Q1: What is the primary function of KOSMOS EF Metal Catalyst in polymer processing?
A: KOSMOS EF Metal Catalyst is designed to accelerate crosslinking reactions—particularly in peroxide-cured elastomers and thermosetting resins—by enhancing decomposition efficiency and promoting more uniform network formation under thermal conditions.
Q2: Is KOSMOS EF compatible with common elastomer systems such as EPDM, silicone, or fluoroelastomers?
A: Yes, it demonstrates broad compatibility with saturated and unsaturated elastomers including EPDM, silicone, and certain fluoroelastomers; however, optimal performance requires evaluation within the specific compound formulation and cure profile.
Q3: How should KOSMOS EF be incorporated into a rubber or resin compound?
A: It is typically added during the mixing stage—either at the beginning for homogeneous dispersion or post-peroxide addition depending on the desired control over initiation timing; good dispersion is essential for consistent catalytic activity.
Q4: Does KOSMOS EF affect the scorch safety or final physical properties of cured compounds?
A: When used within recommended dosage ranges, it generally improves cure efficiency without significantly compromising scorch safety; final tensile strength, elongation, and compression set are typically enhanced due to more complete crosslink development.
Q5: What storage conditions are recommended to maintain product stability?
A: Store in original sealed containers at temperatures between 5 °C and 25 °C, protected from moisture and direct sunlight; avoid prolonged exposure to elevated humidity or freezing conditions.
