FAQ

1. Q: What is the mix ratio and cure time of this food grade silicone?

A: Mix Component A and Component B at a 1:1 ratio by weight. Pot life is 30-40 minutes at 25°C. It cures in 3-4 hours at room temperature, or in 20 minutes or less at 80-100°C for fast production.

2. Q: Is this silicone food grade and safe for food contact molds?

A: Yes. The HN-E620 is a food-grade platinum-cure (addition) silicone compliant with FDA 21 CFR 177.2600 and LFGB, and certified with MSDS and RoHS. It is non-toxic, odourless and releases no low-molecule by-products during cure, making it suitable for gummy, jelly, candy, chocolate and baking molds.

3. Q: Which molds is the 20 Shore A grade best for?

A: The 20 Shore A (HN-E620) soft-medium grade is ideal for gummy, jelly, candy, chocolate, baking, soap and candle molds and other high-detail food-contact molds. Softer grades (5-15 Shore A) suit delicate work, while harder grades (35-50 Shore A) suit rigid molds and high-wear parts.

4. Q: What must I avoid to prevent platinum catalyst poisoning?

A: Platinum-cure silicone may fail to cure in contact with organotin compounds, sulfur / polysulfide, amines, polyurethane, phosphorus compounds, organic acids and solder flux. Keep all substrates, tools and containers clean, and never mix with tin-cure silicone residues.

5. Q: What are the MOQ, supply ability and delivery time?

A: MOQ starts at 20 kg. Supply ability is 50 tons per month, with about 3-5 days lead time for samples and 10-15 days for bulk orders. Components A and B are packed in 10/20/25 kg iron or plastic drums, or as 20/40/50 kg kit sets.
