Bayhydrol® A 242 is a water-thinnable polyacrylic resin containing hydroxyl groups. It is used as a coreactant for Bayhydur® and Desmodur® polyisocyanates in the formulation of aqueous two-component polyurethane systems for various applications by brush, roller or spray. This product has a viscosity at 23°C, (D = approx. 165 s-1) of 200 ± 100, a non-volatile content (1g, 1h, 125°C) of 42 ± 2, and a pH (10% in demineralized water) value of 7.1 ± 0.7. Bayhydrol® A 242 is a water-thinnable hydroxyfunctional polyacrylic resin with emulsifying properties. It is neutralised with ammonia. Given the special composition of this product, both hydrophilic polyisocyanates, e.g. Bayhydur® 3100, and hydrophobic grades, such as Desmodur® N 3400 and others, are suitable co-reactants. The resultant water-thinnable two-component system cures to yield a polyurethane film with good general properties, and only a small-scale polyurea reaction takes place.

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.
