  • This research undertook the assessment of six types of silicone sealants prepared. Their resistance to fungi was evaluated according to ASTM G 21, LH specification(LHCS 41 40 12), and the newly instituted KS F ISO 21265 test methods. The findings showed that KS F ISO 21265 test method exhibited the superior discriminative capability in assessing fungal resistance when compared to ASTM G 21 and LH specification(LHCS 41 40 12) test methods. Additionally, it was confirmed that oxime curing sealants demonstrated higher fungal resistance than alkoxy curing sealants. Furthermore, The introduction of a condition to assess fungal resistance after 4 weeks of immersion at 50℃ in KS F ISO 21265 is expected to enable long-term fungal resistance evaluation of sealants.
