Described herein is a two-component polyurethane foam adhesive, a process for preparing the same and an article made therefrom.

Two-component polyurethane foam adhesive, a process for preparing the same and an article made therefrom

Sprayable polyurethane compositions, in the form of spray polyurethane foams or low rise adhesives, when spray applied in the area of spray application at any given time, having monomeric MDI contents in the spray application area of no more than 20 parts per billion as measured in accordance with PEL Method 47 and having a viscosity of from 100 to 3,000 cP at 25° C. according to ASTM D2196.

Polyurethane compositions with low exposure to free monomeric MDI isocyanate content during spray application

A system and method for forming a polyurethane foam includes supplying an isocyanate component from a source of isocyanate to a proportioner. A resin component from a source of resin is supplied to a metering unit and an additive having an unstable state from a source of additive is supplied to the metering unit. The resin component and the additive form a reactive mixture when combined. The system and method includes delivering the reactive mixture by the metering unit to an accumulator and storing the reactive mixture in the accumulator. The system and method further includes demanding a supply of the reactive mixture with the proportioner and supplying the reactive mixture by the accumulator to the proportioner and mixing the reactive mixture with the isocyanate component by the proportioner to form the polyurethane foam.

A polyurethane spraying system minimizes emissions of a polyisocyanate while spraying a mixture of a polyisocyanate and a resin composition onto a surface. The system includes a first reactant supply tank including the resin composition. The system also includes a second reactant supply tank including the polyisocyanate. The system further includes a non-gaseous pump that is coupled with the first and second reactant supply tanks, a mixing apparatus that is coupled with the first and second reactant supply tanks for mixing the resin composition and the polyisocyanate prior to spraying, and a particular spray nozzle that is coupled with the mixing apparatus. The polyurethane spraying system produces less than 50 parts of the polyisocyanate per one billion parts of air according to the NIOSH 5521 Impingement Method while spraying the mixture onto the surface.
