One:Two-component platinum sulfur curing agent MC-98ABA two-component platinum-curing silicone vulcanizing agent, primarily used for low-temperature vulcanization and odorless silicone products. Such as extruded silicone tubes, profiles, and other non-standard shapes.LEDLED strips, silicone calendered rolls, silicone wires, etc. Products vulcanized with Miton platinum vulcanizing agent. One-shot sulfur curing can pass the FDA,ROHSCertification, two-stage vulcanization availableLFGBCertification.
Two: Advantages and Features of MC-98AB Platinum Sulfurizing Agent (Two-Component)
1. One-time vulcanization: environmentally friendly, odorless, and does not produce any new low molecular weight substances.
2. High hygiene level, capable of passing various existing certification standards such as:FDA、ROHS、LFGBPlease wait.
3. Enhances the tensile strength, tear resistance, and resilience of silicone products. The products achieve high transparency without yellowing.
4. Mayteng Company introduces advanced overseas production equipment and technology, produces independently, and offers more competitive pricing.
5. This platinum sulfurizing agent features high content, low dosage, low production cost, and an even more pronounced price advantage.
Three: Mixing ratio for two-component platinum sulfur curing agent MC-98AB:
MC-98A Addition Amount: 0.3%
MC-98B Addition Amount:0.4-1.0%（BFormula dosage varies greatly; please refer to actual usage (quantity).
Four: Sulfur temperature for two-component platinum sulfide curing agent MC-98AB
Silicone Extrusion Molding Box Temperature500About 20℃; Sulfurization Box Temperature200~380℃。
2. Silicone Calendering Vulcanization Oven Temperature130~180℃ or so. (The sulfur content needs to be set differently according to the size and thickness of the customer's product.)Please specify the desired temperature; customers may set it as preferred.
Five: Rubber Mixing Instructions: For example, with 20kg of raw material.MC-25AAgent0.3% × 20kgRubber Compound=60KilogramAAgent.
MC-25B Agent0.4% × 20kgRubber Material=80KilogramBAgent). First, please80CentsBAgent added20kgPre-mixed and uniformly compounded rubber material60C重庆AOnce the compound is uniformly mixed, it is ready for the vulcanization molding operation.ABPre-mixed raw materials should be stored at a temperature not exceeding25℃ Within the space, and it is required that4~ 8 Use within hours to prevent room temperature curing. There may be variations in the placement time of the specially formulated platinum sulfur curing agent blended raw materials; please refer to the actual time.

Eight: Two-component platinum sulfur curative MC-98AB Shelf Life: 6 months25 Degrees Fahrenheit (°F)
Item 9: Precautions for using two-component platinum sulfiding agent MC-98AB
1. Use platinum sulfiding; when encountering products like acetylene carbon black, deep green, deep red, and other dark colors, the ratio needs to be readjusted.
2Platinum sulfiding is used, and no materials containing... may be added to the raw materials.N . P. S The presence of atomic or heavy metal components (e.g., hydrogen sulfide, thiole) can cause the product surface to develop a large number of needle-like voids, and may lead to incomplete vulcanization of the product and sticking to the mold.
3. Keep the temperature during the rubber curing process moderate., SuggestNo more than40℃,Recommend using ice water recirculating cooling for the open mill.. Exceptional effectiveness.
4. Packed with PlatinumA、B After Treatment, The item needs to be placed where the temperature does not exceed25Within a space of ℃, and must be in4Hour(s)8HourUsed within, to prevent cross-linking at room temperature. If needed to extend Shelf Life,Increase the retardant as needed; additional purchase required.(Available for sale at our company).
Avoid high temperatures and direct sunlight, keep away from fire sources, acidic substances, metal oxides, ammonia compounds, and flammable materials.Yi for25Store below degree.
