Polyurethane Acrylate UV Resin T-7770
T-7770 resin is recommended for use on the surfaces of organic and inorganic materials that are difficult to adhere to, such as glass, oxidized metals, copper-clad laminates, etc. It has strong toughness and relatively high surface hardness. Better temperature resistance (temperature resistance 260-300℃), no loss of luster and matte color after high temperature. It is used in the instant high temperature of circuit board wave soldering, high temperature curing of wine bottle decals and other inks, and high temperature adhesive for electronic bonding.
T-7770 is used as a high-temperature UV adhesive, which can provide the most ideal bonding strength and water resistance. It does not contain monomers, has no irritating odor, and has fast curing and low shrinkage. In UV coating applications, it is used as the main resin of vacuum plating UV primer for glass packaging products, BMC car lamp coatings with high temperature requirements, and high temperature metal UV coatings. In the field of UV ink, it is used in organic and inorganic material UV screen printing ink to enhance adhesion properties. Used in UV ink for special circuit boards.
