1.Rehomogenising

Bluesil RTV 3825 tends to settle during storage, and must be rehomogenised before use. This should be done directly in the original container, either by hand with a spatula, or mechanically with a stirrer.


2.Degassing
Be taken to entrap carefully with little air when the catalyst is added, as it would cause bubbles in the finished product. It is therefore advisable to degas the mixture under a vacuum of 30 to 50 mbar in three to five minutes, applying the vacuum twice in the chamber. Degassing is quicker in a container with a high diameter: height ratio.

3.Cross linking
At 23°C RTV 3825 will cure in 15h. In order to achieve the best possible performance levels from the pads; it is preferable to wait for 72 h before using them.


 

No special storage precautions noted. Material is stable under normal conditions. Avoid contact with oxidizing agents. For further information, refer to Section 10: "Stability and Reactivity". Use container made of: Suitable plastic material.Please consult the Safety Data Sheet of this product.

BLUESIL RTV 3825

Bluesil RTV 3825 is a two component silicone elastomer, crosslinking at room temperature by reaction of polycondensation. It yields a soft flexible, elastic material presenting excellent tear resistance.

2 Part RTV

Fluid

For making moulds and reproduction of objects of complex form with deep undercuts by either brush or casting method.

  • Very good chemical resistance, superior resistance to polyester (PES) resin with high number of reproductions
  • Medium viscosity and good flowability
  • Fast curing
  • High tear strength and medium hardness
  • Good elongation for easy demoulding
