Product introduction

    YW4008 is modified oligomers pure acrylic resin as the main resin, the molecular weight of 20,000 - Between 25,000 intramolecular cohesive energy big, strong bonding, while the molecular chain length and containing a hydrophobic group, showing the macroscopic properties of materials good, such as adhesion, flexibility, water resistance and chemical resistance, since the main functional group containing allyl double bond, radiation curable or chemically crosslinked, have light color transparent, translucent non-yellowing; wide range of applications, both used as a binder for UV light curable coatings, inks and laminating adhesives and other products, but also systems and other acrylic, epoxy, polyurethane, nitro and other materials blended to improve the bonding strength of the material, flexibility, water resistance and yellowing transparency have a significant effect.
