Name: Dow SILASTIC LCF 9618 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow SILASTIC LCF 9618 Defoamer

Highly effective silicone-based defoamer specifically engineered for low-foaming performance in demanding liquid silicone rubber (LSR) processing.
Excellent compatibility with platinum-cured LSR systems, minimizing risk of catalyst inhibition or cure interference.
Provides rapid foam collapse and long-term foam suppression even under high-shear mixing and injection conditions.
Low-volatility formulation ensures minimal residue and reduced odor during high-temperature vulcanization.
Easy dispersion in LSR base polymers without requiring pre-dilution or specialized handling equipment.

Typical Applications Of Dow SILASTIC LCF 9618 Defoamer

Automotive LSR components including gaskets, seals, and sensor housings.
Medical-grade LSR parts such as syringe plungers, respiratory masks, and tubing connectors.
Consumer electronics encapsulation and overmolding where surface aesthetics and bubble-free finish are critical.
Industrial fluid-handling components requiring high purity and consistent dimensional stability.
Food-contact compliant LSR applications meeting FDA 21 CFR §177.2600 requirements when formulated accordingly.
