High-protection solvent polyurethanes
Our solvent polyurethanes offer properties such as good adhesion, fastness, and alcohol resistance, and are especially useful as a top coat for shoes and leather goods. They have a range of gloss effects from dull to bright, and they can also be used for upholstery applications. This range also includes a base coat that promotes adhesion and a resin that is also suitable for intermediate coats.
High-gloss patent systems
Stahl’s patent systems for use on top coats include polyisocyanate, polyester pigmented polyol, and polyester polyol resins that form films ranging from soft to very hard. They all have high glosses and are particularly useful for shoes and leather goods applications, but also for garments. They offer various colors and deep transparencies, and often act as crosslinkers and produce a natural, smooth feel. SU-8220 is especially recommended for white and pastel shades, where EX-SU-8265 has high thermosetting resistance.
Our solvent polyurethane resins are part of our Stahl Neo® portfolio, which means that they comply with the ZDHC MRSL.
