{"product_id":"steinteppich","title":"Silibond S-990 binder for stone carpets","description":"\u003cp\u003eSILIBOND-990 is a pre-polymerized, reactive urethane resin with low viscosity. The product is a ready-to-use binder for dry sands and grit. The resin is completely lightfast, making it perfect as a binder for pure white sands made of marble, granite, and similar light-colored aggregates!\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eFast and reliable curing\u003c\/li\u003e\n\n\u003cli\u003eHigh strength, similar to epoxy resins\u003c\/li\u003e\n\n\u003cli\u003eSolvent-free\u003c\/li\u003e\n\n\u003cli\u003eNo yellowing, even under intense sunlight\u003c\/li\u003e\n\n\u003cli\u003ePre-formulated, easy to use\u003c\/li\u003e\n\n\u003cli\u003eLow viscosity, easy to mix, and non-sticky\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\u003cp\u003eSILIBOND S-990 is an ideal binder for water-permeable, highly decorative joint mortars made from coarse sands, as well as for decorative stone carpets made of marble, granite granulates, or colored quartz.\u003c\/p\u003e\n\u003cp\u003eSILIBOND-990 cures through reaction with the moisture naturally present in the air.\u003c\/p\u003e\n\u003cp\u003eThe mineral aggregates used must be dry. For water-permeable mortars (drainage mortars), the aggregates should not contain any fine dust and should be sufficiently coarse.\u003c\/p\u003e\n\u003cp\u003eThe binder requirement for water-permeable joint mortars or sand carpets is low. It depends on the particle size distribution and grain shape of the aggregates and the desired strength. For a typical high-strength drainage mortar, sands with grain sizes between 0.2 and 0.7 mm are recommended.\u003c\/p\u003e\n\u003cp\u003eAn ideal ratio is 3 to 5% S-990 binder to 100 parts aggregate, depending on the grain distribution (and thus the surface area) of the aggregates. A binder content that is too high can lead to curing issues and even cause blistering, while a binder content that is too low will inevitably reduce the mechanical strength of the cured mortar.\u003c\/p\u003e\n\u003cp\u003eTo prepare the mortar, the binder is mixed homogeneously with the aggregates. It is advisable to use forced-action mixers. Conventional free-fall mixers for cement mortar are not suitable. The mixing time itself is short but depends on the performance of the mixer used. Ready-to-use mixtures are only slightly damp. They are installed immediately, are not sticky, and are easy to level, smooth, and compact. Mortars made from SILIBOND S-990 can also be installed at low temperatures. Compared to epoxy resin mortars, they still cure perfectly under these conditions, which are typically difficult for reactive resins.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCuring time\u003c\/strong\u003e (in mm thickness)\u003cbr\u003e23°C 15°C 10°C 5°C\u003cbr\u003e8 hours 11 9 6 3\u003cbr\u003e24 hours 25 18 12 8\u003cbr\u003e2 days 40 35 30 20\u003cbr\u003e2 \/3\u003cbr\u003e\u003cstrong\u003eProperties:\u003c\/strong\u003e Composition urethane polymer with NCO groups\u003cbr\u003e\u003cstrong\u003eForm of delivery: \u003c\/strong\u003eLiquid, ready-to-use\u003cbr\u003e\u003cstrong\u003eColor:\u003c\/strong\u003e Colorless, water-clear\u003cbr\u003e\u003cstrong\u003eOdor:\u003c\/strong\u003e Mild, characteristic of the product\u003cbr\u003e\u003cstrong\u003eViscosity:\u003c\/strong\u003e at 20° approx. 800 - 900 mPa.s\u003cbr\u003e\u003cstrong\u003eDensity:\u003c\/strong\u003e at 20° approx. 1.10 - 1.14 g\/ml\u003cbr\u003e\u003cbr\u003eMechanical properties (DIN 1164)\u003cbr\u003e- Mortar made of 100 parts by weight quartz sand 0.2 - 0.7 mm + 5 parts by weight SILIBOND 990 -\u003cbr\u003eCompressive strength approx. 40 N\/mm2\u003cbr\u003eFlexural strength approx. 20 N\/mm2\u003cbr\u003eModulus of elasticity\/flexural test approx. 8000 N\/mm2\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eSILIBOND S-990 is not flammable, but it is combustible.
