WebHigher molecular weight urethane acrylate oligomers require some amount of acrylate monomer (usually 30% minimum) for thorough cure due to restricted molecular mobility. Urethane acrylate oligomers do not require any volatile solvents to reduce viscosity. Instead acrylate monomers are used as reactive diluents. http://materean.com/glass-transition-temperature-tg-of-acrylates/

WebThis allows for maximization of shape change and limits material damage. The methacrylate SMPs offer a wide variety of Tg values from − 29 to 112 °C and rubbery modulus from 2.8 to 129.5 MPa, where their thermo-mechanical properties in relation to their failure strain has been explored ( Safranski and Gall, 2008 ). Webmaterials with high modulus and low elongation. Acrylic acrylate films were so brittle that it was impossible to measure their physical-mechanical properties. Polyether urethane acrylates had high elongation but undesirable high weight loss at 205°C. Aromatic urethane acrylate exhibited low modulus and high weight loss similar to PEUA-2. WebSensitive Adhesives. You need a low Tg material to prepare good pressure sensitive adhesives. This report deals with a wide range acrylate terminated oligomers in a standard formulation. Molecular weight, chemical structure variations are examined versus the Glass Transition of the oligomers and final peel strength. Each formulated adhesive ... オフィス-ステーション
