Lanxess Launches High-Performance Protective Coatings

High-Performance Protective Coatings from Lanxess As polyurethane systems become more widespread and the need for PU materials increases, industry demand for raw materials and solutions in this field is also rising. Polyurethane materials, which provide considerable benefits both in industry and in everyday life, consist of two main components: polyol and isocyanate. Lanxess Urethane Systems is a global leader in solvent-free, water-based, and low-free isocyanate block systems for elastomers, coatings, adhesives and sealants in polyurethane systems. Lanxess, which includes Witcobond®, Adiprene®LF, Vibrathane® and Trixene® product lines, provides different and sustainable solutions to the sector. Trixene® urethane prepolymers and components can be used for formulations of 1K and 2K liquid-applied protective coatings and waterproofing systems. These products are designed under a comprehensive portfolio combining elastomer and coating expertise. Trixene® urethane prepolymers and components provide certain advantages to industry during use, in addition to their technical properties.

Advanced Industrial Hygiene

Trixene® urethane systems provide advanced industrial hygiene during transport and use. These urethane prepolymers protect formulators and end users from potential exposure to residual isocyanate; minimize the burden in terms of environment, occupational health and safety; and enable the formulator to obtain final formulations with reduced hazard classifications. This product line also includes water-based and high-solids prepolymers with reduced VOC content that minimize toxicity and flammability risks for contractors and building owners.  

Easy Processing

Trixene® urethane prepolymers and components are used to formulate low-viscosity, field-applied 1K and 2K protective coatings for application at ambient temperature. These products result in final formulations that eliminate the flame and heat requirements often necessary during conventional waterproofing installations using sheet materials and facilitate application over complex design features such as railings and support columns. To reduce installation costs, they can be applied by brush, roller or spray, and even wet-on-wet application. Final products can be designed by formulators for each season and weather condition to achieve the required reactivity and cure profiles.

Excellent Performance

Trixene Prepolymers and components are critical components for 1K and 2K urethane liquid-applied systems that result in continuous and seamless protective coatings and waterproofing membranes, and can be used in roofing applications including flat roofs, hot&cold roofs, inverted roofs and green roofs. These products provide formulators with excellent UV stability, strong adhesion to multiple substrates and the ability to provide durable mechanical properties while resisting environmental stresses.  

Wide Range of Product Lines for High-Performance Protective Coatings

Trixene® prepolymers and components offer versatility for the formulator with low-free isocyanate technology, high solids, low odor and low VOC. They enable the production of 1K and 2K PU, PUMA and SPUR coatings and waterproof coatings that meet the challenges and demands of high-performance construction materials.

For 1K Polyurethane Construction Coatings

Trixene® prepolymers offer a range of properties that can be used to design specialized formulations for liquid-applied waterproofing systems and protective coatings. • Traditional and low-free isocyanate prepolymers for advanced industrial hygiene for both formulators and end users, • Aromatic (TDI, MDI) prepolymers for durability and cost-effectiveness, • Aliphatic prepolymers (IPDI, HDI) for performance and improved light fastness, • Water-based (PUD) dispersions and 100% solids prepolymers to meet low VOC requirements, • Room temperature, low-viscosity, 100% solids and low-odor solvent-containing prepolymers, • Products suitable for formulation of both clear and pigmented coatings.  

Additives for Use in 1K and 2K Urethane Waterproofing Formulations

Lanxess offers a range of additives that can improve formulations for liquid-applied waterproofing systems. *Trixene® As and ASF are used as moisture scavengers in moisture-cured 1K systems to prevent pinhole defects on coating surfaces and increase the stability of formulated systems.

Low-Free Isocyanate Prepolymers Produce Highly Structured Elastomeric Coatings for Enhanced Performance

Trixene® low-free isocyanate prepolymers are chemically engineered to provide superior performance including excellent toughness, fatigue resistance and longer service life when exposed to extreme temperatures and chemicals. They are used in various coatings, adhesives and sealants. • Narrow molecular weight distribution for viscosity control and processing, • A strong cross-linked network is formed, • More defined phase separation between hard and soft segments, resulting in better physical properties as evidenced by tensile and tear strength due to increased orientation and stress-induced alignment.   Özlem Erkan Asmaoğlu Technical Sales Engineer, PU & Coatings Additives Kimsel Kimya
