ENCOR® latexes for textiles and nonwovens
Arkema Coating Resins has traditionally offered formulators a comprehensive range of unique waterborne emulsions for textile coatings, nonwovens and related products, providing:
- Durability
- Protection
- Washing and dry-cleaning resistances
- Tensile and tear strengths,
- Water repellency or permeability
But with increased concern about formaldehyde in textile products, we have developed new formaldehyde-free, self-crosslinking binders designed help meet your innovation and stainability goals. Binders designed to display comparable or even improved performance compared to conventional, formaldehyde-releasing, binders.
Formaldehyde-free polymer design
ENCOR® 1130 S offers performance equivalent to conventional binders. Formulations based on this soft acrylic binder provide:
- Durability
- Protection
- Enhanced appearance
across a wide range of textile surfaces.
ENCOR® 1432 S out-performs conventional binders in the bonding of nonwovens in a number of important performance properties, including:
- Tensile strength in dry and wet (water, alcali) conditions
- Water repellency
This hard styrene-acrylic latex demonstrates a strong affinity for mineral materials, making it ideal for bonding glass mats.
ENCOR® 1133 S gives pigment pastes
- Excellent crockfastness (rubbing resistance)
- Good colour rendering
- Outstanding washing and dry cleaning resistance to printed fabrics
This highly flexible acrylic binder is an excellent choice for applications on stretch fabrics.
Our R&D team is expanding our formaldehyde-free binder portfolio with new products to help you create value in your coatings. The site will be updated as more information becomes available, so please feel free to visit regularly!
