FAQ

Q Can RTV2 replicate fine textures in molds?

Yes, its low viscosity and self-leveling properties capture intricate details like fingerprints

Q ‌What surface preparation is required before pouring RTV2 silicone?

Clean the master model with isopropyl alcohol and apply a silicone-free release agent (e.g., PTFE spray) to ensure easy demolding‌

Q How to choose between condensation-cure and addition-cure RTV2 for molds?

Condensation-cure (e.g., RTV-2) suits general-purpose molds, while addition-cure (platinum-catalyzed) is ideal for food-grade or high-detail applications due to zero byproduct release‌

Q How to store RTV2 Liquid Silicone Rubber?

Q How to adjust RTV2 viscosity for specific applications?

Use thixotropic agents or solvents recommended by the manufacturer.

Q Does RTV2 silicone shrink during curing?

Minimal shrinkage (0.1–0.5%) ensures dimensional accuracy.

Q What is the mixing ratio for RTV2?

Common ratios are 1:1, 100:2,10:1, or custom ratios per supplier.

Q What is the Shore hardness range for RTV2?

Typically Shore A 10–60.

Q What is the curing time for RTV2 Liquid Silicone Rubber?

Cure times range from 4–24 hours, depending on formulation.
