Product Description

PRODUCT DESCRIPTION                                                                                              
 

Silway 760 is a very efficient aqueous water dilutable emulsion of a reactive polydimethylsiloxane. It is used to impart water repellency to glass wool (fiber glass) or stone wool bound with phenolic resin. It can also be used for expanded minerals such as perlite or vermiculite, or expanded clay aggregates.

TYPICAL APPLICATIONS                                                                                               

Silway 760 has been developed and optimized to be compatible with phenolic resin binders and tolerates without surplus of ammonia varying processing and formulating conditions. It is compatible and can be mixed with most phenolic resins, no side reactions or precipitations are observed. Based on the large variety of phenolic resins 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.

SPECIAL FEATURES                                                                                                      

*The viscosity was reduced, which significantly improves the feeding and dilution process.
*Once sprayed onto the substrate, in comparison to other emulsions of reactive polydimethylsiloxanes
Silway 760 shows an especially high thermal stability in the manufacturing process of the thermal insulating material.

USAGE                                                                                                                            

Silway 760 is applied after compatibility test with the phenolic resin mixture by mixing and spraying or via an additional spraying equipment applied separately - at the same time or shortly before application of the binder. For this purpose it can be diluted with any quantity of water. Based on the glass or stone fiber mass the addition ratio varies between 0,05 and 0,2 weight % for stone wool and 0,1 and 0,3 weight % (always based on the weight of the dried final product) for glass wool. The quantity of Silway 760 to be applied also depends on the desired water repellency of the end product; a general recommendation cannot be given. Individual tests must always be conducted in order to define the necessary quantities. To impart water repellency to expanded perlite or similar porous materials, Silway 760 is applied by spraying as well. 0,2 to 0,4 % by weight Silway 760 are recommended as a dosage rate for perlite, 0,1 to 0,2 % for expanded clay aggregates. It can be sprayed onto the warm expanded material in order to avoid an additional drying process. Prolonged heating of the siliconized material must however be avoided.
