SILIRESIN Biothan® 1750 – Tough, crystal-clear casting and coating resin with over 55% renewable raw materials
Biothan® 1750 is an innovative casting and coating resin based on over 55% renewable raw materials. In combination with the hardeners Biodur® M 330 or Biodur® M330/395 creates a high-performance system that stands out thanks to its Toughness, water resistance, and excellent UV stability distinguishes.
Thanks to its special formulation, Biothan® 1750 is completely label-free, toxicologically harmless, and can also be processed in damp environments or underwater. With its crystal-clear appearance and high tear resistance, it is ideal for thin-layer encapsulation of LEDs, transparent coatings, or as an electrical casting resin and adhesive.
The system offers an excellent ratio of processing time to demolding time and allows precise adjustment of hardness by varying the mixing ratio. This makes it the ideal choice for demanding applications in the electrical and electronics industry.
