The Advantages of Non Glycol Based Urethanes for Waterproofing Applications

Posted by Richard Stephens on Aug 14, 2017 11:00:00 AM

Polyurethanes are used to make products with properties ranging from soft flexible foams such as memory foam mattresses, to rigid foams used for house insulation. They can be made into soft rubber as used for skateboard wheels or into very hard enamels as used in modern automobile paints.

 The range of properties can be quite wide, just by changing the chemistry a little, but there's a problem. The traditional chemistry uses materials that have an affinity for water. For applications such as fountains, pond liners, waterproofing, water and waste water tanks, roofing — where long term or constant immersion is an essential requirement — that affinity for water will lead, eventually, to the product swelling or even failing. The reason is in the chemistry, itself. Here’s why.

Figure 1: Durometer Chart

There are several methods for testing the hardness of a coating. One common test method used in both field and lab settings is ASTM D2240 – Durometer Hardness. According to ASTM International, Durometer Hardness determines indentation hardness of substances classified as thermoplastic elastomers, vulcanized (thermoset) rubber, elastomeric materials, cellular materials, gel-like materials, and some plastics.
