There are endless silicone sealants to choose from, varying in price and quality.  Knowing which one to choose can be a complex decision.

100% RTV silicone sealant is a completely pure product where extended silicone sealant is diluted. Pure silicone will have stronger adhesion, less shrinkage lower temperature application, and stronger resistance to weathering.

100% silicone is mildew-resistant and has inhibitors to slow discoloration (non-yellowing). It is NSF certified to be safe for incidental food contact, making it ideal for use in kitchens and other food-zone areas.

100% silicone isn’t always the best choice for every project. If your project doesn’t require extreme adhesion or temperature resistance, a less expensive, extended silicone sealant may be a better choice. However, if your silicone sealant is going to be under continuous stress in regards to weight or temperature or used in a food zone, going with 100% silicone sealant is recommended.
