Latest company case about Shenzhen Hanast New Material co.,LTD Certifications

This case study shows how artisan candle and soap producers serving Russia and Central Asia upgraded their moulds with HN-6XX Series tin-cure (condensation-cure) RTV-2 liquid silicone rubber from Shenzhen Hanast New Materials. The softer HN-610 and HN-615 grades deliver fine detail, clean release and no oil bleed—ideal for fragranced candles and decorative soaps.

Candle and soap moulds must capture delicate detail—petals, reliefs and fine textures—while releasing cleanly again and again. The producers needed:

• Fine pattern replication of intricate shapes;
• Clean, easy demoulding without tearing;
• No oil bleed that could blemish soap or candle surfaces;
• Room-temperature curing, with no ovens needed in a small workshop;
• Low cost per mould and a long shelf life.

HN-6XX is a two-component tin-cure RTV-2 silicone. Components A and B are mixed 100:2 by weight and cure at room temperature into a high-performance elastomer, offering ten hardness grades from Shore A 5 to 50.

For candle and soap work the producers selected HN-610 and HN-615: soft enough for easy release, firm enough to hold crisp detail over many cycles.

1. Pre-mix: shake the curing agent (Component B) well; stir Component A if filler has settled.
2. Weighing: weigh A and B in a 100:2 ratio by weight (e.g., 100 g silicone + 2–3 g curing agent).
3. Mixing: mix thoroughly, scraping the wall and bottom to fully disperse the curing agent.
4. Degassing: degas under vacuum for no more than 10 minutes.
5. Pouring: pour over the master pattern within the 30–40 min pot life, avoiding trapped air.
6. Curing: cure at room temperature for 12–24 h; leave 24 h before first use. Do not heat.

• Fine candle and soap detail reproduced faithfully from the master;
• Clean, easy demoulding with no oil bleed marking the products;
• Multiple demoulding cycles extended mould service life;
• Room-temperature cure kept setup simple and low-cost;
• ≤0.3% shrinkage kept mould dimensions stable across batches.

For candle and soap makers in Russia and Central Asia, HN-6XX tin-cure liquid silicone rubber offers detailed reproduction, effortless release and dependable room-temperature curing at an economical cost.
