The Studies of Phusical properties on the Performance of the Removal Type Pressure-Sensitive Acrylic Adhesive
We were investigated performance of pressure-sensitive acrylic adhesive that blending of acrylic adhensive by batch reactor. and we examinated viscosity, temperature, heat treatment rate and peel adhesion. When the peel adhension is 160gf/25mm we know that optimum blending ratio is 1.3:1 as acrylic adhensive/solvent, that is shown hightest generality. When viscosity range of adhensive is 1000 ~ 2000cps, peel adhension of removal type adhensive show about 160gf/25mm. For non-volatility after drying is 30%, viscosity show the optimum property so that we know a room temperature curing adhensive. Pot life is 30 sec. as a heat treatment rate at 50m/min, therefore minimum curing time is 30 sec. Not only weathering resistance keep up peel adhension 160 ~ 180gf/25mm after 1,000hrs, but also no residual remains.
