Storage Instructions: Store in a dry environment at room temperature below 25°C. Keep the container tightly closed after each use to prevent moisture absorption, which accelerates setting time and reduces compressive strength . Use within 6 months of opening for optimal results.
BMS Gypsum Type III Yellow is a high-quality hard dental stone specifically formulated for the production of diagnostic models, working casts, orthodontic appliances, and prosthetic bases . This ISO 6873-certified Type III dental stone provides an optimal balance of compressive strength, abrasion resistance, and controlled setting expansion, ensuring accurate and durable models for a wide range of dental applications .
The Type III dental stone classification indicates a hard stone suitable for general dental models, orthodontic models, and prosthetic bases . The yellow pigment provides excellent contrast when working with wax, resin, and composite materials, reducing technician eye strain during model trimming, margin marking, and appliance fabrication. The bright yellow color also facilitates easy identification of Type III stone in the laboratory setting.
The optimized water-to-powder ratio of approximately 23-28ml per 100g powder produces a workable mix with smooth flow characteristics that capture fine impression details without air entrapment . Conventional mixing requires 60-90 seconds, while vacuum mixing can be completed in approximately 30 seconds . The setting time ranges from 10-14 minutes, depending on mixing technique and environmental conditions .
The set material achieves a compressive strength of ≥30 MPa (approximately 25 ± 2 MPa after 1 hour), providing sufficient hardness for model trimming, articulation, and orthodontic appliance fabrication without surface damage . Linear expansion is controlled at ≤0.15%, ensuring dimensional accuracy for reproducible study models and working casts . Available in a 25kg bulk bag, this Type III stone is ideal for high-volume dental laboratories, orthodontic practices, and educational institutions requiring consistent, reliable model material at an economical bulk price.
