Platinum Cure Silicone Rubber for Professional Mold Making

3. APPLICATIONS

BKSilicone® BK-A Series is designed for professional mold making and casting applications where softness, flexibility, and reliable demolding are required.
This series has been extensively used and validated in BKSilicone’s own factory production.

Typical applications include:

• Candle Molds
  Silicone molds for pillar candles, container candles, and decorative candle designs requiring clean surface finish and stable demolding.

• Concrete & Cement Molds
  Flexible molds for small concrete items, architectural details, and decorative cement components.

• Fondant & Cake Decorating Molds
  Molds for sugar paste, fondant, and cake decoration elements where fine detail reproduction and flexibility are required.
  Food-contact compliance should be verified according to local regulations.

• Plaster & Aroma Stone Molds
  Casting molds for gypsum, plaster, and aroma stone products with repeated production cycles.

• Creative & Character Molds
  Silicone molds for figurines, decorative objects, and custom creative designs with complex geometries.

• Soap Molds
  Flexible molds suitable for cold-process and melt-and-pour soap applications.

• Lightweight (Material-Saving) Mold Designs
  Thin-wall and reduced-material molds optimized for cost efficiency while maintaining structural stability and service life.

4. PROCESSING NOTES

1. Batch Consistency
   Always use Part A and Part B from the same production batch.
   If components from different batches must be mixed, conduct a small-scale test to verify curing performance and compatibility before full production.

2. Compatibility Testing
   A preliminary test is strongly recommended to confirm compatibility with specific substrates, mold materials, or additives prior to large-scale production.

3. Mixing & Curing Conditions
   For optimal performance, mix and cure the material at an ambient temperature of 20–30 °C (68–86 °F) with relative humidity below 50%.

4. Minimum Application Temperature
   Do not process below 15 °C (60 °F).
   Lower temperatures may significantly slow curing or result in incomplete crosslinking.

⚠️ CURE INHIBITION WARNING

Platinum-cure silicone systems are sensitive to certain contaminants.
Ensure all tools, containers, and model surfaces are clean and free from inhibitors.

Avoid contact with materials containing:

• Sulfur (e.g., sulfur-based clays, latex gloves)

• Tin compounds (condensation-cure silicone rubbers)

• Amines (certain epoxy systems and curing agents)

• Unsealed LCD / DLP 3D printed resins

Contact with these materials may result in surface tackiness or incomplete curing.

A small test cure is recommended whenever working with unfamiliar materials or substrates.
