  • Additives for use in low surface-energy applications
    Patent number: 12371549
    Abstract: Fluorine-free small molecule additives of structure where X1 and X2 are independently hydrocarbyl or heterohydrocarbyl; and Q1 and Q2 are independently —Si—(O—Si(CH3)3)3 or —(O—Si(CH3)2)n—O—Si(CH3)3 and where n is an integer from 0 to 30, inclusive for use in solid-state formulations, e.g., thermoplastic articles, for use in low hysteresis water repellent applications. Methods of preparing such compositions and additives.
    Type: Grant
    Filed: December 21, 2022

  • COMPOSITIONS FOR USE IN LOW SURFACE-ENERGY APPLICATIONS
    Publication number: 20250034356
    Abstract: Fluorine-free and silicone-free small molecule additives of structure (I) where each of R1, R2, R3, and R4 is independently a 12 to 50 carbon alkyl group, optionally a 14 to 40 carbon alkyl group, or optionally an 18 to 30 carbon alkyl group for use in solid-state formulations, e.g., thermoplastic articles, for use in low hysteresis water repellent applications such as ultra-repellent surfaces. Methods of preparing such compositions and additives are provided.
