ZG-618 Agricultural Silicone Surfactant – Direct Equivalent to Momentive Silwet 408
ZG-618 agricultural organosilicone super spreader, direct alternative to Momentive Silwet 408. Low surface tension, super spreading, rainfast, compatible with most agrochemicals. Competitive price, free sample & TDS available.
Super Spreading & Penetrating Organosilicone Adjuvant for Agrochemicals
What is ZG-618 Agricultural Silicone Surfactant?ZG-618 is a nonionic trisiloxane ethoxylate-based agricultural silicone surfactant, designed as a high-performance direct replacement for Momentive Silwet 408. It drastically reduces spray solution surface tension to below 21 mN/m (0.1% concentration), delivering unmatched wetting, spreading, and stomatal penetration on plant foliage—matching or exceeding the performance of Silwet 408 at a more competitive cost.
H3（Key Advantages vs. Momentive 408）
1:1 Performance Match: Identical super-spreading, penetration, and rainfastness as Momentive 408, fully compatible with herbicides, insecticides, fungicides, foliar fertilizers, and PGRs.
Cost Advantage: Factory-direct supply, lower MOQ, better wholesale pricing vs. imported Silwet 408.
Stable Supply: 10+ years organic silicone industry experience, consistent quality & fast lead times.
Enhanced Rainfastness: Promotes rapid agrochemical uptake via leaf stomata, reduces wash-off, improves efficacy even after rain.
Wide Compatibility: Nonionic, stable in hard water & oil-based formulations, no phytotoxicity at recommended rates.
