Belt tensioner - a specialized aerosol with conditioning properties for eliminating slippage and squeaking of drive belts. The components of the composition penetrate into the belt material, increasing its coefficient of friction, restoring elasticity, and slowing wear. • Increases the coefficient of friction of belts of all types • Quickly eliminates squeaking and slippage • Increases grip, pulling power, and efficiency • Extends the service life of the belt. • Does not require dismantling or tools • Suitable for preventing premature wear and cracking
