Depending on the formulation (determined by the climate of the country concerned) – 50 degrees C. to above + 45 degrees C. Both OKO OFF Road and On Road grades have been used in vehicles in hot Desert conditions and in the northern Russian winter.
OKO RTG was tested in fast moving truck tyres over a 500 mile course starting at 6,000 feet above sea level and driving down to sea level. The trucks repeated the journey until 110,000 Km (68,750 miles) had been driven. Punctures suffered early during this test remained sealed throughout. The holes remained blocked by the permanent OKO seal. After 110,000 km, the product remained effective, sealing further punctures. OKO RTG remained inside the tyre in liquid form, positioned as designed, effectively coating and protecting the inner tread area of the tyres. The inclusion of a special ingredient within the formulation kept the tyres cooler than normal.
