Franklin Adhesives & Polymers has announced that its highest-performing water-based PSA – Covinax 383-19 – survived underwater testing for Section 2 of the Standard BS 5609: 1986, “Printed Pressure-Sensitive, Adhesive Coated Labels for Marine Use.” This coveted certification means that label manufacturers and coaters now can use Covinax 383-19, on suitable face sheet, for labels intended for containers storing hazardous materials.
Franklin developed this vinyl acrylic copolymer for demanding environments, including inclement weather, that necessitate a durable label adhesive. It maintains a strong bond over a wide range of temperatures and extreme conditions – including extended submersion in the ocean. It has optimum balance of peel and shear for these applications and works on many surfaces, most notably, on corrugated box, stainless steel and most polymeric surfaces.
Although it performs well in tough environments, Covinax 383-19 is easy to use, the company says. It is coater-ready, resists cold flow and die cuts and converts well, giving dry edges to finished sheets and rolls.
