Whether you are operating a continuous press system, a day-light press, or another type
of wood pressing or finishing operation, there are many variables that affect the quality of your end product and the efficiency of your operation. Most of the products we have developed for this industry are water-based, and all have been tailored to work within a process that is demanding in terms of both chemical, thermal and mechanical attack of the pressing surface.
Chem-Trend has formulated release agents to get to the heart of the issue of pMDI
resin systems. The actual causes of sticking/buildup have been intensively studied by
Chem-Trend chemists, which allowed us to develop products that eliminate the
fundamental problem. With our release agents, buildup cannot gain a foothold on
the pressing surface, ensuring that the manufacturing plant can remain in operation for
extended periods of time. Since the release property of these products leads to a pressed
article surface that is very smooth and consistent in texture, surface sanding — where
necessary — is minimized.
We work with the full gamut of products, including:
- Medium Density Fiberboard (MDF)
- Oriented Strandboard (OSB)
- Door panels
The wood composite/panel pressing industry tends to be one that makes huge volumes of products on an almost continuous basis, and Chem-Trend has formulated its products to work in that type of demanding environment. Our products are easy to work with and remain highly stable under processing conditions of both heat and cold. With extensive research and development facilities around the world, we work alongside customers to find custom solutions that work with exacting regulations, varying raw materials, and your unique facilities.

Continuous wood-pressing process is a widely applied technology whether you use PMDI or UF/Phenolic binder.
For PMDI binder use, release and production efficiency is critical.
For UF binder, an optimal belt cleanliness will ensure a high-surface-quality board.
In these situations, it is vital to properly wet the belt to ensure optimal surface coverage by applying the release agent in the right amount. Chem-Trend’s close collaboration with major press producers and spray equipment companies ensures:
- Exceptionally effective release agents for your spraying equipment
- Reduced downtime by lowering spraying equipment maintenance time
- Custom solutions based on your process and wood type
- Optimum spray patterns
Particle board requires a unique approach to ensure exceptional and consistent results. Using internal release agents directly added to the PMDI binder, Chem-Trend’s solution opens possibilities for productivity and potential.
This provides several advantages:
- A simplified process, since no release agent needs to be applied on the mat or on the press
- Zero impact on the board’s properties, allowing for maximum quality
- A more consistent result
Mat spray and caul spray solutions require extremely specific and highly technical properties, such as non-diving and easy dispensing. Whether it’s MDF UF or a daylight process combined with PMDI, the complexity and situational needs require a sophisticated and experienced partner.
Chem-Trend helps work alongside customers to ensure an ideal solution, no matter if you produce OSD, MDF, or particle board.
Our solutions give you:
- Exceptional sprayability
- Versatility for different wood types
- Adaptability to work with varying press capacities and dimensions
- Dilution equipment and monitoring for consistency and confidence
When working with daylight press, the process is critical to manufacturing success.
Chem-Trend’s semi-permanent release systems come in liquid form, designed to cross-link with humidity or heat and chemically bond to the mold. This provides an inert, durable polymeric film that is resistant to wear as well as chemical and thermal attack.
Because of the cross-linking nature of the semi-permanent solution, it enables a reduced maintenance schedule of the press plattens, which helps:
- Improve production efficiency
- Enhance board quality
- Create more certainty and consistency
