SILRES® BS 5133

$SILRES<sup>®</sup> BS 5133

SILRES® BS 5133 is an aqueous and waterdilutable emulsion of a reactive polydimethylsiloxane (PDMS). It is used to impart water repellency to thermal insulation materials made of glass or stone mineral wool bound with organic binder systems.

 


Eigenschaften

SILRES® BS 5133 has been developed and optimized to be compatible with binders based on carbohydrates.

 

After compatibility tests SILRES® BS 5133 is added to the binder mixture. The product is sprayed onto the mineral fibers as part of the binder mixture as usual directly at the fiberizing unit or via an additional spraying equipment applied separately. For this purpose SILRES® BS 5133 can be diluted with any quantity of water.

 

Based on the weight of the mineral fibers the addition ratio varies and can be up to 0.3 weight % even for stone mineral wool (always based on the weight of the dry final product) due to the hydrophilicity of the carbohydrate-based binders. The quantity of SILRES® BS 5133 to be applied also depends on the desired water repellency of the end product general recommendation cannot be given. Individual tests must always be conducted in order to define the necessary quantities.

 

Due to the variety of possible binder types used plus further specific additives, however, a specific compatibility test in each plant is necessary. As the shelf life of the various mixtures depends largely on the formulation e. g. on the dilution of the emulsion it is recommended to apply the binder mixture without delay.

Lagerung

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
