<p>PURPOSE:To provide the titled sealing material having excellent forcing sealing workability and remarkably improved performance to repair the leak of piping, by adding a specific amount of light filler to a forcing sealing material based on the sum of the cold-curing agent and a curing agent contained in the material. CONSTITUTION:The objective sealing material is obtained by adding 5- 100pts.wt. (preferably 15-60pts.wt.) of a light filler having a particle density of <=1.0g/cm<2> and particle diameter of <=800mu (preferably hollow particles or foamed article of silica, hollow particles or foamed article of polypropylene, nylon, etc., polyethylene, etc.) to a forcing sealing material based on 100pts.wt. of the sum of the cold-curing resin such as epoxy resin and a curing agent such as polyamideamine, etc. contained in the sealing material. The viscosity of the forcing sealing material is preferably 300-1,000 poise for practical viewpoint. USE:Sealing of gas pipings and water pipings.</p> |
