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.
How long is it best to leave silicone sealant to dry. There are silicones that can take an hour to dry, however, if your looking for quality, then expect to wait 24 to 36-hours depending on the temperature of what the room is.If the room is cold, then the setting time would be 36-hours.ow long is it best to leave silicone sealant to dry.
