Description
CPU-105-278C-A and CPU-105-278C-B are two-component aliphatic polyurethane polyol mix and isocyanate mix, respectively, without solvent or plasticizer. The resultant elastomer is crystal clear and flexible in nature for doming, coating, encapsulation application, and has good adhesion to various substrates.
Thanks to its specially designed molecular structure, this product has excellent weather resistance and non-yellowing property.
This product complies with RoHS and does not have heavy metals.
Package
20kg/drum or 200kg/drum.
Storage
To avoid the moisture in the air, CPU-105-278C-A and CPU-105-278C-B should be stored in closed containers at room temperature. Avoid direct sunlight exposure.
