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.
Typically, our TruSil 100 & Hi-Temp silicone (and other silicone sealants) will cure in 24 hours. Of course, this cure time could vary depending on environmental factors â primarily the moisture in the air. Since TruSil 100 is a moisture curing silicone sealant, it relies on the moisture in the air to cure.
