transfer efficiency.
- Dry Times
20°C 30°C 40°C Dust Free 2 Hours 1 Hours 30 Minutes Full Cure 7 Days 5 - 6 Days 3 - 4 Days Note: Dry Times are subject to ambient conditions (temperature and humidity) and good airflow and film build of the topcoat. For best results surface temperature must be 86°F (30°C) or less before topcoating. Maximum re-coat window without sanding is 16 hrs at 68°F (20°C). After 16 hours G90 Low VOC Topcoat must be sanded to achieve inter-coat adhesion. Mechanical sanding with 220 – 320 grit is recommended before topcoating.
Important Note: Ensure that no more than three coats of paint are applied in a 12-hour shift. This includes primer, mid-coat, topcoats, and clear coat. If more than 3 coats have been applied wait 10-12 hours to allow for proper solvent evaporation. The use of Super Catalyst II with Endura topcoats will accelerate drying times.
- Top Coating Infomation
This Product can be top coated with the entire range of Endura topcoat products.
- Clean Up
Clean all equipment immediately after use with Endura High Strength Gun Wash, or Endura EX-2C thinner.
- Clear Coating
G90 Low VOC Topcoat can be topcoated with all Endura clear coats. If G90 is going to be clear coated the following minimum times before application of the clear coat are recommended:
- Solid Colors: 4 Hours
The minimum clear coat times are based on based on recommended film build at 68°F (20°C) and 50% RH. The use of Supercatalyst I or II in the G90 will reduce these minimum times. Maximum re-coat window without sanding is 16 hrs at 68°F (20°C). After 16 hours G90 Low VOC Topcoat must be sanded to achieve inter-coat adhesion. Mechanical sanding with 400 grit is recommended before clear coating.
