Industrial Caulk and Seal (ICS) recently announced that, as of last month, it had installed over 1 million linear feet of semi-rigid joint filler through the previous 12 months.

Evonik recently announced that it will present six papers and one technical poster at the 2019 edition of The Center for Polyurethanes Industry’s (CPI) annual Technical Conference, which is taking place October 7-9 in Orlando, Fla.

Isocyanates react with compounds that have active hydrogens. For example, in coating applications, isocyanates are typically reacted with polyols to form polyurethanes, or with primary and secondary amines to form polyureas. Catalysis of the polyol/isocyanate reaction, which is often required to develop sufficient cure response, can be achieved with a variety of compounds.

America’s infrastructure GPA stands at a D+, with an estimated $3.6 trillion of work needed by 2020 to repair the country’s out-of-date structures, bridges, roads, etc.1 Part of these issues lie within public parks and recreation, which are being used by a reported 140 million Americans on a daily basis.

Concrete is the most widely used building material in the world, due to its versatility, durability and ease of use. But it is also predisposed to developing random cracks, which quickly become arteries for water, salts, chemicals and other foreign materials to seep in.

What types of chemical structures could be built into a polyurethane adhesive to optimize heat resistance? Can you make any formulation recommendations?

The Center for the Polyurethanes Industry recently announced the finalists for the 2015 Polyurethane Innovation Award.

The most important difference is that the polyurea reaction is much faster than the polyurethane one.
