Optimal results through reliable materials

For the manufacture of silicone rubber articles and for industrial applications applied with a wide variety of systems such as silicone rubber, polyurethane, polyester, plastics and composites TERRA offers a versatile range based on the most innovative polymer and elastomer technologies. SILASTOSIL® series RTV silicone rubbers are used in many industries and in a  number of market segments such as art & foundry, footwear, furniture, polyurethane moulding, automotive, textile coating, moldmaking, medical, food, construction, electronic potting & encapsulation, pad printing, and many more...
SILASTOSIL® series RTV flowable and liquid silicone rubbers are formulated as one- or two-component silicone rubber sytems that vulcanize at room-temperature with tin or platinum catalysts. 
The platinum-catalyzed RTV silicone rubbers are food-grade and skin-contact, fulfill all conditions related to food grade status (FDA compliance), are therefore ideal for food and skin contact and medical applications. They guarantee high productivity with outstanding product performances, and care for bot, human health and environment:
SILASTOSIL® line RTV silicone rubbers have unique features and benefits:
- excellent flowability
- optimal viscosities for various application methods
- a wide variety of hardness alternatives ranging from 0 to 70 shore A
- hardness levels could be adjusted by adding silicone fluids 
- high potential of silicone fluid adding
- in general translucent or transparent colors
- black or high-transparent alternatives for electronic potting and encapsulation
- ideal for optoelectronic devices, LED's and assemblies, LED filling
- white or red alternatives for manufacturing of printing pads
- anti-yellowing
- easy to color with liquid colorants for silicone rubbers
- adjustable curing and operation times
- easy deaeration (degassing)
- excellent mechanical, chemical and electrical properties
- high heat and cold resistance
- excellent thermal stability and weatherability
- high tear strength
- high tensile strength
- high elongation rates
- very good impact absorption
- easy to use
- comply with FDA and RoHS, suitable for food related and medical
- cost-effective
TERRAFLUID® line silicone fluids are used to adjust the flowability and to reduce the hardness of the silicone rubbers. They are offered in a wide variety of viscosity ranging from 0.65cSt to 1.000.000cSt.
Holcosil® line liquid colorants for silicone rubbers produced by Holland Colours are food grade, comply with FDA and RoHS requirements fully, and ideal therefore for food and medical related applications.


TERRASIL® SILANE line silanes are used as performance enhancing additives to enhance the adhesion or mechanical performances of the silicone rubbers. They are highly effective and efficient solutions which guarantee optimal results.
