Product Overview

Yinuo New Material Technology (Heze) Co., Ltd. presents YN-E660, a high-performance release agent specifically formulated for friction material products, including brake pads, brake linings, clutch facings, and other automotive and industrial friction components-. Developed with advanced high-temperature polymer technology, our water-based release agent delivers exceptional release performance, superior thermal stability, and outstanding surface finish quality for friction material parts.

Designed to meet the demanding requirements of friction material manufacturing processes – including hot pressing, molding, and curing operations – YN-E660 effectively prevents adhesion between the friction compound and the mold surface, ensures smooth part ejection, and significantly extends mold service life.

Key Features & Benefits

Superior Release & Lubrication Performance
YN-E660 contains high-temperature specialty polymer resins and advanced lubricating agents that provide exceptional release and lubrication properties-. It effectively prevents sticking and adhesion between the friction material compound and the mold, minimizing defects such as surface cracks, edge chipping, and uneven finishes.

High-Temperature Stability
Engineered to withstand the extreme temperatures encountered in friction material curing and molding processes (typically 150°C–200°C), YN-E660 maintains excellent wetting properties and forms a durable, uniform protective film on the mold surface even under prolonged thermal stress. This ensures consistent performance throughout extended production cycles.

Excellent Surface Finish
Friction products produced with YN-E660 feature clean, smooth, and defect-free surfaces – free from residue, staining, or surface imperfections. The superior finish quality enhances the appearance and performance of finished parts and facilitates subsequent bonding or coating operations.

Non-Interference with Post-Processing
YN-E660 does not interfere with downstream finishing operations. Friction components are easily cleaned and fully compatible with painting, coating, bonding, and printing processes – critical for applications such as brake pad shim attachment and noise-damping coating application.

Environmentally Friendly & Operator Safe
Formulated as a water-based, non-flammable, low-odor, and non-toxic product, YN-E660 contains no hazardous solvents or heavy metals and generates minimal smoke or harmful fumes during application. It complies with international environmental regulations, creating a safer, cleaner, and healthier working environment for your operators.

Cost-Effective & High Dilution Ratio
As a concentrated formulation, YN-E660 offers excellent dilution ratios – significantly reducing consumption costs while maintaining superior performance. Its high efficiency allows for minimal application quantities per cycle, further lowering overall production expenses.

Extended Mold Life
By providing effective lubrication and release, YN-E660 minimizes mold wear and abrasion, reducing maintenance frequency and extending tool life – delivering long-term cost savings for your production operations.

Applications

YN-E660 is widely used in the production of friction material products across various industries, including:

• Automotive brake pads and brake linings

• Commercial vehicle brake components

• Clutch facings and clutch plates

• Industrial friction components

• Railway brake blocks

• Motorcycle brake pads

It is suitable for both hot-pressing and cold-pressing molding processes, and compatible with a wide range of friction material formulations, including phenolic resin-based, rubber-based, and semi-metallic compounds.

Usage Instructions

• Dilute the concentrated YN-E660 with clean water at the recommended ratio (typically 1:20 to 1:50, depending on part complexity and molding conditions)

• Apply uniformly to the mold surface using spray or brush application methods

• Ensure complete coverage before each molding cycle

• Allow proper drying/curing before loading the friction material compound

• Store in a tightly sealed container at temperatures between 5°C and 35°C, away from direct sunlight
