Coupon rate vs. YTM[edit] 1  If a bond's coupon rate is less than its YTM, then the bond is selling at a discount. 2  If a bond's coupon rate is more than its YTM, then the bond is selling at a premium.  If a bond's coupon rate is equal to its YTM, then the bond is selling at par.
The silicone sprung a leak so I emptied the tank half way into buckets (thank god I moved recently and had 10 Home Depot buckets around) and applied silicone aquarium sealant on the inside and outside of that area. The silicone says it take 24 hours to fully dry-does it really take that long.
Exposed silicone is a magnet for dirt and repels paint, so never fillet with silicone, and don't use it on any surface you plan to paint. Silicone sealants typically set in a few minutes and reach full cure in less than a day. For an adhesive seal of plastic components, select a silicone/polyurethane hybrid.
