  • Does plasticizer migration affect adhesive performance?
  • Plasticizer migration can cause other additives to migrate too. Typical examples of these additives are UV stabilisers or Anti-Oxidants. If plasticizer migration causes these additives to migrate, the overall performance of the adhesive will deteriorate. There are several occasions where plasticizer migration can have aesthetic effects.
  • What are plasticizers and how do they affect vinyl adhesives?
  • Plasticizers are chemicals that are constantly moving and some are prone to migrating to the surface of vinyl. This migration can lead to adhesive failure and cause applied vinyl adhesives to separate. Universal Chemicals & Coatings, Inc., UNICHEM, offers vinyl bonding solutions with uniBOND® L VINYL industrial adhesive to address this issue.
  • Why are plasticizers used in adhesives and sealants?
  • For example, plasticizers can be incorporated into peelable pressure-sensitive adhesive to soften the adhesive, and thus improve peelability and clean removal. Plasticizers, arguably, are asked to provide more functions in adhesives and sealants than they do in plastic articles.
  • Do plasticizers affect adhesive performance?
  • In addition to improving peel, the tack of the adhesive can be improved. However, plasticizers will reduce the holding power of the adhesive, which is an important consideration. Plasticizers will affect the performance of solution-borne acrylic adhesives in a similar manner.
  • What are the problems with plasticized adhesive?
  • They can also cause issues when painting over. Dirt pickup – Plasticized adhesives can become sticky on the surface and pick up dirt. This dirt pick-up affects the aesthetic of the adhesive. Plasticizer leaching – When plasticizers migrate out of a compound, they can bring pigment with it, causing the pigment to ‘leach’ down the substrate.
  • Why do plasticizers migrate from PVC to adhesives?
  • Plasticizers are often put into materials to make them more flexible or malleable. As an example, PVC is heavily-plasticized to increase its flexibility. So when bonding PVC with adhesives, those plasticizers can migrate from the PVC into the adhesive. Plasticizer migration is more likely to happen in certain circumstances.
