Release Coating Systems and Agents
Releasing the potential of silicone performance
Silicone release coatings are applied at low weights onto a wide range of substrates using many different techniques. The silicone release coatings form a crosslinked non-stick surface useful in protecting pressure-sensitive adhesives until the moment of use, as well as many other sticky materials such as bituminous compounds, composite prepregs, and food. They are available in a variety of delivery systems (e.g., solvent-based, solventless or emulsion) utilizing a range of cure chemistries, such as platinum- or rhodium-catalyzed addition curing or tin-catalyzed condensation curing.
From food and healthcare to graphic arts and labels, silicone release coatings from Dow provide a range of benefits to deliver the right solution for any application. Competitively priced and reliably supplied, they offer:
- Reliability – robust curing below 35 ppm platinum
- Increased flexibility – in controlling release, cure and coat
- Faster line speeds – breaking records without misting
- Good coverage – bath life, anchorage and release ability
- Improved conversion speeds and ease of dispersal
Silicone release agents are used as additives in mold release applications where they enable quicker release of products made in molds, such as tires or food containers. They also provide lubricity and slipperiness in applications such as newspaper presses and conveyor belts that use rollers.
Silicone release agents from Dow offer many benefits in industrial, food-contact manufacturing and film and paper coating applications. Their nonstick properties can help enable:
- Faster throughput
- Cleaner finished products
- Less material waste
- Longer life of molds and machinery
