UNIRETHANE highly functional, high performance urethane coatings

The following section provides an introduction to UNIRETHANE, the raw material in the UNIRETHANE Series of improved urethane coatings, uniquely developed and supplied by the UNICS Corporation. Please take a moment to look through the overview of UNIRETHANE below, as well as details of its features, test data and example applications. It is well worth taking a look at TEFTHANE, our coatings with improved non-stick properties, at the same time

UNIRETHANE two-component hand-spray polyurethane raw materials

In an effort to satisfy a wide range of performance requirements from customers, and to improve workability and quality for installing engineers, we used urethane coating technologies built up over many years at UNICS to develop a highly functional, high performance raw material for polyurethane coatings. That is UNIRETHANE.

We have products with amazing abrasion resistance, and can help to reduce location, equipment and associated costs for two-component installation that hardens at ambient temperatures. Our products also help to improve the efficiency and life span of machinery, equipment and parts. We have products tailored to improve functionality, performance, application and price, in order to increase operating efficiency, enhance quality and reduce overall costs. We recommend trying our products at least once.

The most important feature of UNIRETHANE is its abrasion resistance

UNIRETHANE is a material that is strong yet light and flexible at the same time. It also offers outstanding abrasion resistance compared to other industrial materials. US3000 in particular offers a level of abrasion resistance that would be unimaginable for regular polyurethane, making it suitable for applications such as devices with heavy wear and tear.

*Abrasion tests conducted in accordance with “JIS K 7204:1999 Testing Method for Abrasion Resistance of Plastics by Abrasion Wheels” (Taber Test) Test load: 4.9N Abrasion wheels: H18 Test cycles: 1,000

Highly resistant to chemicals, saltwater, oil and heat too

UNIRETHANE has outstanding chemical resistance in the range PH4-10, and performs well against most oils and saltwater too, making it suitable for applications such as water filters and marine equipment. It also offers heat resistance up to 80-90 degrees centigrade , compared to an upper limit of 70-80 degrees centigrade for general-purpose polyurethane. Water resistance tests have shown that US3000 is resistant up to 100-120 degrees centigrade. Properties such as these are opening up applications across an increasingly wide range of fields.
