For bears, height is usually measured at the shoulder when the animal is on all fours, according to Polar Bear International. On average, polar bears on all fours are 3.5 to 5 feet (1 to 1.5 meters) tall, but when standing on its hind legs, an adult male polar bear may reach more than 10 feet (3 m). Lengthwise, they are 7.25 to 8 feet (2.2 to 2.5 m) from head to rump. Their tail adds another 3 to 5 inches (7.5 to 12.5 centimeters). An adult male polar bear weighs around 775 to 1,200 lbs. (351 to 544 kilograms). The largest polar bear recorded weighed 2,209 pounds (1,000 kg), according to Polar Bear International.
Urethane Adhesives. Single component moisture curing adhesives cure on exposure to moisture either in the substrate or atmosphere. A small quantity of carbon dioxide is released during cure that, usually, has no effect on the bonding process.
Urethane is rolled out at 350 â 500 sf per gallon, which translates to about 2 â 3ml in thickness â and there is no way to adjust that. Furthermore, urethane does not bond well to concrete, so it is not an ideal coating to apply directly to an existing concrete floor. However, urethane is an outstanding top coat and sealer for most kinds of epoxy applied over concrete floor coatings. Urethane mortars are ideal for the food and beverage industry because it provides and seamless and smooth floor coating that is moisture and heat resistant.
