This method is more convenient for recovering heavier solid components than reclaiming delicate electronic circuits. Its applications are virtually endless, ranging from small but essential items such as … Apply a foam sealant remover directly to the dried foam sealant. The invention further concerns, in a process for removing polyurethane foam from a substrate by contacting said polyurethane foam with a solvent in which said polyurethane foam is at least partially soluble, the improvement comprising substituting 1,2-dialkyl imidazole for a portion of said solvent. And if so does it dissolve slowly enough so that the … KWIK KOMBI-FOAM PRO is a Polyurethane foam for construction industry is widely used. Uncured expanding foam, which is still soft and moist, can be removed with a solvent. Due to its tensile resilient nature, you will need an organic solvent such as denatured alcohol or acetone to dissolve polyurethane glue. While Applicants' invention works well at room temperature, more rapid dissolution may be obtained by heating the 1,2-dialkyl imidazole-containing formulation to a temperature of about 50 to about 100° C.
