Confidential DBA Lion Elastomers 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 Lionthe Copolymer Geismar, LLC (α-H). DBA Lion Elastomers Confidential 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. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential 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. Lion Copolymer Geismar, LLC Confidential DBA Elastomers PPO:Lion t-butyl 2-ethylperoxyhexanoate PPIN: t-Butyl peroxy-3,5,5-trimethylhexanoate TBPB: t-Butyl Peroxybenzoate Curing of Trilene® Polymer: Photo / UV Curing BAPO: Bis-Acyl-Phosphine Oxide, IRGACURE® 819, Peak adsorption 371, 400 nm, CAS# 162881-26-7 Curing through photo / UV follows the same free radical crosslinking chemistry. The only difference is the source of free radicals. Irgacure® 819 (BAPO) has the best absorption and allows a curing with sunlight. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential Curing of Trilene® Polymer: Pigment Choice of pigment is the key to allow for a sunshine curing. TiO2 generally gives a window at 400nm so that Irgacure® 819 can access sufficient light energy. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential 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.

Development of curing in sunshine and shaded area. The Irgacure® 819 enables a fast curing under natural sunshine. The curing after 2 days achieves sufficient mechanical strength. Curing in shaded area is also sufficiently fast. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential Effect of Pigments in UV formulation TiO2 formulation after 600 hours of QUV Tensile strength of coatings after sunshine Color Change after QUV exposure ZnS formulation after 600 hours of QUV ZnS has much less UV absorption than TiO2, leading to higher curing and better mechanical strength, but the color stability under UV is very weak and cannot be used in formulation.

Trilene® T65 shows the best results, probably due to the more reactive and high content of DCPD.

Effect of using lower Mw Trilene® polymer as binding resin in a peroxide formulation. Lower the Mw of Trilene® could reduce the viscosity, but might induce lower mechanical strength. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential Effect of Curing Co-agents Effect of using PBD (Ricon® 156) as coagent in a peroxide formulation after 48 hours of curing. Existence of co-agents helps curing by providing extra unsaturation. However, too much co-agent could weaken the coating due to the lower Mw. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential Study of Formulation: Fillers Effect of filler type and filler load on the properties of the peroxide coatings. Both filler type and filler loading could have a deep effct on the final mechanical strength of coating. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential Effect of Plasticizers Effect of using a mineral oil as plasticizer in a starting UV formulation after 2 days of sunshine. Plasticizer can be used to reduce the paint viscosity but reduces the curing and mechanical strength. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential Effect of Light Stabilizers for UV Formulation Effect of using an HALS light stabilizer in a starting UV formulation (2 days curing). Light stabilizers could potentially compete the UV source necessary for the UV curing thus the application of light stabilizer should be carefully selected. Lion Copolymer Geismar, LLC DBA Lion Elastomers Confidential Study of Formulation: Dual Cure – Use Peroxide with Photo Initiator to Enhance Curing Addition of peroxide into a typical UV formulation. Cured in a typical summer sunshine for 7 days. The addition of peroxide into a typical UV formulation does not enhance the curing, indicating the dominance of photo initiator in formulation. However, the addition of peroxide may help the Lion Copolymer LLC area or under cloudy conditions. curingGeismar, in shade Confidential DBA Lion Elastomers 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.
