Q1: What is the primary function of Valirex Cu D60 in polymer processing?
A: Valirex Cu D60 is a copper-based catalyst designed to accelerate crosslinking reactions—particularly in peroxide-cured elastomers and thermosetting resins—enhancing cure efficiency, scorch safety, and final mechanical properties without compromising thermal stability.
Q2: Is Valirex Cu D60 compatible with common elastomeric systems such as EPDM, silicone, or fluorocarbon rubbers?
A: Yes, it demonstrates broad compatibility with saturated and unsaturated elastomers including EPDM, silicone, and certain fluoroelastomers, especially where enhanced peroxide decomposition control and reduced scorch risk are required during high-temperature processing.
Q3: How should Valirex Cu D60 be incorporated into a compound formulation?
A: It is typically added during the final mixing stage—after heat-sensitive ingredients—to ensure uniform dispersion. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight relative to the base polymer, with optimization recommended via small-scale cure trials.
Q4: Does Valirex Cu D60 require special handling or storage conditions?
A: As a fine, free-flowing powder, it should be stored in a cool, dry place under inert atmosphere or sealed packaging to prevent moisture uptake and oxidation. Standard industrial hygiene practices for metal-containing powders apply during handling.
