Dow introduces a new additive for improved foam control in premium low to medium-PVC water-based coatings and inks

Throughout the entire process of producing, filling and applying waterborne systems, foam generation can cause severe problems in the end result.

In cases where efficient defoaming is needed and the final surface appearance is critical to your system, consider DOWSIL™ 108F Additive.

About DOWSIL™ 108F Additive

DOWSIL™ 108F Additive is a highly efficient defoaming agent for waterborne systems. The siloxane-based emulsion is designed to deliver an optimized balance of foam control and compatibility in a wide variety of waterborne coatings and inks. Plus, its diluted delivery form makes it very easy to dose and use.

While DOWSIL™ 108F Additive can deliver excellent results in a wide variety of waterborne paint and ink systems, it is specifically designed for use in premium gloss applications, such as wood coatings, industrial coatings and inks, where its low tendency to cause craters or other surface defects is especially valuable.

In addition, the APEO-free and low-VOC nature of DOWSIL™ 108F Additive is of clear relevance to specific end users.

  • DOWSIL™ 795 Silicone Building Sealant
    A one-part, cold-applied, non-sagging silicone material that cures to a medium modulus silicone rubber upon exposure to atmospheric moisture.

  • DOWSIL™ 791 Weatherproofing Sealant
    A one-part, medium-modulus, elastomeric sealant designed for general weathersealing. It is a silicone formulation that cures to a flexible and curable silicone rubber building joint seal.

  • XIAMETER™ PMX-1501 Fluid
    A blend of an ultra high viscosity dimethiconol in cyclopentasiloxane for use in skincare, suncare, haircare, antiperspirant and deodorant, and color cosmetic applications. INCI Name: Cyclopentasiloxane (and) Dimethiconol

  • DOWSIL™ 556 Cosmetic Grade Fluid
    A polyphenylmethylsiloxane for use in skincare, suncare, color cosmetic, hair care, and antiperspirant / deodorant applications. INCI Name: Phenyl Trimethicone

  • DOWSIL™ 995 Silicone Structural Sealant
    A one-component, self-priming, shelf-stable, neutral-cure, elastomeric adhesive specifically formulated for silicone structural glazing and exhibits excellent unprimed adhesion to most building substrates. This product has superior unprimed adhesion for structural glazing applications for hurricane or impact rated windows and doors. It has a movement capability of +/- 50%.

  • XIAMETER™ PMX-200 Silicone Fluid 350 cSt
    100% active, 350 cSt, polydimethylsiloxane polymer. INCI Name: Dimethicone

  • DOWSIL™ 1200 OS Primer
    An air drying primer supplied as a dilute solution of moisture reactive materials in volatile siloxane and is used to improve both the quality and speed of adhesion development to room temperature vulcanizing silicone sealants to a variety of common non-porous substrates.

  • DOWSIL™ 983 Structural Glazing Sealant Base and Curing Agent

    Designed for specialized use where dual structural and weatherseal applications are desired for factory glazing and curtainwall production. Once cured, this structural sealant forms a durable, flexible, watertight bond that can be warranted for 20 years and used in ±25% movement weatherseal applications. It has excellent unprimed adhesion to glass, alodine, and anodized aluminum1, although DOWSIL™ Primer-C OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications.

  • DOWSIL™ 890-SL Silicone Joint Sealant
    A one-part, cold-applied, easy-to-use, self-leveling silicon material that cures to an ultra-low-modulus silicone rubber upon exposure to atmospheric moisture. The cured silicone rubber remains flexible over the entire temperature range expected in pavement applications.

  • SYL-OFF™ 4000 Catalyst
    General purpose catalyst which is compatible with all Syl-off® brand solvent based and solventless release coating systems as well as Plantinum cure silicone PSAs.
