⚙️ Wacker vs CHT - Key Differences
Wacker: Mixing ratio 9:1 or 10:1, Shore A 17-31, food-safe options (RT 620), antistatic (RT 629), FDA-compliant.
CHT: Mixing ratio 1:1 (simpler), Shore A 12-40 (broader), platinum addition, antistatic (21006 and 21004), wide hardness range.
🎯 Choice guide
Food packaging: Wacker RT 620 (FDA-compliant, Shore A 17)
Electronic components: Wacker RT 629 or CHT 21006/21004 (antistatic)
Very fine details: CHT SilSo Print 21006 (Shore A 12, 1:1 mix)
Standard pad printing: Wacker RT 623 or CHT 21001
High volume: CHT SilSo Print 21004 (Shore A 40, abrasion resistance)
📋 Processing guidelines
⚠️Important: Only process components A and B with the same lot number together!
Surface: Clean and free of inhibitors (sulphur, plasticisers, urethanes, organometallics).
Mixing: Mix thoroughly in the recommended ratio. A mechanical mixer is recommended.
Bleeding: Vacuum 30-50 mbar, 5-10 minutes.
Curing: Room temperature 20-25°C, can be accelerated by heat.
Shore adjustment: Add silicone oil (5-30%) for lower hardness.
