Product data sheet
SioxX®
Designed for microsilica-containing LCC and ULCC, based on Al2O3 - SiO2 system with quick wet-out and low water demand.
SioxX®-Quick
Designed to act as an accelerator in undispersed aluminosilicate systems like dry gunning LCC and ULCC mixes without clay.
SioxX®-Zero
Designed for microsilica-gel bonded systems (NCC) to control the working and demoulding time and to develop high green-strength at room temperature.
SioxX®-Flow
Designed to work as a multi-functional microsilica dispersant, for aluminosilicate LCC, ULCC and NCC, giving customers freedom to fine-tune their products with other additives (accelerators, retarders, etc.). It enhances the rheological properties, reduces the water demand and increases the flow. Suitable also for shotcreting.
By combining both SioxX®-Flow and SioxX®-Set products, setting can be controlled. SioxX®-Flow product will also work in combination with Silica-Sol (colloidal silica) in NCC to control flow, working and setting time.When used in silica-sol systems a separate gelling agent needs to be added.
SioxX®-Set
Designed for undispersed systems mainly for NC gunning mixes. Can also be used for LC and ULC gunning. In castables and shotcrete (dispersed systems) SioxX®-Set can be used as accelerating agent.
SioxX®-Ten / SioxX®-Ten PLUS
SioxX®- Ten and SioxX®- Ten PLUS are primarily designed for ultra low cement alumina-based or microsilica-gel bonded no-cement castables.
SioxX®- Ten mainly works at the range of 800-1100ºC, while SioxX®- Ten PLUS is recommended to work at the range of 600-900ºC.
Both of them enhance the rheological properties, reduce the water demand, increase the flow, control the working and de-moulding time, help develop high green strength as well as high strength at the indicated working range of temperature.
SioxX® Mag
Designed for basic (MgO-based) refractory castables, to help avoid inherent problems of crack formation and poor workability. For advice how to best use our Specialties, contact our competent technical staff.
BOCAREPS™ (Boron carbide)
Boron carbide (B4C) is a dark grey–black material comprising 76.5–78 wt% boron, with an exceptional hardness that is only exceeded by diamond and cubic boron nitride.
Fusireps™ FS-99
Fused silica FS-99 is obtained by melting a high purity form of silica by electrical fusion and cooling the melt sufficiently fast to avoid crystallization (amorphous Silica). Afterwards it is classified in different grades.
