Super Therm® 30 year test in Kansas
Outstanding 30 year results
No change in appearance over 30 years – still bright white with no tears, cracks, flaking, lifting, separating, or loss of adhesion in coating film.
K-TECH is a manufacturing facility located in Grainfield, Western Kansas, USA.
The climate is very severe with -21°C (-5°F) in winter with snow and ice and 38°C (100°F) in summer with sand-storms and very strong solar radiation.
Super Therm® was originally applied to a factory roof of K-TECH in 1989. It was inspected at tested for durability and performance on July 10, 2019
30 years later
Minimal loss of performance
There was a drop in surface temperature of 8.3°C (47°F) with outside ambient air temperature of 32°C (90°F) after 30 years (8° above ambient). Original coating film thickness was 15 mils; current film thickness is 13 mils – loss of 2 mils over 30 years is remarkable for a water-based coating.
Super Therm® prevents thermal shock – no expansion or contraction – extends life and reduces maintenance for metal roof.
