Application advice:
Durabond Silicone Sealant must be finished within 5 minutes, by using a spatula or puttyknife. Employing soapwater will be of great help. Care should be taken when the sealant is applied onto metal or alkaline surfaces under wet conditions during the curing time of the sealant, chemical reaction from the acetic acid might occur. In this cases it is advisableto use a neutral curing silicone sealant.
Safety and Hygiene
While curing Durabond Silicone Sealant issues acetic acid, therefore, the working area should be well ventilated.
Due to possible irritation, all contact of the product with eyes or mucous areas must be avoided. If this should occur, rinse the affected area thoroughly with plenty of water and, if need be, see a doctor. Rubber resulting after curing may be handled without risk. Primers used with Durabond Silicone Sealant contain solvents inflammable at air temperature. Do not smoke or use unprotected flame near the working area. If eyes are splashed, rinse thoroughly with plenty of water, otherwise, see a doctor. Use gloves, and in case of splashing, wash with industrial detergent when the product is still fresh.
