RS-620 Anti-Tack Agent – Product Composition Table

Material Name	Chemical Identifier	Percentage (by wt)
Stearic Acid	—	12～20%
Emulsifier X-1	—	0.5～1%
Emulsifier X-2	—	0.5～1%
Emulsifying Thickener	—	0.1%
Water	7732-18-5	80～88%

1. Stearic Acid is the primary active agent, commonly used for its anti-tack and release properties.
2. Emulsifiers and thickeners are included to stabilize the emulsion system, ensuring good dispersion and coating stability even after dilution.

Compatible Rubber Types｜Application Scope of RS-620

RS-620 is a water-based anti-tack agent designed for a wide range of uncured rubber materials, including both natural and synthetic rubber compounds. It delivers stable performance particularly in the stacking and handling of rubber in sheet, strip, or block form. Typical compatible materials include:

• Natural Rubber (NR)
• Styrene-Butadiene Rubber (SBR)
• Ethylene Propylene Diene Monomer (EPDM)
• Nitrile Butadiene Rubber (NBR)
• Other uncured rubber compounds and elastomer formulations

This product is also suitable for early-stage rubber processing such as post-mixing storage, intra-plant transport, molding queue holding, and automated feeding systems, helping reduce risks of material sticking, deformation, and equipment contamination.

Operational Scenarios and Processing Challenges for Anti-Tack Agents

Production Stage	Common Issue Description
Post-Mixing → Rubber Sheet Stacking	Rubber sheets stick together, making them difficult to separate. Operators must pull forcefully, causing material deformation or surface damage.
Temporary Storage & Handling	Rubber compounds stick during transport to the next process (e.g., calendering), disrupting feed flow and causing stacking misalignment or material tearing.
Pre-Molding or Pre-Curing Wait Time	During extended idle times, rubber adheres to molds or to itself, making mold insertion difficult and increasing mold contamination, requiring frequent cleaning.
Automated Mixing Lines or Robotic Handling	Stickiness interferes with automated feeding systems, leading to detection errors, jamming, or product misalignment.

Comparison Table of Anti-Tack Agent Types – Advantages and Limitations

Type	Form	Application Method	Advantages	Limitations
Water-Based Anti-Tack Agent	Clear or Milky Liquid	Diluted for brushing, spraying, rolling, or dipping	✅Eco-friendly, VOC-free ✅ Does not interfere with vulcanization ✅ Easy to clean	❌ Requires drying time ❌ Compatibility testing may be required for certain compounds (📩 Samples available upon request)
Powder-Type Anti-Tack Agent	White Powder (e.g., Talc)	Sprinkling or powder dusting	✅ Low cost ✅ Easy to apply	❌ May cause dust contamination ❌ May leave surface residue ❌ May interfere with vulcanization
Oil-Based Anti-Tack Agent	Viscous Liquid or Grease	Wiping with cloth or brushing	✅ Strong anti-tack performance ✅ Suitable for high-tack materials or heavy-pressure molding	❌ Contains organic solvents ❌ May cause equipment contamination ❌ Difficult to clean
Paste-Type Anti-Tack Agent	Thick Paste (White or Gray)	Manual application on molds or specific areas	✅ High adhesion, low flowability ✅ Allows targeted anti-tack application in specific areas	❌ May leave surface residue ❌ Some silicone-based products may interfere with subsequent bonding or coating processes
Release Agent Type	Liquid or Emulsion	Spraying onto molds or rubber surfaces	✅Dual function (release + anti-tack)） ✅ Suitable for molding processes	❌ Contains organic solvents May interfere with vulcanization
PE Film / Separation Film	Solid Sheet	Covering rubber surfaces	✅ Long-lasting and stable performance ✅ No chemical residues	❌ High cost ❌ Time-consuming to apply ❌ Not suitable for high-temperature dynamic processes

Application Scenarios and Benefits of Water-Based Anti-Tack Agents

RS-620, a water-based anti-tack agent, is ideal for production environments with higher standards for cleanliness, environmental compliance, and process stability. It is particularly suited for the following situations:

✅ Forms a Stable and Transparent Barrier Layer
Creates a uniform thin film on the rubber surface, preventing adhesion during stacking, handling, or molding while maintaining material cleanliness.

✅ Does Not Interfere with Vulcanization
No cleaning is required after application—downstream molding and curing can proceed directly, making it well-suited for continuous and time-sensitive automated production lines.

✅ Compatible with Automation and Mechanical Handling
Leaves no dust or oily residue, making it ideal for use with robotic arms, rollers, and rubber storage systems, reducing the risk of equipment contamination.

✅ Eco-Friendly and Operator-Safe
Free of organic solvents and unpleasant odors. Non-irritating to skin and respiratory systems, contributing to a safer and cleaner work environment.

✅ Flexible Application Methods to Suit On-Site Conditions
Can be applied via brushing, spraying, or rolling, allowing adaptable integration into manual or automated coating processes based on production needs.
