HOW FAR THE CURED PRODUCT STRETCHES BEFORE IT TEARS, as a percentage of its own length. AN ADVERSARY AMENDMENT TAKEN WHOLE [A-4], and the one with no new-machinery excuse: it reuses the live `PercentUnits`. IT IS THE MEASURED ANSWER TO THE QUESTION THE WHOLE FOLD TURNS ON. The queue asked whether a sealant is a sibling class of an adhesive; the elastic fact set looked like a sealant's exclusive property and IS NOT - Sikaflex-255 is sold by Sika as a direct-glazing ADHESIVE and elongates 450 %, while LOCTITE 3090, sold for bonding, elongates 2.5 %. The line runs rigid-against-elastic and cuts ACROSS the duty word, so it belongs on the parent as an optional slot and mints no `Sealant` child. Published on eleven products across four houses: LOCTITE 3090 2.5 %, AA 3491 27 %, 5188 186 %, SI 5900 and SI 5910 >=400 %, EA E-20HP 8 %; Permatex Ultra Grey >120 % and 81422 >300 %; Sikaflex-255 450 %, -221 500 %, -11 FC+ ~700 % (published as `tensile strain at break`). TWO METHODS SIT BEHIND THE ONE FIGURE - ISO 37 for the elastomeric sealants and ISO 527 for the rigid adhesives - and the pool cannot say which, which is recorded rather than papered over, as is the fact that four of the eleven figures are one-sided bounds [H5-f3]. Concern measurement.
