PURPOSE: To provide a stripping agent which has is low in toxicity, good adhesion to the surface of an adherend, a potent effect of inhibiting the evaporation of solvents contained therein and excellent stripping characteristics, by blending acetone, hydroxypropylcellulose and wax.
CONSTITUTION: A stripping agent consists of acetone or a solvent mixture of acetone and ethyl alcohol. Acetone used in the agent is a preferred main solvent which is relatively low in toxicity as a stripping agent for 2-cyanoacrylate adhesive. Ethyl alcohol may be mixed as a co-solvent to increase the solubility of hydroxypropylcellulose. Hydroxypropylcellulose plays chiefly a role of inhibiting the evaporation of the solvents after thickening and film formation. By inhibiting the evaporation of the solvents, the agent can retain a suitable viscosity and adhere well to the surface of an adhered, and hence the solvent action on a cured adhesive can persist.
