Abstract
Provided are an abrasive tape suitable for finishing of surfaces or the like of precision components such as optical connector ferrules and semiconductor wafers, and a process for producing it. A coating agent in which abrasive particles having an average particle size in the range of 1 to 200 mμ are dispersed in a binder resin solution. The coating agent is applied, with intervention of a primer layer if necessary, onto a base for abrasive tape to form an abrasive layer, thus obtaining an abrasive tape.
Claims22
An abrasive tape comprising:
- a base for abrasive tape;
- and
- an abrasive layer formed on the base;
- wherein the abrasive layer is formed from a coating agent in which abrasive particles of an average particle size in the range of 10 to 100 mμ are dispersed in a binder resin solution.
A process for producing an abrasive tape, comprising the steps of:
- dispersing abrasive particles of an average particle size in the range of 10 to 100 mμ in a binder resin solution,
- producing aggregates of the abrasive particles in the binder resin solution to obtain a coating agent containing the abrasive particles of particle diameters 50 to 800 mμ, and
- applying the coating agent onto a base for abrasive tape.
An abrasive tape comprising:
- a base for abrasive tape;
- and
- an abrasive layer formed on the base;
- wherein said abrasive layer has abrasive particles of an average particle size in the range of 1 to 200 mμ and a binder for binding the abrasive particles.
A coating agent for production of an abrasive tape, comprising:
- an abrasive particle solution containing abrasive particles of an average particle size in the range of 1 to 200 mμ and a solvent for abrasive particles, and
- a binder resin solution containing a binder and a binder solvent.
A process for producing an abrasive tape, comprising the steps of:
- preparing a base for abrasive tape;
- mixing an abrasive particle solution containing abrasive particles of an average particle size in the range of 1 to 200 mμ and a solvent for abrasive particles, with a binder resin solution containing a binder and a binder solvent to produce a coating agent;
- applying the coating agent onto the base for abrasive tape;
- and
- drying the coating agent thus applied.
