Henkel Adhesive Technologies has developed a new sealant for cans in the food industry. The sealant is particularly suitable for non-round lids on tinplate and aluminium cans.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Sealing tinplate or aluminium cans with rectangular and oval lids, known in the industry as \u201enon-round lids\u201c, is a challenge. Unlike with round lids, the product can not evenly distributed around the circumference of the lid due to centrifugal force<\/strong> will be introduced. Until now, the tried-and-tested Henkel compounds DAREX OP 2928, DAREX OP 453 and DAREX OP 53BX were available for shower head and nozzle coatings.<\/p>

Additives must be added during the process to avoid certain application problems. These problems include webbing and cloudy, elongated droplets of the compound known as \u201eangel hair\u201c. With the new development of DAREX WBC 711 Handle<\/a> Adhesive Technologies the The need for these additives has been eliminated, resulting in a highly effective conventional sealant with lower application costs.<\/strong> leads. The water-based sealant offers a cost-effective alternative for the same application and enables even higher throughput<\/strong>.<\/p>

Material costs are reduced as the user no longer has to purchase the additives previously required. In addition, downtimes for additional cleaning of the application surfaces and the entire effort involved in adding and mixing the additive are eliminated. As the sealant can be applied more cleanly, this results in Less spoilage and sealant waste<\/strong>. The improved storage stability of the product leads to an improved pot life. This leads to a Reduction in metal waste as the nozzles are less likely to clog<\/strong> and quality defects such as gaps in the seal and leaks that lead to the can end being rejected.<\/p>

The Sealing compound can be used for hot and cold filling, for double-seam sealing with or without steam injection and for subsequent pasteurisation or sterilisation.<\/strong> can be used. As DAREX WBC 711 was specially developed for conventional shower head and nozzle linings, it improves the workflow for users of older generation seals. The product has a Good resistance to hot oil and water<\/strong> and complies with European food regulations and the requirements of the Food and Drug Administration (FDA) 175.300.<\/p>
