For Floatation

One of our most popular plastic products is our now famous Virden polyurethane pour in place foam.

Virden Perma-Bilt urethane foam is supplied in two liquids about the viscosity of 20 weight motor oil. One resin is designated “A” and the other is “B.” These two resins must be used in equal parts.

Once a person knows how long to stir the two together and the time it requires to pour into an open void or into a hole it becomes quite simple to mix and pour any amount. The resins should be reasonably cool at mixing time. The “B” component contains freon which is the blowing agent to make the foam. This freon boils at 77 degrees F. If the container is below this temperature all is well. If the “B” is over 80 degrees it is possible that it will seem to boil over when the container is opened.

Pour equal amount of “B” and “A” into a container. Beginners should make their first mix of only a small amount of each — probably a cup of each. Nothing happens when the two components are poured together. A 1/4″ electric drill with a paint mixer are the best tools to use for stirring. Stir well for one minute and the material will become creamy. You must pour at once and pour quickly as the foaming has already begun.

The mixing is very important and the time of stirring cannot be shortened very much or you will not get the maximum expansion of rigid foam. After you have poured the mixture from the container it will be only 3 to 5 minutes until the foam is completely through expanding. Should you need to pour an additional amount on top of the foam already in the container you should allow 20 minutes before pouring again.

It is very important that the cavity or mold surface is warm. In winter it is necessary to heat the mold with a light bulb, heating element or some other type of heat. It is best if the mold is 100 degrees; better still if it is 125 degrees. This means that you get greater expansion and better and lighter foam. This will reduce the cost as you get much more foam than with a cold mold.

After realizing the importance of stirring and pouring, large amounts can be poured at one time.

Perma-Bilt Urethane Rigid Foam weighs 2 pounds per cubic foot. The cells are 95% closed which makes it the finest foam available for flotation purposes. Its insulation values are greater than any other known material. Common bead foam is styrene foam and is never a liquid. Both types of foam have the same value for flotation whereas Urethane

Foam has approximately twice the insulating value of styrene foam and therefore requires only half the thickness for insulating purposes.

Virden Perma-Bilt packages Urethane Foam in 3 kits. The No. 1 Kit is 2 quarts and will make about 20 gallons or nearly 3 cubic feet. The net weight is 4V2 pounds. The No. 2 Kit is 2 gallons and comes close to making 12 cubic feet or about 80 gallons. This is exactly the same amount as 4 of the No. 1 Kits and is normally sold at the price of 3 No. 1 Kits — a saving of 1 No. 1 Kit. The net weight is 18 pounds. The No. 3 Kit is 10 gallons (2 5-gallon cans.) This weighs 100 pounds and will produce 50 cubic feet of rigid foam. The cost is normally reduced by 50% on this size kit compared to the No. 1 Kit and the No. 2 Kit. The No. 3 Kit is commonly purchased to fill pontoons.

When estimating the amount of foam needed anyone can use the following information. A cubic foot of water weighs 62 pounds. A cubic foot of urethane foam weighs 2 pounds. It will require 60 pounds of weight to press a cubic foot of foam below the water surface.

An example: A certain marine craft weighs 1,000 pounds. If you employ 16-2/3 cubic feet of foam under the craft, the 1,000 pounds would press the foam no lower than the water surface. The craft would never sink. Should the craft only weigh 500 pounds and the same amount of foam is used, 50% of the foam would be above water.

Suppose only the No. 1 Kit was mixed and poured into the floor or walls of a small boat. The boat would then be approximately 160 pounds more buoyant and in the case of developing a leak or should the boat capsize, the craft would support 160 additional pounds. This could be passengers, high priced motors or sporting equipment. All of this for the price of the No. 1 Kit.

It is possible to fill fuel drums, aluminum belly tanks or any other type of pontoon. They can never leak even if holes were shot through or rust eats away the metal covering.

Virden Perma-Bilt Urethane Foam can solve many flotation and insulation problems as well as reduce noise and vibration.

We hope we may help with your plans.
