Weight vs Volume When Mixing

Spray foam material is packaged, sold and shipped on the basis of weight. Therefore, in order to figure the volume of a product packaged in the drum, converting the weight of the product within the drum into gallons is required. To do so, the specific gravity or weight per gallon of material is required information. There is likely to be a difference between manufactures, so confirm with the product supplier to provide this info or if a scale is available, weigh the container first. Specific Gravity and per gallon weight of the liquid for some manufactures are provided on the SDS or product data sheet (formerly MSDS).

Manufactured for Roofing

The Magnificent Membrane

The manufacturing and installation of low slope- polyurethane foam membranes (LS-SPF) takes place simultaneously, resulting in an emphasis is on manufacturing and processing controls. LS-SPF systems are formed by the resulting reaction created between mixing two liquid chemical components “A” and “B” while spraying to a prescribed substrate. The two liquids are packaged in individual containers, usually 55 gallon drums. The set, containing 500 lbs of Resin-“B” component and 500 to 550 lbs. Iso-“A” – are sold by the pound. They are processed in a 1:1 mix ratio or mixed equally in parts by means of plural component airless spray. Similar to airless spray painting and coating applications, the two materials are kept separate just prior to spray applying to the prepared surface. From the drums, the two liquid components are displaced or transferred equally from their individual containers to a processing machine called a proportioning unit for its ability to place both products under relatively equal pressure (proportioned equally). The proportioning unit is equipped with individual pumps and heaters that places the components under “prescribed” relatively equal, pressure (1000-2000 psi) and heat (110 to 160 degrees f).
