Platinum Curd Liquid Silicone Rubber

Platinum-cured silicone (addition-cure silicone) is a two-part, platinum-catalyzed liquid silicone rubber that cures into a non-toxic, odorless, and highly transparent elastomer. It is ideal for food, baby care, electronics, and precision molding applications where safety and accuracy are critical.

Directions for Use:

Step	Instructions	Key Notes
1. Mixing Ratio	A (Base) : B (Platinum Catalyst) = 1:1 or 10:1 (by weight or volume)	Use an electronic scale for precision
2. Mixing	Stir thoroughly for 30–60 seconds until uniform color	Avoid circular stirring to minimize bubbles
3. Degassing	Vacuum degas for 1–3 minutes to remove air bubbles	Alternatively, rest for 5–10 minutes if no vacuum
4. Pouring/Brushing	Pour or brush into molds; can be cast, brushed, or sprayed	/
5. Curing	Initial cure in 30–60 min at 25°C, full cure in 2–4 hours	/

Primary Application：

Industry	Typical Uses
Food-Grade	Baby nipples, baking molds, spatulas, ice cube trays, seals
Baby Care	Pacifiers, teethers, breast pump parts
Electronics	LED strips, sensors, precision circuit encapsulation
Precision Molding	High-clarity crafts, diamond molds, microstructure replication

Usage Notes and Packaging:

Avoid contamination: Sulfur, phosphorus, nitrogen, amines, PVC, natural rubber, oils, or tin residues will cause "platinum inhibition".
Tool separation: Never use tools that have touched tin-cure silicone.
Environment: Work in a clean, dry area (humidity <60%, temperature 20–25°C).
Package：5kg can → 20kg white barrel → 25kg iron barrel
