Q1: What is the primary function of DOWSIL 9045 in silicone elastomer formulations?
A: DOWSIL 9045 is a pre-blended silicone elastomer system designed to enhance processing efficiency and improve surface quality in high-consistency rubber (HCR) and liquid silicone rubber (LSR) applications. It functions as a process aid and surface modifier, helping to reduce mold fouling and improve release characteristics without compromising mechanical performance.
Q2: Is DOWSIL 9045 compatible with both platinum-cured and peroxide-cured silicone systems?
A: Yes, DOWSIL 9045 is formulated for broad compatibility across common silicone curing chemistries, including platinum-catalyzed addition-cure and peroxide-cure systems. However, optimal performance and cure kinetics should be verified under actual processing conditions due to formulation-specific interactions.
Q3: How is DOWSIL 9045 typically incorporated into a silicone compound?
A: It is generally added during the final mixing stage—after base polymer, filler, and curative—using standard dispersion equipment such as two-roll mills or internal mixers. Due to its elastomeric nature, it integrates readily without requiring extended shear or elevated temperatures.
Q4: Does DOWSIL 9045 affect the thermal stability or compression set resistance of the cured elastomer?
A: When used at recommended levels, DOWSIL 9045 maintains the inherent thermal stability and low compression set typical of high-performance silicone elastomers. It is not intended to serve as a primary reinforcing agent, so significant changes to these properties are generally not observed under standard formulation practices.
Q5: Can DOWSIL 9045 be used in medical-grade or food-contact silicone applications?
A: DOWSIL 9045 is designed for industrial and general-purpose elastomer modification. For regulated applications—including medical devices or food contact—it must be evaluated in the final compounded system against applicable regulatory requirements, as compliance depends on full formulation, processing, and end-use conditions.
