Manipulation Of Heatcure Acrylic Resin Write about manipulation of heat-cure resin in detail. Answer: Manipulation of Heat-cure Resin: Mix the correct proportion of polymer and monomer, i.e. polymer/monomer ratio is 3 to 3.5/1 by volume or 2.5/1 by weight. First, the liquid monomer is poured in a thick, clean glass jar and then the powder is added slowly to it. … [Read more...] about Heat-Cure Acrylic Resin Processing: From Mixing to Final Stages
