Herma expands seawater-resistant adhesives range

16 December 2013


Self-adhesives technology specialist Herma has extended its portfolio of seawater-resistant self-adhesive materials, with the launch of four new products.

According to the Germany-based company, its new adhesive grades satisfy the most stringent requirements of BS 5609 Sections 2 and 3, to remain attached to a drum, container or similar, without losing legibility, after exposure to aggressive seawater for up to three months.

“Thanks to innovative Herma multi-layer technology, proven dispersion adhesives can now be used in this environment too,” the company says.

According to Herma, the grade 880 white glossy PP label film is especially well suited to applications in which hostile weather conditions and exposure to chemicals have to be endured.

Adhesives 62Xpc and 65Tpc can now endow labels made from this film with seawater-resistant properties as well.

“These adhesives offer high or extremely high (65Tpc) initial tack and final adhesion, and very high shear strength,” Herma says.

They also share “good or exceptional” resistance to light, heat and ageing. Herma’s dispersion adhesive 64Z or UV acrylate adhesive 64B can also now be used to give seawater resistance to the company’s white matt label film PO Laser (grade 801).

Among the benefits being presented by Herma to label manufacturers are the lower procurement cost of dispersion-based self-adhesive materials and the “significantly reduced risk” of the adhesive bleeding during processing.

“No matter what type of container is being labelled, we can now supply users in this segment with a self-adhesive material for practically every conceivable application,” says Herma managing director Dr Thomas Baumgärtner.
