Trilene® Liquid EPDM

Trilene® Liquid EPDM represents a class of specialty lower molecular weight EPDM polymers that are available in liquid or free-flow powder form.  Trilene® Liquid EPDM is used in gear oils and greases, caulks, adhesives, roof coatings and many other applications that require a low molecular weight liquid EPDM product having the characteristics of conventional EPDM. Trilene FreeFlow® EPDM products are free-flowing polymers made by combining Trilene® Liquid EPDM and silica.

The performance of traditional EPDM now in liquid form for coatings application

Lion Elastomers has pioneered the use of EPDM in new applications leading to the introduction of Trilene® Liquid EPDM polymers to the coatings industry.



Trilene® 65, a low molecular weight EPDM terpolymer, provides coatings formulators with strong adhesion to a variety of substrates, excellent durability under the harshest environmental conditions and superior impact resistance and flexibility at low temperatures. Trilene® 65 can be formulated into high solids, VOC compliant coatings that have performance of traditional EPDM materials.


• Exceptional resistance to ozone, UV, water and chemical degradation
• Extremely low moisture permeability
• Strong adhesion to most substrates
• Hydrophobic with low surface energy
• Heat, UV and chemical cross-linking options
• Superior toughness, and impact resistance, even at low temperatures
• Supports high filler and plasticizer loading
• Extremely flexible and abrasion resistant
• Unique electrical properties

The exceptional durability and toughness of traditional EPDM is now available in a low viscosity form for coatings formulators



  • Roof Coatings
  • Barrier coatings that provide air, water or chemical impermeability
  • DTM or system applications in corrosive environments
  • Electrically resistant or conductive coatings
  • Extreme environment protective coating systems
  • Marine anti-fouling applications
  • Force cure systems
