42、 the application substrate at a rate of 50 mm/s to 100 mm/s. The nozzle should be at a distance of (10 5) mm above the substrate to avoid touching the dispensed foam. b) After a minimum curing time of 24 h, the strings are trimmed at both ends to an overall length of between 100 mm to 150 mm to form

43、 the test specimens. c) The mass of each test specimen m shall be measured in grams with an accuracy of 0,1 g. d) The measuring cylinder shall be filled to approximately 50 % of its capacity with tap water and the reference volume V0shall be recorded. e) Each test specimen shall be submerged below t
