Waterproof and Airtight
Keeping water and air out is a necessity when forming gasket and seals on engine parts, cars, and appliances. Otherwise, water leakage or other damage could occur. Silicone is impervious to water, meaning water can't get through it and will never break it down. Once cured, it also does not change or degrade—no shrinking, hardening, cracking or crumbling—so gaps and cracks, which could allow unwanted air to seep through, won't form.
Resists High Temperature, UV, Oil/Grease
The areas where gaskets are formed are oftentimes exposed to extreme temperatures or UV rays. These conditions can cause other sealants to lose flexibility and degrade, leaving gaps for air and water to pass. Silicone remains unaffected and can withstand extreme temperatures, harsh outdoor elements, and even oil/grease. It will not crack, crumble, or break down.

WHY 100 PERCENT SILICONE?
Unlike acrylic, silicone is permanently:
- Waterproof—Acrylic breaks down in water over time.
- Flexible—Acrylic becomes less flexible and can even freeze at low temperatures, making it more likely to crack.
- Shrink-proof—Acrylic shrinks as the caulk dries. This shrinking can cause cracks over time.
- Crack-proof—Acrylic hardens, cracks, and crumbles over time when exposed to extreme heat and the sun's UV rays.

| Don't Waste Time and Energy |

Not all caulk is the same. Because silicone is permanently waterproof, flexible, and shrink-/crack-proof, unlike acrylic, it won't leave gaps or cracks for air and water to seep through over time. Those leaks can lead to water damage, mold growth, and higher energy bills—all of which can translate into your lost time (when you have to do the job again), lost energy, and lost money.
