Low VOC carpet tile backing coating

As a backing coating for carpets, to adhere and fixate yarns, often a polymer coating is used. This can be bitumen, SBR (Styrene Butadiene) or VAE.

VAE is the most advance backing for tiles, with stronger adhesion and almost no VOC and high flame retardancy.

Several polymers are used as primary and secondary coating for flooring, tiles, carpets and broadloam

There are several coatings that can be used for carpet backing, depending on the specific requirements and intended use of the carpet. Here are some examples:

  1. Latex: This is a common coating used for carpet backing. It is made from natural or synthetic rubber and provides good bonding strength, durability, and resistance to moisture and abrasion.
  2. VAE dispersion that offers increased bonding strength and durability and better properties for recycling, such as water sollubility and being thermoplastic. VAE is also a LOW VOC binder and in basic already low flammable, so it has good FR properties.
  3. Polyurethane (PU): PU coatings are used for carpet backing when a more elastic and flexible backing is required. It offers better resistance to chemicals, oils, and heat than latex coatings.
  4. PVC (polyvinyl chloride): PVC coatings are used for heavy-duty applications where a strong, rigid backing is required. It is resistant to moisture and chemicals, but not as flexible as PU.
  5. Hot melt adhesive: Hot melt adhesive coatings are used for low-pile or commercial carpets. This coating is applied in a molten state and provides a strong bond between the carpet fibers and the backing.
  6. Acrylic: Acrylic coatings are used for indoor/outdoor carpets as they offer good resistance to UV light and weathering.
  7. Bitumen: Bitumen coatings are used for high-traffic areas where extra durability and resistance to wear and tear are required.

The choice of coating will depend on various factors such as the carpet’s intended use, cost, and performance requirements.
