What are the characteristics of RTV-2 mold adhesive?

① The cultural stone mold adhesive should have good operational performance.
② Silicone has better flowability and low viscosity, making it easy to operate.
③ The smaller the shrinkage rate of silicone rubber, the better.
④ Silicone rubber has better tensile strength.
⑤ The silicone mold made should not deform.
⑥ The hardness of silicone rubber should be suitable for product use.
⑦ High temperature resistance, multiple mold turns, longer service life, better, acid, alkali, and aging resistance.
