Wetting and dispersing additive with anti-settling properties for use with ambient cured unsaturated polyester and vinyl ester resins.

  • Physical Characteristics

    AppearanceLiquid, brown
    Non-volatile content50 – 54%
    pH9 – 11 (aqueous emulsion 10%)
    Density0.845 – 0.885 g/cm³ DIN 51757 (20 °C)
    ViscosityN/A
    Solvent(s)Naphtha (Petroleum), Hydrotreated, Heavy

  • Features

    • Improved wetting and viscosity reduction for a wide range of commonly used fillers
    • Shorter paste mixing time and higher filler loading
    • Reduced settling during storage and application
    • Specifically formulated for use with ambient cured unsaturated polyester and vinyl ester resins, minimizing impact on pot life and gel tine drift of the promoted resin

  • Applications

    In the application example below, a commercial DCPD resin used for filled tub and shower applications was dosed with and without Borchi® D-1152 (1.0 % based on filler) and then mixed with 175 phr (parts per hundred resin) alumina trihydrate and calcium carbonate. The results of the resin pastes formulated with Borchi® D-1152 show a significant decrease in viscosity compared to the resin pastes with no wetting and
    dispersing additive.

    Test Method: All measurements were performed at 25°C using a Brookfield viscometer with a vane spindle.

  • Dosage

    0.5 – 1.5 % additive (as supplied) based on weight of filler for improved wetting and viscosity reduction. For optimum performance, mix wetting and dispersing additive into resin before addition of fillers or pigment.

  • Storage

    Please refer to Borchi® D-1152 product label for storage and handling instructions. Store and use material in cool, dry, well ventilated area away from heat, direct sunlight, hot metal surfaces and all sources of ignition. Container must be kept tightly closed immediately after use. Recommended shelf-life is two years from date of manufacture. Separation or turbidity may occur during storage and transportation. Mix well before use. If necessary, warm to 30-60 °C (86-140 °F) and mix well. The product efficiency is not affected.

  • Safety
