High temperature resistance test
WebTypical ethyl cyanoacrylates resist up to 180 ° F (82 ° C) with special grades resisting as high as 250 ° F (120 ° C). Generally, methyl cyanoacrylates resist 195 ° F (90 ° C). Specialty allyl cyanoacrylates can resist up to 482 ° F (250 ° C). However, these require a post-cure or secondary heat cure to achieve the temperature resistance. WebWhile tensile testing is the traditional method to assess material strength at high temperature, tensile tests require specialized samples and equipment. A hardness test, …
