Solvent vs Water Based Coating

-

The choice between solvent-based and water-based coatings depends on various factors, such as intended use, environmental considerations, performance requirements, and regulatory compliance. 

A solvent-based coating is a type of coating that uses organic solvents as the primary carrier. The organic solvents serve as a medium to disperse the other components of the coating. When the coating is applied, the solvents evaporate, leaving behind a solid film of resins and pigments on the surface. 

A water-based coating, as the name suggests, uses water as the primary carrier instead of organic solvents. When the coating is applied, the water evaporate, leaving behind a solid film of resins and pigments on the surface.

TORO coated fabric are available in both water and solvent based coating options

Solvent-Based Coatings:

  1. Composition:

    • Organic solvents
    • Resins
    • Pigments
    • Additives
    • Volatile organic compounds (VOCs)

  2. Environmental Impact:

    • Higher VOC content
    • Contributes to air pollution
    • Poses health and environmental risks

  3. Application and Drying:

    • Requires specialized equipment
    • Higher viscosity
    • Dries by solvent evaporation, relatively fast

  4. Odor and Toxicity:

    • Strong odor
    • Prolonged exposure to fumes can be harmful

  5. Flammability:

    • More flammable than water-based coatings
    • Requires special precautions for handling and storage

  6. Durability:

    • Excellent resistance to chemicals, weathering, and abrasion

  7. Regulatory Compliance:

    • Stricter regulations due to VOC emissions

Water-Based Coatings:

  1. Composition:

    • Water
    • Resins
    • Pigments
    • Additives
    • Sometimes co-solvents in small amounts

  2. Environmental Impact:

    • Lower VOC content
    • More environmentally friendly
    • Safer to use

  3. Application and Drying:

    • Various application method
    • Lower viscosity
    • Dries through water evaporation, sometimes curing process

  4. Odor and Toxicity:

    • Minimal odor
    • User-friendly, suitable for indoor applications

  5. Flammability:

    • Less flammable than solvent-based coatings
    • Reduces fire hazards

  6. Durability:

    • Advancements made, slightly lower compared to solvent-based coatings

  7. Regulatory Compliance:

    • Lower VOC content, more compliant with environmental regulations

Exploring the World of Coated Fabrics

-

Coating is a process in which a polymeric layer is applied directly to one or both surfaces of the fabric. The polymer coating must adhere to the textile and a blade or similar aperture controls the thickness of the viscous polymer. The coated fabric is heated and the polymer is cured (that is, polymerized). Where a thick coating is required this may be built up by applying successive coating layers, layer on layer, Interlayer adhesion must therefore be high. Finally, a thin top layer may be applied for aesthetic or technical enhancement of the coating. The coating serves various purposes, depending on the desired properties of the final fabric. It can provide protection against water, moisture, chemicals, or UV radiation. It can also improve the fabric's durability, strength, and resistance to abrasion or tear. Additionally, the coating can alter the fabric's appearance by adding texture, gloss, or other visual effects.   Depending upon the end-us

TORO presents a diverse range of substrates, allowing for countless opportunities to skillfully match material characteristics with the specific requirements of customers' applications. Depending on the desired performance attributes for a particular use, our substrates can be crafted through knitting, weaving, or non-woven techniques. Here is the list of commonly used substrates for coating. Cotton:     Natural cellulosic fiber exhibits good abrasion resistance.     It demonstrates good adhesion to rubber compounds.     It possesses excellent resistance to alkalis, although it degrades when exposed to hot acids.     The fiber remains resistant to melting even at high temperatures. Polyester:     This multifunctional synthetic fiber has the ability to absorb oil and grease.     It exhibits excellent abrasion resistance.     The fiber is resistant to various chemicals.
