Q: Can you spray paint polyurethane foam?
A: You are safe with all the water based painting .. the kind of stuf you paint the lounge wall with .
Q: Is memory foam made of polyurethane?
A: *For the manufacture of polyurethane polymers , two groupes of at the very least bifunctional substances was necessary as reagents ; compounds with isocyanate groupes , and compounds with active hydrogen atoms . The physical and chemicals nature , structure , and molecular sized of these compounds duringfluence the polymerisation response , as well as ease of processing and last physical properties of the completed polyurethane . In addition , additive such as catalysts , surfactants , blowing agents , crossing linkers , fire retardants , light stabilisers , and fillers 's use to control and amend the response procedures and performance particularities of the polymer . *Polyurethane foam ( including foam rubber ) is often made by adding little sums of unstable materials , so-called blowing agents , to the response mixture . These simple unstable chemicals yield significant performance peculiarities , primarily thermal insulation . In the beginning of the 1990s , due to their influence on ozone exhaustion , the Montreal Protocol has contributed to the importantly reduction used of numerous chlorine-containing blowing agents , such as trichlorofluoromethane ( CFC-11 ) . Other haloalkanes , such as the hydrochlorofluorocarbon 1,1-dichloro-1-fluoroethane ( HCFC-141b ) , to be utilized as interim substitutions till their stage out under the IPPC directive concerning greenhouse gases in 1994 and by the Volatile Organic Compounds ( VOC ) directive of the EU in 1997 . By the end of the 1990s , the u.s.ed of blowing agents such as carbon dioxide , pentane , 1,1,1,2-tetrafluoroethane ( HFC-134a ) and 1,1,1,3,3-pentafluoropropane ( HFC-245fa ) became more pervasive in North America and the EU , though chlorinated blowing agents staying in utilized in numerous the developing world .

Q: What hardware-store glue to bond Polyurethane foam or urethanes?
A: Hot glue is a rapid but interim solution . Becauses of such isolating properties of the foam the glue does n't cool down as quickly and gives you more 'work hours ' than hotglue normaly would . A thin layer of waterproof construction adhesive ( such as fluid nails ) applicable in each mating surface and enableed to go tacky before being joined is working well but takes several days following completionly cure . Of course a Polyurethane Cement will always be better . Ring a foam insulation provider they 'll got everything you requirements and the most suitableest guidance .
