Coatings Resins

Coatings resins
Hauthane polyurethane dispersions have been used in various segments of the floor coatings market for many years.  Whether it is wood, concrete, vinyl or composite surfaces, Hauthaway
has a product suitable for the application.

 
Wood Flooring – Including residential, commercial and sports court applications this segment represents a significant portion of the floor coatings market.  It is estimated that 17-19 million
gallons of wood floor coating is applied in North America each year.  About 75-80% of this is water-based coatings.  Performance requirements vary by application, but generally coatings used in this segment need to exhibit superior wear and abrasion resistance, good food stain and house-hold chemical resistance, as well as the aesthetic properties of clarity, warmth and light-stability.  Hauthaway offers several options for formulators to consider.  These include:

- Hauthane HD-2107 – This grade exhibits superior abrasion and light-stability performance in a traditional NMP-containing polymer. The NMP-free, APEO-free counter-part is Hauthane L-2877 (supplied in DMM).
- Hauthane HD-4675 – Designed originally for the California market, this co-solvent free grade offers the formulator the ability to produce low VOC content coatings (below 100 g/l less water). Hd-4675 may be blended with acrylic emulsions to enhance adhesion and provide more economical formulations.
- Hauthane L-3155 – A self-crosslinking grade that matches the performance of a water-based, 2K isocyanate crosslinked product. This polymer exhibits exceptional abrasion and chemical resistance properties in a one-pot system. The NMP-free alternate is Hauthane L-3385 (contains NEP).
- Hauthane L-3415 - A water-based UV-curable grade that produces the ultimate abrasion- and chemical-resistant coating. This product is VOC free as supplied.


Concrete Flooring – Including commercial, industrial and residential applications, this segment is a rapidly growing portion of the flooring market. Here too, the performance requirements vary by end-use, but abrasion resistance and chemical resistance are the most important characteristics for top coats used in this segment. The objective of coatings applicators is to improve appearance (through the use of color and sheen to brighten the space), reduce dusting associated with un-coated concrete and prevent staining of a porous surface. Formulators can select from the following grades.


- Hauthane HD-2117 – A work horse polymer with excellent early water resistance properties, high gloss and easy application characteristics. The NMP-free/APEO-free version is L-2892 (contains DMM).
- Hauthane HD-2125 – A highly chemical-resistant PUD with good gloss characteristics and exceptional durability. The NMP-free/APEO-free version is Hauthane L-2897.
- Hauthane HD-4669 – A co-solvent free, economical PUD with low VOC potential (<100 g/l less water) in formulated coatings.  
- Hauthane HD-4675 –
A harder, co-solvent free, polymer with good exterior durability. This product is also available in a self-coalescing version called Hauthane L-3225.
- Hauthane L-3155 - A self-crosslinking grade that matches the performance of a water-based, 2K isocyanate crosslinked product. This polymer exhibits exceptional abrasion and chemical properties in a one pot system. The NMP-free alternate is Hauthane L-3385 (contains NEP).
- Hauthane L-3524 – A co-solvent free, low temperature coalescing PUD with good early water resistance properties. Coatings formulated with this polymer have low VOC potential (<100 g/l less water).


Composite Flooring – A rapidly growing segment of the flooring market often referred to as engineered flooring. The wear layer of this type of substrate, although said to be maintenance-free , can look tired after a few years of use. Refresher formulas based on polyurethane dispersions offer the do-it-yourself niche an applicator -friendly alternative with minimal floor preparation. Suitable products for this segment include:


- Hauthane HD-2142 – A polyurethane dispersion polymer with an affinity for low energy substrates like polyolefins and TPO. The NMP-free/APEO-free version is Hauthane L-2942 (contains DMM).
- Hauthane L-3155 - A self-crosslinking grade that matches the performance of a water-based, 2K isocyanate crosslinked product. This polymer exhibits exceptional abrasion and chemical properties in a one pot system. The NMP-free alternate is Hauthane L-3385 (contains NEP).

Vinyl (PVC) Flooring – The coatings used in this segment are applied by OEM vinyl flooring producers as well as by the consumer/contractor on site installed vinyl tile. In the former case, the topcoat or wear layer is applied to vinyl roll goods in a factory environment and becomes a permanent part of the substrate. Hauthaway offers two grades for this sub-segment.


- Hauthane HD-2120 – A very hard, chemical resistant grade with exceptional adhesion to PVC. The NMP-free/APEO-free version is Hauthane L-2882 (contains DMM).
- Hauthane L-3415 – A water-based UV-curable grade that produces the ultimate abrasion- and chemical-resistant coating. This product is VOC free as supplied.


In the later case, the consumer or maintenance contractor will apply an alkali strip-able polish -- usually a blend of an acrylic emulsion and a polyurethane dispersion (in higher end polishes). The polyurethane dispersion imparts long-term durability to the coating reducing the amount of maintenance required.

- Hauthane L-2877 - A medium hard, NMP-free, polyester-based grade with exceptional abrasion-resistance properties. 
- Hauthane HD-4675 – A hard, co-solvent free, polyurethane polymer.

As always, Hauthaway’s technical staff is available to discuss your specific application requirements and to make suggestions to help you achieve the optimal balance of properties.
