Harmonite® can help your formulation bind, seal and adhere better

If you have a CASE (Coating, Adhesive, Sealant, Elastomer) formulation that relies on bitumen or modified bitumen as an ingredient, Harmonite can be a high-performance, economical additive different from any other. It’s enhanced adhesive, sealing and 'spreadability' properties make it ideal for so many CASE applications; Harmonite compounds are also easy to use in a variety of field application methods – roll, brush, spray, trowel, or peel and stick.

Case Study: Reduced cost for HMPSA formulation in flashing tape.

Test Results: More effective than common asphalts and high-priced bitumens

Harmonite® meets EU REACH Article 33 communications requirements.

adhesivesAdhesive applications — How does Harmonite help your formulation 'stick' better than traditional additives and binders?

Harmonite contains up to 2.5 times the resins and asphaltenes of other bitumens — these are the highly polar and high molecular weight fractions that exhibit polymeric behavior. The result: adhesive formulations with increased tack, stiffness and viscosity.

coating sealerSealant and coating applications

  • Harmonite’s natural water proofing properties and its adhesive characteristics make it ideal for brush, roll and spray applied coatings, fillers and sealers.
  • Harmonite’s performance as a binder improves durability and shortens cure time for seal coats.
  • Harmonite helps provide a better moisture/air barrier for flashing tape, rubber-based sealants and other coatings.

The asphaltene structure of Harmonite strengthens softer petroleum fractions, impacting typical surface asphalts, cut-back oils and binders by bonding to them and forming larger molecules faster. The same asphaltenes also help increase viscosity of fluids, making them harder and more resistant to deforming flow.
