ISTRA 40 is a normal setting, rapid hardening Cal-cium Aluminate Cement (CAC) with high early strength. It differs substantially from the usual calci-um silicate cements (Portland cements) in its manufacturing process, chemical composition and rapid strength gain. ISTRA 40 is composed of calcium aluminates with the following characteristics: • high early strength • refractoriness • high abrasion resistance • resistance to biogenic sulphuric acid corrosion (BSAC)

ADI-CON CW PLUS is a dry, free-flowing powder containing a blend of inorganic and organic chemicals, a small amount of sand, and silica-based materials. The reactive materials react with lime generated by the hydration reaction of cement and plug the capillary porosity, making concrete watertight under water-head pressure.

WALOCEL™ J75M S hydroxypropyl methyl cellulose was developed for use in tape joint compounds, tile adhesives and other ready-mix dispersion systems. A cold water dispersible cellulose ether, WALOCEL™ J75M S is a high viscosity thickener that has been surface treated to delay solubility, making it easily dispersible in aqueous systems. It develops viscosity as pH is increased, and its distinct molecular structure resists bacterial degradation, helping to increase shelf life of materials formulated with this additive.

CMP™ COLOURED ANTI-SKID AGGREGATES is produced with European technology and production process. It has special advantage in life time, colour and safety for road construction and maintenance. The aggregates is made by calcinating hard minerals with pigment at high temperature and then crushed into designed sizes and coated with a hard layer of colour film. Applied with high strength epoxy resin system, it can make the abrasion value of road surface to 70 up. It improves road safety by reducing braking distance by 30%-40%. Its vivid colour is good traffic separation and management as well as beautiful decoration. Because of its double colouring system, the colour of aggregates can last long – after the coating film is worn out, the inside aggregates is still colourful. CMP™ COLOURED ANTI-SKID AGGREGATES is convenient and easy in application.
