Capa 2402 BDO initiated diol Solvay Caprolactones PU - Polyols >> Caprolactone ADHESIVE >> Hot-melt ADHESIVE >> Solvent based ADHESIVE >> Reactive system ADHESIVE >> Water-based CAPA® 2402 is a linear polyester diol derived from caprolactone and it is terminated by primary hydroxyl groups. It has been specially developed as an intermediate for the production of polyurethane adhesives. It is recommended for applications where short open times and outstanding green strength is required. Polyurethane adhesives based on CAPA 2402 are particularly useful with PVC substrates. BDO initiated diol with faster reactivity 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. Water Based PU's 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 CAPA® polymers are used in the production of moisture cured reactive hot melts. The unique combination of properties means that reactive hot melts with wide ranges of viscosities and bond strengths can be made. Typical end uses are: Bookbinding Textile bonding Structural adhesives Shoes CAPA® polyols are used to produce the prepolymer component in reactive hot melts. This is due to the very low viscosity that CAPA® polyols have when compared to adipate polyesters. This means that much higher molecular weight CAPA® polyols can be used and higher bond strengths achieved. Linear polyester diol derived from caprolactone and terminated by primary hydroxyl groups.
