Wax-based chain lubricants promise low friction and clean drivetrains, but the performance ceiling depends heavily on what's actually in the wax. Silca's Wax Additives let you dial in the formula of your hot-melt wax setup rather than settling for whatever pre-mixed blend happens to be available. The two-part system—tungsten disulfide and molybdenum disulfide—addresses different friction scenarios, giving you control over how your wax performs under varying loads and conditions.

Tungsten disulfide (WS2) handles the high-speed, low-load friction that dominates steady-state pedaling. The particles fill microscopic surface irregularities in your chain's rollers and plates, creating a smoother interface that reduces metal-to-metal contact. Molybdenum disulfide (MoS2) picks up where tungsten leaves off, excelling under the high-pressure boundary conditions that occur during hard accelerations and climbing efforts when chain tension spikes. Used together, they cover the full spectrum of forces your drivetrain experiences during a ride.

The practical application works like this: you add the powders to your wax pot during the melting process, and they suspend throughout the liquid wax. When you dip your chain, the additives distribute into the chain's internal surfaces alongside the wax carrier. Silca recommends specific ratios depending on whether you're starting with plain paraffin or their Super Secret Chain Blend, which already contains some additives but can be boosted further for race-day applications....
