Bostik Vitel® 3350B is an amorphous, linear, saturated polyester with solubility in certain common solvents (e.g. Ethyl acetate, MEK, Toluene). V3350B is a low Tg polymer that is designed to be used as part of a solvent-based laminating adhesive. The low glass transition temperature yields highly flexible films. The Tg can be modified to meet application requirements by blending this product with other Vitel® resins and can be used as a modifier in other Vitel® formulations to impart flexibility and improve adhesion.
FEATURES of Bostik Vitel® 3350B
- Low glass transition temperature
- Good adhesion to variety of substrates: PET, metals, vinyls and treated olefins (PP or PE)
- Good flow characteristics
BENEFITS of Bostik Vitel® 3350B
- Excellent flexibility
- Compatible with other Vitel® resins to formulate to achieve desired performance
- Good solution stability
