A HISTORY OF POLYUREA

Polyurea

These uses were in RIM (reaction injection molding) and spray application. (The polyurea systems are in wide use in the automotive industry where bumpers, cowlings, side panels, dashboards and other parts are routinely made from polyurea). The polyurea systems are fast systems. They are two component, solvent free and 100% solid. Moisture during the application does not signi�-cantly in�uence the curing performance of the polymer. Likewise, temperature does not present a problem either. As mentioned before, the rapid reaction times presented a barrier to use of the systems for any type of casting, pouring or mobile manual applications. Thus, while the end polymer products exhibited much better performance characteristics than typical polyurethanes, the installation issues caused by the rapid reactions allowed for use of polyurea systems in only a narrow range of situations.

Starting in the mid-80’s Texaco Chemical Company began devoting signi�cant resources to the development of polyurea systems as a complimentary use for their patented raw material known as Je�am-ine. Signi�cant strides were made in developing spray formulations of polyu-rea with set times of 1.5 - 3.0 seconds. Development of industrial uses necessi-tated improvements in processing equipment. Gusmer Corporation, a leading provider of impingement process-ing equipment, worked closely with Texaco in producing innovative equip-ment for delivery of the polyurea systems

Every industry expectation is for geomet-ric growth in the use of polyurea as a coating and sealing elastomer

Over the last 15 or so years a new technol-ogy has been steadily growing in recogni-tion throughout various industries. This technology is an advancement of polymer chemistry based on an earlier chemical family known as polyurethane. The newer technology, known as “polyurea”, takes the form of plural component elastomer systems and has been formulated to provide casting, coating and caulking products that exhibit superior characteris-tics. Plural component elastomer systems have been known for decades. In fact the reactions forming the basis of polymers were discovered about 1850. Actual polymers were formed as early as 1937 and during the 1950’s and 1960’s urethane development was one of the focal points of new discoveries. The use of urethanes as elastomer coatings came to signi�-cance during the 70’s and has continued to command a large share of the coating and sealant market. Urethane technology generally utilizes a catalyst in the systems to promote proper curing. Typical problems encountered with catalyzing systems are moisture and temperature sensitivity. Additionally, catalysts may become a deteriorating element in certain systems. These problems often plague urethane systems. Polyurea does not use a catalytic process, therefore once the chemical reaction has occurred the resulting product is quite inert. However, the extremely reactive nature of polyurea components has formed a general barrier to its use.

Extremely rapid reactions present prob-lems in proper mixing and application. In the early 80’s some of these problems began to be addressed using sophisticat-ed plural component high-pressure equipment.

A HISTORY OF POLYUREA

Caulking and Sealing Products

A detailed analysis of the polyurea technology unmistakably points in the direction of replacement of many urethane systems. The superior character-istics of the polyurea must inevitably be recognized. The higher costs of polyurea will present certain market barriers until evaluated on the basis of performance. The largest challenge in developing polyurea products for caulking purposes has been to maintain the performance characteristics while slowing the reaction times enough to allow for traditional installation. The rapid curing features are a signi�cant selling point, especially where facility shutdown is an issue. Obtaining pot life of up to 5 minutes is pushing the extremes of the slow down potential for these products if they are to maintain the polyurea characteristics and performance.

During the period from about 1990 to 1995 a handful of companies entered the polyurea formulation business. A variety of target markets were identi�ed and several system manufacturers began e�orts at producing slower versions of the polyurea systems with a focus on sealant and caulking products. The greatly improved performance of the polyurea systems provided the impetus for pushing forward with product development. Steady increases in the use of the polyu-rea joint �lling and sealing products have been made over the last several years.

A general consensus has been building among knowledgeable designers of �oor systems that the polyurea joint �lling products exhibit the optimum characteris-tics for long-term performance under heavy use conditions. Several new vendors of polyurea have entered the market, some adding the technology to long standing product lines. Re�nements in the equipment for delivery of the systems have been made and a greater number of experienced contractors make speci�cation of polyurea systems a viable alternative.

A HISTORY OF POLYUREA

Polyurea Coating Products

As we move into the 21st century the uses of polyurea systems continues to expand. The market has moved from negligible to perhaps $50M in annual sales of coating products. Use as waterproo�ng and containment membranes is the leading current use but as the technology becomes more widely understood and the universe of technically pro�cient applicators increases a much broader industrial market is beginning to open. Longer life cycles for infrastructure demands that protective coatings be evaluated as viable alternatives for substrate replacement. The unique physical structure of polyurea membranes places this technology in the forefront for life cycle economic analysis. The compati-bility of these coating systems with various substrate materials such as steel, concrete, wood and other synthesized materials further broadens the horizon of uses. Every industry expectation is for geometric growth in the use of polyurea as a coating and sealing elastomer.

The initial uses of polyurea chemistry were in �xed place impingement molding facilities. The technical advantages of the systems require high-pressure spray application. Only recently have the equipment designs necessary to mobilize the coating potential become commer-cially. At the end of 1995 the market had only a few mobile coating equipment packages capable of applying the polyu-rea systems. Delivery equipment units are somewhat expensive and require techni-cal training to operate and maintain. Nonetheless, protective and specialty coatings based on polyurea represent signi�cant advantages over other coating systems.

The polyurea chemistry is quite resistant to a broad range of corrosives, and cured products exhibit excellent adhesion and abrasion qualities. Perhaps the most signi�cant advantage, certainly the most evident, is the incredibly fast cure time of the systems. Rarely can a protective coating be installed and used within the same 24-hour period. The extremely fast curing aspect of polyurea systems forces a close examination for any application which is constrained by time and temper-ature.
