Capa 2200A NPG initiated diol Solvay Caprolactones PU - Polyols >> Caprolactone ADHESIVE >> Water-based CAPA® 2200A is a premium grade linear polyester diol derived from caprolactone monomer, terminated by primary hydroxyl groups. It has a molecular weight of 2000 and a typical OH value of 56 mg KOH /g. It has been specially developed as an intermediate for the production of high quality polyurethane elastomers, where outstanding resistance to hydrolysis is required. NPG initiated diol with faster reactivity : upgraded hydrolysis resistance CAPA® polyols are speciality polyesters particularly suited to polyurethane elastomers and coatings systems as they have a unique blend of properties including good physical characteristics, excellent hydrolysis resistance and outstanding low temperature flexibility. They also offer significant advantages in polyurethane processing, namely consistent reactivity, low viscosity, high purity and ease of processing. CAPA® polyols are used as a soft segment in water borne polyurethane dispersions. These can be typically used to bond soles to uppers. The benefits provided by CAPA® products are: Good high temperature resistance Long open time Good bond strength Good hydrolysis resistance Good adhesion to leather Wide temperature performance Linear polyester diol derived from caprolactone monomer, terminated by primary hydroxyl groups. Possesses fast reactivity and improved hydrolysis resistance. Designed for use in speciality water borne polyurethane dispersions such as adhesives. Used as a soft segment. Provides good high temperature resistance, long open time, good bond strength, good hydrolysis resistance, good adhesion to leather and a wide temperature performance.
