PURPOSE:To prevent generation of stripping, craze, etc. by mixing a plasticizer, higher alcohol and a specific hydrocarbon polymer which is liquid at a room temp. with a specific hydrocarbon polymer which is solid at a room temp. as a paint coated film material. CONSTITUTION:A paint coated film material 4 of a caulking tube 1 is prepd. by mixing 10-500pts.wt. org. compd. composed of a plasticizer such as phthalate, higher alcohol and a specific hydrocarbon polymer which is liquid at an ordinary temp. with 100pts.wt. hydrocarbon polymer which is satd. with a main chain having >=1 hydroxyl group at the terminal and is solid at an ordinary temp. The caulking tube has better sealing capacity of its plunger and is free from generation of stripping, craze, etc. in the paint coated film in the stage of inserting the plunger therein. |
