SILPURAN® Silicone Adhesive Gels – Penetration Test

The 2-component RTV-2 system is mixed 1:1. Proper mixing of the two components followed by degassing is essential. SILPURAN® silicone adhesive gel is prepared for curing. To assure proper curing and hence reproducible results, the material is cured for 60 minutes at 120°C. The penetration test method determines the softness of the SILPURAN® gels. A cone with a defined weight is positioned on the surface of the cured gel specimen. The cone is allowed to sink into the material. The depth it reaches after a given time determines the hardness of the gel.
