Capa HC1060 Carboxylic functional diol Solvay Caprolactones PU - Polyols >> Caprolactone ADHESIVE >> Water-based CAPA® HC 1060 is a polycaprolactone polyester diol with a pendant carboxylic functional group. It has a molecular weight of 600 and a typical OH value of 180 mg KOH/g. It has been specifically designed for use in speciality water borne polyurethane dispersions, such as adhesives and coatings. Carboxylic functional diol 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® HC grades have been developed for use in speciality water borne polyurethane dispersions. These products all contain two hydroxyl functions for reaction with isocyanates and a pendant carboxylic group which remains unchanged in this reaction and can be used to disperse the urethane. CAPA® HC grades are all low melting waxes, in comparison with DMPA which is a high melting solid. CAPA® HC grades can be used to replace all or part of DMPA in anionic polyurethane dispersions. 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 Polycaprolactone polyester diol with a pendant carboxylic functional group. Designed for use in speciality water borne polyurethane dispersions such as adhesives. Can be used to replace all or part of DMPA (Dimethylol propionic Acid) in anionic polyurethane dispersions. 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.
