What is Cured Inhibition in Urethanes?
Certain urethane systems may be affected by the type of silicone mold you cast into. Tin based silicones (condensation cured) are known to cause issues with many Shore A Elastomer urethane systems and also Aliphatic urethanes (e.g. our Water Clear materials). Silicone mold material must be carefully selected depending on the urethane system you plan to cast. Casting a urethane into an incompatible silicone can be an expensive disaster; both money and time.
