Capa 2302A BDO initiated diol Solvay Caprolactones PU - Polyols >> Caprolactone ADHESIVE >> Solvent based CAPA® 2302A is a premium grade linear polyester diol derived from caprolactone monomer terminated by primary hydroxyl groups. It has a molecular weight of 3000 and a typical OH value of 37 mg KOH/g. It has been specially developed as an intermediate for the production of polyurethane elastomers with high tear strength. It is also recommended for the production of high quality polyurethane coatings and rapid crystallising adhesives. It offers better hydrolysis resistance and lower odour than CAPA 2302. BDO 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. Solvent Based PU's CAPA® polyols are used in the manufacture of solvent based polyurethane adhesives. They are particularly useful due to the low viscosity and high solids content that can be obtained. Typical end uses are: Bonding Shoe Soles and Uppers Laminated Packaging Textile Bonding Magnetic Tape Adhesive The benefits provided by CAPA® products are: Low viscosity polyols and polyurethanes leads to reduced solvent and VOC. Low viscosity systems aids wet out. Excellent adhesion to different substrate including leather. CAPA® polyols are aliphatic and hence are light stable. CAPA® polyols are non toxic and biodegradable. CAPA® polyester polyols provide excellent oil and UV stability. Very good hydrolysis resistance in comparison with to other polyesters. Low density in comparison with to other polyester based polyurethanes ca. 4%. Excellent low temperature properties and wide working temperature range. Outstanding tear strengths. Linear polyester diol derived from caprolactone monomer terminated by primary hydroxyl groups. Possesses low odor, fast reactivity and improved hydrolysis resistance. Recommended for the production of rapid crystallising adhesives. Provides low viscosity and high solids content in solvent based polyurethane adhesives. Offers very good oil and UV stability and adhesion to different substrate including leather. Applications: bonding shoe soles and uppers, laminated packaging, textile bonding, magnetic tape adhesive.
