Both the high build (“HB”) formula and the standard TC Ceramic formula offer the same excellent insulating qualities. However, the “HB” formula is engineered to allow for a much thicker application in a single coat, making it ideal for industrial applications where multiple layers are required.

Application Thickness

  • Standard Formula:
    • Typically applied at about 15 mils (0.4mm) per coat on vertical surfaces.
  • HB Formula:
    • Designed for thicker applications, enabling each coat to be applied between 30 mils (0.8mm) and 60 mils (1.6mm).
    • It is generally recommended not to exceed 40 mils per coat due to curing limitations. At 40 mils, curing times should be no less than 36 to 48 hours between coats at an ambient temperature of 72°F (20°C) or warmer.

Curing and Environmental Considerations

  • The ideal application conditions for both formulas involve a warm ambient temperature and low humidity.
  • Temperature and Humidity Impact:
    • Lower Temperatures or Higher Humidity:
      • These conditions require thinner applications to prevent sagging.
    • Higher Temperatures or Lower Humidity:
      • In these settings, a thicker application is possible before sagging occurs.
  • For the HB formula, the added thickness necessitates careful attention to curing time. At least 24 to 48 hours should be allowed between coats, with ample heat and airflow to expedite curing. If ambient temperatures drop below 72°F (20°C), additional curing time is required.

Industrial Efficiency and Equipment Compatibility

  • Industrial Applications:
    • The HB formula is particularly beneficial in industrial settings where multiple coats are needed, as it significantly reduces labor costs—often by half or more compared to the standard formula.
  • Equipment Compatibility:
    • Both formulas can be applied using the same spraying equipment, making the transition between standard and HB applications seamless for users.

In summary, while both formulas share the same insulating properties, the HB formula’s ability to be applied in thicker layers makes it ideal for demanding industrial projects where efficiency and cost savings are key considerations.
