EPDM - A Synthetic Rubber Elastomer
Ethylene Propylene Diene M*
EPDM is a manufactured by reacting Ethylene and Propylene with
one of several Dienes. The rubbery properties, saturated backbone
and reactive sites of EPDM give it desirable properties in coatings
applications.
* In ASTM Nomenclature system, M designates a saturated polymer backbone. In contrast, R designates polymers
that contain unsaturated backbone, e.g. NR, SBR.

Curing of Trilene® Polymer: Peroxide Curing
Curing of EPDM relies on a free radical crosslinking chemistry. The
peroxide generates polymer free radicals either by adding to a double
bond or through the abstraction of Hydrogen atoms, often adjacent to
double
bond

Approaches to Achieve Curing at ROOM TEMP
• Choice of peroxide: A highly reactive peroxide is required,
especially considering the low MW of Trilene®. However, a fast
curing rate has to be balanced with sufficient operation time and
safety handling during manufacture and storage. A retarder might
be needed to protect peroxide before application.
• Choice of metal catalyst: In order to enhance the curing speed, a
Cobalt catalyst is needed. Due to the color of Cobalt catalyst, Zinc
catalyst is usually used in combination.
• Co-agents: Acrylate (category 1) and butadiene (category2) are also
used to enhance curing speed at room temperature. Co-agents
provides more unsaturation but may cause miscibility issues or
affect the long term aging performance.

Room Temperature Drying with Peroxide
Development of mechanical strength 2 days after drying
Immersion to water 20 minutes after coating
Decent curing speed is achieved with proper formulation. Typical
dry to touch time is 3-4 hours and coating can contact or immerse
to water as quick as 20 minutes after coating. Full strength was
developed 2 days after coating.

Curing of Trilene® Polymer: Pigment

Approaches to Achieve Curing at ROOM TEMP
• Choice of the photo initiator: The Irgacure® 819 (BAPO) was found
to be the most efficient and allows for the white coating to dry-totouch in as quick as 15-20 minutes;
• Surface cure vs. through cure: The oxygen has some inhibition
effect and surface cure is usually slower than through cure.
However, additional photo initiator (like Irgacure® 184 ) was found
unnecessary for formulation;
• Choice of pigment: A white TiO2 has been proved to work well in
combination with Irgacure® 819 (BAPO). Other inorganic pigments
do not work, especially when the coating is relatively thick;
• Co-agents: Some photo curable co-agents like Acrylate (category 1)
can be used to enhance the curing speed, but is not necessary for
the formulation;
• Catalyst: Generally not required.

Summary of Formulating a Trilene® Paint
• Components and ingredients can be adjusted to meet
various application requirements;
• Among all factors, choice of curatives and pigments are
probably the most important to achieve a reasonable curing
rate.
• The choice of fillers, co-agents, plasticizers, light stabilizers,
dispersing agents, fire retardants etc. all help to enhance
some of the properties.

* Based on an exemplary Trilene® peroxide formulation coated to 15mil DFT. QUV lamp peaks at
340nm with output of 0.89 w/m2. Color was compared to a reference sample not exposed to QUV.
Trilene® based membrane showed good stability for 4000
hours under QUV accelerated aging
