أخبار الشركة الأخيرة عن Platinum vs. Tin Silicone: Which RTV-2 is Best for Casting Gypsum and Cement Wall Tiles?

When choosing a two-component RTV-2 silicone for casting architectural decor, manufacturers often face a dilemma: choose a cost-effective condensation system (tin-cure) or a high-performance addition system (platinum-cure)?

Tin-Cure Silicones (Condensation System)

This is the traditional, reliable choice for most workshops producing gypsum stone.

  • Advantages: Cost-effective and forgiving to work with in standard workshop environments.

  • Characteristics: Exhibits minor shrinkage over time (approx. 0.2–0.5%), with a mold lifespan of several hundred pours when using proper release agents.

Platinum-Cure Silicones (Addition System)

The professional choice for industrial factories producing millions of square meters of facade tiles.

  • Advantages: Virtually zero shrinkage (<0.1%), high chemical resistance to aggressive concrete and polymer mixes, and a mold lifespan that is 2–3 times longer.

  • Application: Ideal if your facility specializes in heavy cement-based pavers and architectural facade stones.
