In footwear manufacturing, precision matters at every stage. From mold design to sole bonding, each step in the process directly affects product quality, line efficiency, and production cost. Yet one of the most overlooked variables on the production floor remains the release agent.
Release agents are applied to molds before every cycle to prevent materials from bonding to the mold surface. When they work well, they go unnoticed. When they do not, the consequences are immediate: parts that stick, molds that require frequent cleaning, residue that interferes with adhesion, and scrap rates that quietly eat into margins.
In the footwear industry specifically, mold release performance is critical. Improper application or poor-performing release agents can cause reduced productivity, higher scrap rates, or even failure of the part to release from the mold entirely. In direct-attach sole processes, the stakes are even higher if the sole does not release properly, both the sole and the upper are wasted together.
Introducing Kezal Water-Based Release Agent
Kezal Water-Based Release Agent is a silicone-free, high-performance release solution, with zero VOC and non-flammable properties, developed for the demands of footwear and industrial manufacturing. It is designed to deliver clean, consistent release performance while overcoming the limitations traditionally associated with water-based systems.
Its formulation creates a uniform, high-performance thin film across the mold surface ensuring seamless part separation without oily transfer, surface contamination, or mold buildup. The result is a cleaner mold, a cleaner part, and a faster production cycle.
What Kezal Delivers on the Production Line
1. Silicone-Free Formula: Better Bonding, No Post-Clean Needed
Because Kezal contains no silicone, there is no risk of oily transfer contaminating part surfaces after demolding. This is especially important in footwear production, where midsole-to-outsole bonding integrity is non-negotiable. Silicone residue is well-documented to interfere with adhesion processes, in some cases causing manufacturers to build additional cleaning steps before bonding, adding time, labor, and cost to every production cycle.
With Kezal, those extra steps are eliminated. Parts come out of the mold clean and ready for the next stage of production.
2. Consistent Release Performance: Fewer Defects, Lower Scrap
Inconsistent release is one of the most common and costly problems in mold-based manufacturing. Uneven film formation leads to parts sticking in localized areas, causing surface defects, torn parts, and production stoppages for unplanned mold cleaning.
Kezal is formulated for reliable, uniform film coverage across the mold surface delivers consistent release results from cycle to cycle, shift to shift. This directly reduces scrap rates and the downtime associated with mold maintenance.
3. Up to 33% Lower Consumption: Measurable Cost Savings
One of the most significant advantages of Kezal is its consumption efficiency. Our internal testing shows that switching to Kezal can reduce release agent usage by up to 33% compared to other water-based products. This is a direct, bottom-line impact.
In high volume footwear production, where release agents are applied continuously across multiple lines and shifts, a reduction of this scale translates to meaningful savings on product cost, storage, and handling without any compromise on performance.
4. Non-Flammable, Zero VOCs: Safer Workplace, Simpler Compliance
Kezal's water-based formulation is non-flammable and contains zero volatile organic compounds (VOCs). This removes fire hazard risks from the production environment and significantly reduces chemical vapor exposure for operators, which is a persistent concern in enclosed production facilities.
From a regulatory standpoint, zero VOC water-based products are less expensive to ship, easier to store, and require fewer safety protocols than alternatives with higher chemical content. This simplifies compliance and reduces the administrative burden on operations teams.
5. Customizable Finish: Matte, Semi-Matte, Glossy, or Extra Glossy
Not all footwear products require the same surface finish. Kezal offers full flexibility in this area, allowing manufacturers to select the desired finish level from matte, semi-matte, glossy, or extra glossy, depending on the product specification and aesthetic requirement.
This means a single release agent solution can support multiple product lines and styles within the same facility, reducing the need to stock and manage different products for different finishes. It simplifies procurement, reduces inventory complexity, and gives production teams greater control over the final appearance of the molded part.
The Right Release Agent Does Not Ask You to Compromise
Early water-based release agents earned their reputation for underperformance. Inconsistent release, poor film formation, and contamination issues led many manufacturers to settle for workarounds rather than solutions.
Kezal was built to change that. Its silicone-free formulation, consistent performance, zero-VOC safety profile, and proven consumption savings deliver tangible value where it matters on the production floor.
