Covinax 383-19


Covinax 383-19 is a coater-ready, surfactant stabilized vinyl acrylic copolymer adhesive developed for high performance permanent pressure sensitive applications. Covinax 383-19 is the highest performing water-based PSA in our line and is often used as a durable label adhesive. Covinax 383-19 conforms to BS 5609: 1986 Section 2 - 'Marine and Laboratory Performance of Label Base Materials’ when coated on suitable face sheet. It maintains a strong bond over a wide range of temperatures and extreme conditions and is recommended where environmental ruggedness is required. It has an excellent balance of peel and shear and works very well on many surfaces, especially corrugate box, stainless steel, and most polymeric surfaces. It will resist cold flow and will die cut and convert well, giving dry edges to finished sheets and rolls.
