- Application Details
- To impart water repellency to glass wool or rock wool, SILRES® BS 1042 can be mixed with the phenolic resin solution or other additives. As the stability of the obtained mixtures greatly depends on the composition of the phenolic resin or the additives, no general comments can be made on compatibility.
- With suitable equipment, SILRES® BS 1042 can either be applied at the same time as or shortly before application of the binder.
- Treatment of glass wool mat or rock wool mat with SILRES® BS 1042 after drying and hardening is not recommended.
- SILRES® BS 1042 is applied by spraying. For this purpose it can be diluted with any quantity of water. The usual amount of SILRES® BS 1042 applied ranges between 0.2 and 2% based on the weight of material to be treated.
- The quantity of SILRES® BS 1042 to be applied 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 quantity. Excess SILRES® BS 1042 will cause a significant deterioration of the water repellent effect in perlite or similar materials.
- To impart water repellency to perlite or similarly porous materials, SILRES® BS 1042 is applied by spraying as well. It can be sprayed onto the warm material in order to avoid an additional drying process. Prolonged heating of the siliconized material must however be avoided.
- Guide formulation for laboratory tests to make perlite water-repellent:
- Mix 0,80g SILRES® BS 1042 with 400g of deionized water. Thoroughly mix or spray 200g of perlite with this impregnating solution in a mixer until the liquid has been completely absorbed. Fill the moist material into a large dish and dry in a drying oven at 50°C for seven days.
- Fill the impregnated perlite into fine-meshed nylon sacks and immerse in deionized water. The sacks must be covered by 5cm of water.
- Weigh the samples at fixed intervals. The results show that the perlite absorbs about 5% of its dry weight in water after one day. Untreated perlite absorbs far more than 100% of its dry weight in water in the same period. The test for water repellency according to ASTM 303-77 is recommended.

Storage & Handling
- Storage Information
SILRES® BS 1042 must be stored in the tightly closed original container. 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.
