Specialties for refractories
Products to further enhance properties of advanced refractories.
Our strategy is to develop specialty products and offer complementary products that will further advance the refractories technology and create value for our customers. These products include SioxX® Specialties, EMSIL-DRY® and AloxX™-Spheres.
SioxX® Specialties: A "treasure chest" for refractory technologists
Our portfolio of performance enhancers for advanced refractory products are offered under the brand name SioxX®. Based on global leadership in microsilica technology and a strong focus on R&D in refractory castables, new products are continuously developed and offered the industry.
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.
Product data sheet & Safety information
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.
EMSIL-DRY®: Removes dilatancy, shortens wet-out and improves the bond phase
Special burn-out polymer fibres for refractory castables to speed up drying and reduce the risk of spalling and explosion during heat-up.
