Product Details
A-RTV-3020 Silicone Elastomer (Shore A 20, 10:1 RTV)
A-RTV-3020 is a platinum-cure, two-part silicone elastomer with a Shore A 20 durometer, designed for applications requiring flexibility, detail reproduction, and reliable performance. This 10:1 mix ratio system cures at room temperature to form a translucent, durable elastomer.
Its low viscosity, pourable consistency allows for easy processing and excellent mold detail capture. The material can also be modified with thixotropic agents to achieve a non-sag consistency when needed.
A-RTV-3020 offers excellent adhesion to acrylic and various substrates, making it a versatile choice for bonding and casting applications.
