AMSOIL SILICONE SPRAY

The nonmetal line and what sits on each side

Rubber, nylon, plastics, upholstery, vinyl, wood, cardboard, and fiberglass are all inside the range, along with other nonmetal surfaces. Metal only enters the picture where it touches something nonmetal, and that boundary is what the formula was written around rather than a footnote tacked on at the end.

That distinction matters more than it sounds. A metal-on-metal load point, a wheel bearing, or a chain drive falls outside no matter how convenient the can is sitting there, and matching the material is a starting point rather than proof that a silicone film belongs on that particular seal, slide, or pivot.

Where grease is the problem, not the fix

The dry film exists for surfaces that grease or oil may damage. That is why a rubber seal, a vinyl panel, or a fabric strap usually calls for something other than an oil, even when an oil would cut friction perfectly well for a week.

Not attracting dust is the other half of the case. Grease a pivot on a machine used outdoors and it collects grit within one ride, while a dry film keeps the part contaminant-free, which counts on a slide or a latch where a paste of dust and lubricant binds the very thing you were trying to free.

Rubber life and moisture control

Helping prevent rubber from drying and cracking deals with how exposed rubber ages rather than how it wears. Seals, grommets, and boots that live through summer heat and winter cold lose flexibility and split, and a film sitting on the surface slows that down on parts nobody thinks about until one fails.

Locking out moisture works alongside it. Water standing in a rubber-to-metal joint or wicking into fabric starts a second set of problems, and the same clear film keeps it off. Both effects come from a coating that dries fast and stays where you put it.

Leather, suede, and the color question

The nonstaining formula makes it effective for waterproofing leather boots, shoes, jackets, and suede, which takes the can past the machine and into the gear hanging in the garage. Wet boots on a cold ride are a comfort problem and a durability problem showing up at the same time.

Test leather and other sensitive surfaces on a small area first. It will not damage leather, but it may slightly alter the color or hue, so a hidden section of a boot or the inside of a jacket panel answers that question before you treat something you have to look at.

Ventilation, storage, and packaging

Vapor pressure runs 3,240 to 3,930 hPa at 20°C and roughly doubles to 7,239 to 7,928 hPa at 54°C, which is the clearest reason to keep the can below 50°C (122°F) and out of direct sun. Flash point is estimated at 104°C (219.2°F) with flammability limits of 3.9 to 16.9 percent by volume.

Contents form an extremely flammable aerosol, so get the special instructions and read the safety precautions before you handle it. Work outdoors or somewhere well ventilated, clear of heat, hot surfaces, sparks, and open flames. It irritates skin, is suspected of damaging fertility or the unborn child, can cause drowsiness or dizziness, and may be fatal if swallowed and it reaches your airways, so wash up thoroughly afterward.

Proposition 65 information applies and names hexane and benzene, while the carcinogen classification does not apply because the product contains less than 3 percent DMSO extract by IP 346. Never pierce or burn the pressurized can, send contents and container to an approved waste disposal plant, and keep it away from drains. ALSSP-EA is the 10 oz. can and ALSSP-CA the case of twelve, and distribution does not include Canada.
