Solutions for Continuous and Daylight Presses | UF and PMDI | OSB, MDF, and Particle Board
There’s No Room for Waste
Release agents are a complex yet critical part of manufacturing. And no two systems have exactly the same chemistry needs. Because whether you are operating a continuous or multi-opening press, there are many variables that affect both the efficiency of your operation and product quality.
At the end of the day, you need a release agent you can rely on to be a linchpin of your processes—you can’t afford to waste time or money on equipment shutdowns caused by sub-standard product.
Improvement is Always Possible
With different feedstock, different types of presses, different operating systems, each mill is unique. You need a specialty release agent to help you increase production rates and reduce defects, without causing buildups. Our reps use their industry knowledge to work closely with our research and redevelopment team to create, test, and perfect the customized solutions you need to get the job done.

Frequently Asked Questions About Wood Composite Release Agents
It forms a barrier between the resin-bonded mat and the steel so the panel releases cleanly without pre-cure sticking, and it keeps resin from building up on the belt, caul or platen. Done properly it protects panel surface quality and press availability at the same time.
Yes. PMDI bonds aggressively to steel and needs a more robust barrier than a UF system does. Running a UF-grade release agent on a PMDI line is one of the more common causes of build-up and unplanned belt cleaning, and it usually shows up as a gradual increase in cleaning frequency rather than a sudden failure.
Yes. A continuous press needs a film that survives sustained contact at line speed with continuous re-application. A multi-opening or daylight press has a cycle with dwell and a different thermal profile, so the film has to hold through the press cycle instead of being renewed constantly.
Usually application rather than product. Under-spray at the edges, worn or plugged nozzles, incorrect dilution, or a change in resin loading or mat moisture will all show up as build-up. Check spray pattern and actual applied rate per square metre before changing chemistry.
Yes, and it is the failure mode mills notice last. Carryover onto the panel face interferes with sanding, laminating, painting and overlay adhesion. If you are fielding adhesion complaints from a customer, the release agent belongs on the list of things to check.
Measure applied rate per square metre rather than drums per week, fix nozzle wear and spray pattern first, then step the rate down in small increments while watching for the first sign of pre-cure or build-up. Most mills find more headroom in application control than in unit price.
Yes. PRESSGUARD covers all three. Feedstock, resin system and press type drive the formulation more than the panel type does, so we ask about press configuration and resin before recommending a grade.
Belt spray applies the agent directly to the press surface continuously, which suits continuous presses and gives even coverage at speed. Mat or caul application puts the barrier on the product side and is common on multi-opening presses. Some mills run both, and the chemistry differs between them.
Yes. We scope the trial with your team, set the measures before it starts, which normally means build-up rate, applied rate, panel surface quality and cleaning frequency, and run against your incumbent so you finish with data rather than an impression.
At our plant in Sturgeon County, Alberta, with US production at Kissimmee, Florida. We formulate and manufacture our own chemistry, so adjusting a grade to suit your press and resin system is a formulation change rather than a request to a third-party supplier.
