When customers add color paste to liquid silicone themselves, they must pay attention to the following key points to ensure the final product meets quality standards:

1. Compatibility
· Use specialized color paste: Only use color paste specifically designed for platinum-cured liquid silicone. Using incompatible colorants (like those for tin-cured systems or other materials) can inhibit the curing process, resulting in the silicone remaining sticky or not solidifying at all.
2. Ratio Control
· Strict proportion: The amount of color paste added is typically very small, usually between 0.1% and 3% of the total weight of Part A.
· Avoid excessive use: Adding too much color paste can affect the physical properties of the silicone (such as tensile strength and tear resistance) and may also lead to uncured spots.
3. Even Dispersion
· Mix thoroughly: Color paste must be fully and evenly stirred into Part A. If the paste is not well dispersed, it can cause color streaks, spots, or uneven shades in the finished product.
· Scraping the sides: Remember to scrape the bottom and walls of the container during mixing to ensure complete integration.
4. Color Consistency
· Batch-to-batch variation: It is often difficult to get the exact same shade twice. It is highly recommended to mix enough material for the entire project at one time.
· Record keeping: If precise color matching is needed, customers should record the exact ratio (e.g., grams of color paste per 100g of silicone) for future reference.
5. Test Before Mass Production
· Small batch test: Always perform a small test before scaling up. This confirms the color accuracy and verifies that the color paste does not interfere with the curing reaction.
6. Cleanliness
· Prevent contamination: Ensure that mixing containers, stirrers, and the working environment are clean. Contaminants like dust, oil, or sulfur can ruin the silicone's performance.

If customers need to match a specific standard color (like Pantone), it is often safer to ask the silicone manufacturer to pre-color the material, as they can ensure perfect dispersion and curing stability.

How to use vacuum pump to release the bubbles?
1. Sealing and Start-up: Cover the vacuum chamber and ensure a tight seal. Start the vacuum pump.
2. Key Observations:
• As the pressure decreases, you will see the silica gel level gradually rise, with numerous bubbles forming and rapidly expanding. Sometimes the surface may appear to boil.
• This is the process of bubbles expanding, merging, and rising, which is normal.
3. Control and Maintenance:
• When the bubbles reach their maximum size and begin to burst, carefully observe the surface to prevent overflow.
• When the surface stops churning violently and most bubbles have burst and disappeared, start timing. The time to maintain the vacuum depends on the viscosity and quantity of the silica gel.
• General Recommendation: 2-3 minutes for low-viscosity silica gel; 5-10 minutes or longer may be required for high-viscosity or large quantities of silica gel.
4. Slow Degassing:
• A crucial step! After degassing, do not immediately and quickly open the air inlet valve. • The air inlet valve should be opened or the vacuum released very slowly, allowing outside air to gradually enter the vacuum chamber. If air enters too quickly, the external airflow will violently impact the silicone surface, instantly creating new, denser small bubbles, ruining the entire process.
Common Problems and Solutions
• Bubbles are always present?
• Check if the vacuum level is sufficient (does the vacuum gauge reading meet the standard)
• Check if the vacuum period is too short.
• Check if the "vacuum breaking" step is too fast or too forceful (this is the most common cause).
What if I don't have a vacuum machine?
1. You can ask the supplier to extend the curing time, allowing the silicone to naturally expel bubbles. You can gently run a toothpick across the surface during the process.
2. After pouring the silicone into the mold, you can place it in a refrigerator to extend the curing time, allowing the silicone to naturally expel bubbles.

Why customer like choose blue silicone ?
1. Visual Symbolism of Quality and Purity (The Most Important Reason)
• "Medical Grade" or "Food Grade" Association: In medical and food contact applications, high-quality silicone rubber is often colored (especially blue or purple) to distinguish it from ordinary industrial materials. Blue immediately conveys the message of cleanliness, safety, sterility, and high purity.
2. Key Function in Production and Processing
• Indicator of Mixing Uniformity: LSR is usually a two-component mixture (A and B adhesives) mixed in a 1:1 ratio and then cured. If one component is dyed blue and the other remains transparent or white, workers or machines can judge whether the mixing is sufficient by observing whether the color is uniform. Uneven color means incomplete mixing, which will lead to poor curing and defects in the product. This is an extremely important visual tool for quality control.
4. Industry Practices and Customer Psychology
• Establishing Industry Standards: In certain niche markets (such as high-end kitchenware and medical device seals), blue silicone has become a "default" or "preferred" standard. Customers choose blue because it represents industry-recognized reliable quality.
• Psychological Security: For end consumers, especially parents buying baby products and food preparation tools, seeing a pure blue silicone product provides a stronger sense of security and trust than seeing a transparent or potentially discolored product.
So which silicone color you almost choose ?
