Application
Data
ChemLine® TDC must be mixed and applied properly to achieve all its insulative properties.
Equipment Recommendations
- Mixing equipment, 1/2 ” reversible drill with jiffy type mixing blade.
- Airless Spray System; Minimum 1.0 gallons per minute at 3000 psi (Graco Bulldog or equivalent).
- 3/8” spray hose minimum, no 1/4” line or whip.
- Reversible nozzle with tip size .028” to .031”. Fan width depends on size of surface to be sprayed. For pipe, a 431 or 528 tip is recommended.
- Graco contractors gun or equivalent, no filters, with swivel nozzle.
Application Conditions
- Safety Equipment; Enclosed Areas: Saranex coveralls, full face air-supplied mask, rubber gloves (read MSDS prior to using this product).
- Safety Equipment; Open Areas: Tyvek coveralls, OSHA approved respirator, rubber gloves (read MSDS prior
to using this product). - Use only with adequate ventilation. When applying closed area, open doors, windows, or use other means to ensure fresh air circulation. Forced air circulation with fans during application and drying is required.
| For Industrial Use Only |
Mixing Instructions
- ChemLine® TDC is supplied in kits (resin and catalyst) which contain the proper ratio of ingredients.
- Material is supplied in two containers as a unit – Always mix a complete unit in the proportions supplied.
- Mechanically agitate component A (resin) until uniform consistency is achieved.
- Add component B (catalyst) and mix thoroughly for 3 to 5 minutes with mechanical mixer. The mixture must be homogeneous smooth before use. Pot life is approximately 6 hours at 74°F (25°C). Pot life will be shorter as temperature increases.
- Application; Hot Surfaces:
Multiple coats can be applied within minutes to hot surfaces above 176°F (80°C). - Application; Cold Surfaces:
Maximum wet film thickness 60 mils. Allow 8 to 12 hours (depending on temperature) for solvent release prior to application of additional coats. After final coat, heat substrate to fully cure ChemLine® TDC. - ChemLine® TDC can be applied by brush, roller or spraying.
Clean Up Solvent
Acetone, Toluene
