Each of the two Climbing Adhesion Technology (CAT) compounds has a unique formula that determines the exact chemical composition and technological process. Because of this, it responds the way a climber needs. We have decided to differentiate our new CAT compounds according to the μ value of static friction they achieved during adhesion tests.
μ [m(y)o͞o] is the coefficient of static friction. It expresses the ability of rubber to adhere to the base surface. Rubber compounds typically have μ values under 1.0. The correlation between μ and rubber adhesion is a direct relationship – the bigger the μ, the better the climber sticks to the rock.
µ ≤ 0,9 standard rubber
µ = 1,1 - 1,4 high friction rubber
µ ≥ 1,5 super sticky rubber
We have developed new rubber compounds through Climbing LAB, a project based on the idea of intensive cooperation between designers and climbers. Only a true specialist in the field knows how to create the best rubber compounds based on specific requirements. And only a top performance climber knows what actually works on a rock wall.
