  • What types of plasticizers are used in adhesives & sealants?
  • Oils (like paraffinic, naphthenic, and aromatic) are used mainly as plasticizers in non-polar adhesives. These are generally used in the hot-melt adhesives and sealants. Base polymers include the mid-blocks of styrene-butadiene copolymers and polyolefin-based adhesives. Polymeric plasticizers are used frequently in adhesives and sealants.
  • 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 reduce the viscosity of adhesives & sealants?
  • Plasticizers will reduce the melt viscosity of hot-melt adhesives and 100% solids adhesives & sealants. However, the addition of certain plasticizers to a polymeric emulsion will usually result in increased viscosity. This effect can be used to formulate a waterborne adhesive having greater coating thickness build-up.
  • Are plasticizers compatible with polymers?
  • They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear. A secondary plasticizer is one that typically cannot be used as the sole plasticizer in a plasticized polymer.
  • What is plasticizer compatibility?
  • Plasticizer compatibility is the key to plasticizer performance in adhesives and sealants. In latex systems, compatibility can be assessed by observing the viscosity increase after the addition of the plasticizer and by observing the clarity of a cast film of the plasticized adhesives.
  • How do I find the right additive for my adhesives and sealants?
  • To help formulators find the right additive for their adhesives and sealants, SpecialChem has developed the world's largest and free database of chemical ingredients.
