1. Mixing of the two components

Mix Part A and Part B components according to recommended weight ratios.

Automatic mixing: The products should be used by means of automatic dosing equipment with a meter/static mixer because of the efficiency of degassing the material.

In order to avoid any air bubbles that may affect the mechanical properties, it is recommended to degas separately A and B part, after pouring it slowly and regularly into the tanks of the dosing machine. The A and B parts should be dosed and

mixed with a static mixer with standard commercial equipment (A special care is recommended in pumping the product from the tanks to avoid any air entry before dosing and mixing).

Hand mixing: If necessary, limited to control sample preparation products can be mixed by hand with special care (Recommendation is to use spatula, as A part has a high viscosity) in order to limit the inclusion of air in the mixture.

After mixing A and B parts, it is preferable to degas the product to eliminate the air bubbles that would be visible in the finished part and which would reduce the mechanical properties.

Degassing is generally carried out with a vacuum of 30 to 50 mbar releasing the vacuum several times during the operation. A recipient with a high diameter/height ratio is better suited to quick degassing; however the height must be sufficient to contain the swelling of the elastomer under vacuum conditions.

2. Cure inhibition

Certain materials that the BLUESIL RTV 150 LD A & RTV 147 B BLACK may be in contact with when curing could inhibit the reaction. Especially troublesome materials are: sulphur-containing cured natural and synthetic rubber compounds (neoprene, latex, SBR), tin catalyzed silicone rubbers, amine catalyzed epoxies, PVC stabilized with tin salts and some polyurethane elastomers.

When stored in their original unopened packaging at a temperature of between -5°C and +30°C,

  • BLUESIL RTV 150 LD A may be stored for up to 12 months,
  • BLUESIL 147 B BLACK may be stored for up to 18 months,

from their date of manufacture.

 

Comply with the storage instructions and expiry date marked on the packaging.

Beyond this date, Bluestar Silicones no longer guarantees that the products meet the sales specifications.

Store in a cool, dry place with adequate ventilation. Keep away from incompatible materials, open flames, and high temperatures. Store in tightly closed original container. equipped with a degassing device. Suitable containers: polyethylene. Steel drums coated with epoxy-resin.Please consult the Safety Data Sheet of this product.RoHS;VOC;WEEE
