Platinum Cured Silicone

Platinum Cure RTV-2 Silicone Rubber

Platinum cure silicone rubber is widely chosen for high-detail molds, lower shrinkage requirements, better dimensional stability, and premium finished mold performance. It is often used in precision mold making, selected food mold projects, and rapid prototyping applications.

When Platinum Cure Makes More Sense？

Platinum cure silicone is usually preferred when lower shrinkage, better dimensional stability, and cleaner detail reproduction matter. It is often chosen for high-detail molds, repeated mold use, and projects where performance is more important than lowest initial cost.

Key Benefits

Lower Shrinkage

Useful for projects where detail accuracy and long-term mold stability matter.

Better Dimensional Stability

Often preferred in prototype work and premium mold making where repeatability is important.

Cleaner Finished Mold Quality

Helps deliver a refined mold surface in many detail-sensitive applications.

Fit for Higher-End Applications

Can be a strong choice for precision molds, selected food mold projects, and premium commercial mold production.

Best-Fit Applications

Precision resin mold making

Selected food mold applications

Rapid prototyping and vacuum casting molds

Important Note About Cure Inhibition

Platinum cure silicone can be sensitive to certain contaminants. If your master pattern contains sulfur clay, latex, certain paints, uncured resin, or unfamiliar surface coatings, curing may be affected. In these cases, a small test cure is strongly recommended before full pouring.

This is not a weakness if handled correctly, but it does require better process awareness than many general-purpose systems.

How to Choose the Right Platinum Grade？

Choose by Hardness

Softer grades can work better for complex undercuts and flexible demolding. Firmer grades can better support larger or more structured molds.

Choose by Viscosity

Low viscosity may help with detail penetration and bubble reduction. Medium viscosity may suit more controlled pouring environments.

Choose by Cure Speed

Fast cure can improve production speed. Longer working time may be more practical for larger or more complex molds.

FAQs

Is platinum cure always better than tin cure?

Not always. Platinum cure usually offers better performance in certain areas, but tin cure may still be the better fit for more cost-sensitive or general-purpose projects.

Can platinum cure be used for food molds?

Suitable grades may be considered depending on the application and required documentation. Always confirm before sampling or production.

What causes platinum cure failure?

Surface contamination, incompatible materials, and poor test practice are common reasons.
