Clariant HYDEX G Catalyst – Frequently Asked Questions (FAQ)

Q1: What is the primary function of HYDEX G Catalyst in polymer processing?

A: HYDEX G Catalyst is a highly active, organometallic compound designed to accelerate crosslinking reactions—particularly in peroxide-cured elastomers and thermoset resins—enhancing cure efficiency, improving scorch safety, and supporting consistent network formation under industrial processing conditions.

Q2: Is HYDEX G Catalyst compatible with common elastomeric systems such as EPDM, silicone, or fluorocarbon rubbers?

A: Yes, HYDEX G Catalyst demonstrates broad compatibility with high-performance elastomers including EPDM, silicone, and fluoroelastomers. Its reactivity profile allows effective integration into both conventional and low-peroxide formulations without compromising thermal stability or final physical properties.

Q3: How should HYDEX G Catalyst be handled and stored to maintain performance?

A: HYDEX G Catalyst is moisture-sensitive and should be stored under inert atmosphere (e.g., nitrogen or argon), in tightly sealed original containers, at cool and dry conditions (typically below 25 °C). Avoid exposure to air, humidity, or direct sunlight prior to use to preserve catalytic activity and shelf life.

Q4: What is the typical dosage range for HYDEX G Catalyst in industrial formulations?

A: Dosage is formulation-dependent but generally ranges from 0.1% to 2% by weight relative to the base polymer or curative system. Optimal loading is determined through small-scale rheometry and cure profiling to balance scorch time, cure rate, and final crosslink density.

Q5: Can HYDEX G Catalyst be used in food-contact or medical-grade elastomer applications?

A: HYDEX G Catalyst is intended for industrial and technical applications. For food-contact or medical-grade uses, final regulatory compliance depends on full formulation assessment—including extraction behavior, end-use conditions, and applicable regional requirements—and must be validated by the compounder or end-user.
