(57) [Problem] To provide an aqueous release material composition which can prevent dirt, scratches, damage, etc. without being affected by a working environment or a cured substrate, can be easily released, and does not contaminate a substrate. SOLUTION: (A) A pre-vulcanized natural rubber latex pre-vulcanized with a thiuram-based vulcanizing agent has a solid content of 30 to 30%. 99.9% by weight, and (b) other additives 70 to 0.1% by weight (however, (a) + (b) = 100% by weight), and has a tensile strength of 15 to 100 kgf / cm 2 measured according to JIS K6301; An aqueous release material composition having a coating film performance with an elongation of 15 to 1,000%. |
