VESTANAT T 1890 is a cycloaliphatic polyisocyanate based on isophorone diisocyanate (IPDI). It contains isocyanurate groups and has a NCO-functionality between 3 and 4 VESTANAT T 1890 is used as a crosslinker in 2K-PUR paints based on suitable polyesters, acrylates, flexible medium-oil or short-oil alkyd resins and other resins containing OH-groups.
In combination with suitable polyols, polyurethane paints with outstanding weather resistance and light fastness are obtained. Typical applications are automotive OEM and car repair paints, fleet coatings, maintenance coatings, etc.
• Excellent compatibility & high reactivity
• Durability against environmental impacts
• High compatibility
• UV resistant, lightfast and very good gloss retention
• First-class chemical resistance
• High reactivity even at ambient temperature
• Short curing cycles
VESTANAT T 1890 is available in n-butyl acetate (VESTANAT T 1890 E), n-butyl acetate / solvent naphtha (VESTANAT T 1890 L), and solvent naphtha (VESTANAT T 1890 SN). Each is a low to medium viscosity liquid. VESTANAT T 1890 is also available as a solvent-free, solid material (VESTANAT T 1890/100).

DYNAPOL® stands for high quality polyester resins for the coatings industry with a product portfolio containing high and medium molecular weight saturated co-polyesters. Whichever way you look at this unique polyester product range, its depth and diversity are unrivalled. These coating raw materials are suitable to produce coating systems with very good adhesion offering an optimum of flexibility together with an excellent surface hardness.
· DYNAPOL® L: High molecular co-polyesters
· DYNAPOL® LH: Medium molecular co-polyesters in solution
· DYNAPOL® UB: Blocked one pack polyester-polyurethane systems
· DYNAPOL® LS: Highly flexible co-polyesters
Evonik’s DYNAPOL® resins are used in coil coating (topcoats, backing coats, or primers), in rigid metal packaging (primers, pigmented coatings, and clear coats) and in flexible packaging applications such as foil- and pre-print primers, printing inks, overprint varnishes, foil coatings, heat-seal lacquers and interlayers. They are also used as additives in different flexible packaging formulations to improve properties like printability, adhesion, flexibility, and hardness.

Evonik has developed a new crosslinking concept for high performance, scratch resistant coatings based on adducts of isocyanatosilanes. This class of silaneurethane hybrid crosslinkers exhibits an outstanding performance profile with regard to both mechanical and chemical properties. The temperature sensitivity of the substrate and the desired curing conditions determine the choice of crosslinker.
• Outstanding scratch resistance
• Up to 100% active matter
• Fast curing cycles
• High chemical resistance
• Room temperature curing
• DIY possible
A toolbox for custom-designed solutions, the technology platform opens up a wide range of possibilities to formulate scratch resistant low temperature cure coatings for a plethora of substrates such as wood, plastic and metals and many more. Imagine formulating a coating with scratch resistance and durability like a diamond.
Evonik's saturated polyesters are used as a resin or as an additive in many flexible packaging applications, such as foil and pre-print primers, printing inks, overprint varnishes, foil coatings, heat-seal lacquers, and interlayers.
The high molecular weight DYNAPOL L grades show excellent adhesion to a variety of different foil substrates made of aluminum, PET, PC, and PA, and offer outstanding film flexibility. Properties like molecular weight, softening point, glass transition temperatures and balance between flexibility and hardness can be tailored in a wide range to meet special customer requirements.
The following are just some of the advantages of formulating with DYNAPOL polyesters:
• Improved printability
• Outstanding adhesion
• Excellent balance of hardness and flexibility
• Low migration
• Free of taste and smell
• Non-yellowing
