Phenoxy PK™HM-301 is a solid-grade phenoxy PKHC resin melt blended with an oligomeric polyester polyol containing primary hydroxyl functional groups. Phenoxy resins (polyhydroxyethers) are tough, ductile, amorphous, thermoplastic polymers having excellent thermal stability, adhesive strength, and vapor barrier properties. Phenoxy resins may be crosslinked by reacting its hydroxyl functional groups with isocyanates, melamine resins, or phenolic resins. Crosslinked phenoxy resins exhibit excellent chemical resistance, hardness, and adhesion on many substrates including steel, aluminum, glass, and carbon fibers, and plastics such as nylon and polyester (PET).
PK™HM-301 provides for improved reactivity due to the presence of primary hydroxyls and the lower glass transition temperature of the alloy. PK™HM-301 has a glass transition temperature of about 35 °C which imparts improved solids/viscosity ratios in common solvents like MEK. Coatings of PK™HM-301 exhibit high levels of flexibility and formability when appropriately cured.

Lists combine the ease of Bookmarks with the versatility of Tags. Instead of one collection of bookmarked items, create as many collections, called "Lists," as you need.
Find the link to your List page in the user menu.
All Tags have been converted to separate Lists, and your bookmarked items have been saved to a "Bookmarks" List.
When you click the Add to List button, a dropdown of your existing Lists appears. Click the List name to which you want to add this product or formula.
You can also create a new List. Simply click "Create a New List" and enter a name.
When you define a new List, the current item is automatically added to it. You can add a product or formula to as many Lists as you need.
Easily see which Lists this item appears in, and quickly go to that List from the links that appear on the page.
