  • There are many elastomeric joint sealant applications in construction such as structural glazing, weatherproofing and insulating glass fabrication etc. Each sealant joints require unique durability functions to perform well through building life cycle. Elastomeric joints in bathroom and kitchen is one of areas which require durable sealing. In this application, anti fungal durability is proprietary function of sealant during building life cycle. Premature failure of anti fungus resistance of sealant is putting big stresses to general contractor as well as the inhabitants due to costly rework and poor sanitation. Accordingly, when chemists design a product, they must take into account various parameters not only formulation components also test conditions in order to have long term fungal durability. This paper reviews several biocide options with various industry standards for fungus resistance performance to suggest making new test method for construction sealant industry.

  • To be applied to a humid environment such as bathroom and kitchen, sealant should have good adhesion, tensile strength, etc., it also have the resistance to fungal contamination from the environment. It is important to select right material for sanitary sealing application in order to prevent premature discoloration and fungal activities. Especially for high humidity conditions, it is crucial to have longer mildew and fungal resistance. In this article, we intended to give guide lines for developing right sanitary sealing material and practical test method for evaluating anti-fungal performances reflecting Korean residential life style.

  • 본 연구에서는 실리콘 실란트 총 6종을 제작하여 곰팡이 저항성 시험 방법인 ASTM G 21, LH 전문 시방(LHCS 41 40 12) 시험과 신규 제정된 KS F ISO 21265 시험법에 따라 곰팡이 저항성을 평가하였다. 그 결과, KS F ISO 21265 시험법이 ASTM G 21과 LH 전문 시방(LHCS 41 40 12) 시험법에 비해 곰팡이 저항성 평가에 대한 변별성이 더 큰 것으로 판단되었으며, 알콕시 경화형 실란트에 비해 옥심 경화형 실란트의 곰팡이 저항성이 더 큼을 확인하였다. 또한, KS F ISO 21265 시험법에서는 50℃에서 4주간 침수 후 곰팡이 저항성을 평가하는 조건 도입을 통해 실란트의 장기적인 곰팡이 저항성 평가가 가능할 것으로 판단된다.
