3M 21825 is an industrial polyethylene temporary surface protection tape designed to protect semi-gloss, high gloss, and polished surfaces. 


This material has a medium tack adhesive system designed to stick to painted surfaces, aluminum, stainless steel and plastic. The acrylic adhesive removes cleanly from surfaces without leaving behind any residue.

3M 21825 protective film protects surfaces from UV exposure and weather conditions for up to 3 days. This clear colored surface protection tape is used in many industries including automotive, aerospace, appliance, military, electronics, specialty vehicle, and general industrial.

3M protective film provides protection against dust, dirt, scratches, abrasions and UV exposure. All of which are elements that products are exposed to during processing, handling, shipping, and storage. 3M 21825 provides good conformability for both hand and machine (automation) applied applications. By protecting these surfaces you can ensure your customers receive products that are in prime condition. This can save you time and money on returns and repairs.

Converting 3M 21825

3M 21825 can be easily die cut and converted into custom formats depending on your needs.

SlittingStrouse can slit rolls of protective film to custom widths. This provides you tape in the exact width you need for your task at hand. No excess or waste and no more using rolls that are too large and bulky or too small to get the job done. 

Die Cutting: This is the process of cutting a wide roll of surface protective film into a custom shape or usable part for your process. Parts can be cut into different formats to fit seamlessly into your assembly.

Individual piecesProtective films can be laminated with liner on the adhesive leaving no exposed adhesive. This means that when parts are die cut they are provided as individual pieces that can be placed inside a bag.  

Sheeted Parts – Some assembly processes require multiple shapes or parts of the same material. This is where sheeted parts come in handy. Multiple parts can be cut onto a single sheet ensuring that your employees will use all of the required parts during assembly. This reduces error in your process as well as the potential for product failure.

Die Cut Parts on a Roll – This is our most popular format for providing die cuts. Custom cut parts can be provided on a liner in the form of a rolled good. This allows for hundreds or thousands of parts to fit on a single roll. This makes application of die cut parts easy and efficient as parts can be removed from the roll and the next part is ready to be peeled and placed.

Tabs or Extended LinersDie cut solutions are great for hand assembly or automated processes but sometimes removing the backing from an adhesive die cut can be difficult. Strouse simplifies this process by adding a tab to the part or extended liners that make it easy to remove the liner and place the adhesive. Liners can also be split backed saving your assembly team the frustration of removing thin liners while saving you time and money in the process.
