Capa® 2043

Technical Datasheet | Supplied by Ingevity
Standard grade low molecular weight, linear polyester diol derived from caprolactone monomer (terminated by primary hydroxyl groups). Exhibits excellent solvent-, chemical- and UV resistance, consistent crystallization and low viscosity. Possesses hydrolytic stability, gloss, excellent strength, abrasion resistance and high and low temperature service interval. It shows outstanding flexibility even at low temperatures and a lasting outdoor performance for polyurethane materials. Shows strong adhesion on difficult and sensitive substrates. It is non-toxic, easy to process, shape and apply, biodegradable and has low impurities. Recommended for use in low VOC and environment-friendly polyurethane surface coatings, such as polyurethane dispersions, high solid and UV-cure resins. Applications include industrial, automotive, transportation, marine, protective, electronic, leather, surface, and textile coatings. Also suitable for non-polyurethane coating industries.
