Heat-resistant mastic is a mouldable form of KaowoolTM Ceramic Fibre which can be trowelled, hand moulded, or injected from a hand-held pressure gun. Drying converts refractory mastic Kaowool into a strong, hard - yet light weight - insulating material which has great thermal stability up to 1000 0С and can be used in some applications up to 1260 0С. Resistance to cracking and spalling is excellent, and the dried material has strong adhesive properties. Although air drying is possible, it is recommended that assisted drying be carried out below 100 0С. Care must be taken to ensure that the moisture can readily escape. High-temperature mastic remains stable when stored in its resealable container, and a shelf life of at least six months may be expected; however, precautions should be taken against freezing.
ceramic fibre mouldable.
