CHARLOTTE, NC -- The testing of two BASF acResin® UV curable acrylic hot melt pressure sensitive adhesives (PSAs) has demonstrated that they meet the British Standard BS5609 specification for pressure-sensitive adhesive-coated labels for marine use.

"We are very pleased that our acResin® UV PSA products have passed the rigorous BS5609 requirements," said Tim Sanborn, product marketing manager for the BASF Functional Polymers adhesives business in North America. "This result provides PSA label manufacturers with an opportunity to participate in this specialty application with acResin® UV.  Due to its excellent balance of adhesive and resistance properties, this patented PSA technology can be used for a variety of specialty label and tape applications, including medical, industrial, automotive, graphics, and now direct food contact applications requiring FDA 21 CFR Section 175.125."

The BASF UV curable acrylic hot melt PSAs meeting the BS5609 standard for marine use include

  • acResin® A 204 UV + Pinova Foral® 85 (75:25) coated at 24 gms/m2 and cured with 13mJ/cm2 UV-C ; and
  • acResin® DS 3552 + Pinova Foral® 85 (75:25) coated at 24 gms/m2 and cured with 13mJ/cm2 UV-C.

The acResin® UV PSAs were tested against The British Standard BS5609 Section 2, Part 4.1 test protocol, which evaluates the performance of the adhesive coated label material prior to printing, for which the main test is 3 months of exposure at a marine half tide site, after which the label must provide a specified level of adhesion.

acResin® UV is a new generation of high performance acrylic pressure sensitive adhesive copolymers in which the adhesive properties can be varied such that different adhesive products can be manufactured using the same adhesive raw material. The amount of radiant UV energy with which the adhesive is irradiated controls the crosslinking of macromolecules in the film. The adjustable crosslinking provides the desired adhesive properties for many applications including those requiring heat resistance, water resistance, clarity and direct food contact. acResin® UV can also be coated directly on thermally sensitive substrates. The acResin® UV technology combines the advantages of acrylic copolymers with those of hot melt processing.

Free of water and solvents, these adhesives have many significant advantages over conventional adhesives in terms of processing and environmental impact. The BASF Product Stewardship group conducted an Eco-Efficiency Analysis (EEA) and a Total Cost of Ownership (TCO) assessment for the production of one square meter of pressure sensitive coated material produced with acResin® UV compared to emulsion acrylic and solvent acrylic adhesives. These analyses quantitatively show the importance of considering the total cost of getting the label product out the door rather than just the purchase price of the adhesive
