SDI offer a range of polymer formulations to balance the best cleaning performance against the ease of processing a particular substrate.
Dark Blue (High Tack) – silicone-based polymer suitable for rigid substrates and high levels of contamination, cleaning particles down to1μ in size.
Red (Medium Tack) – silicone-based polymer suitable for semi-rigid substrates, cleaning particles down to 1μ in size.
Black (Low Tack) – silicone-based polymer suitable for flexible substrate, cleaning particles down to 1μ in size.
Light Blue (Thin Film) – silicone-based polymer suitable for the most delicate substrates, cleaning particles down to 1μ in size.
Yellow – silicone-free polymer suitable for most substrates, cleaning particles smaller than 1μ in size. Uses DRS1-PLAS Adhesive Pads.
IMPORTANT!
Material thickness is only a guide to how well a substrate can be processed. It is rigidity rather than thickness that determines a substrate’s ability to be cleaned by our systems. If in doubt, samples will be sent to the SDI laboratory for testing at the SDI AMERICAS.

Widest variety of polymer types to ensure the correct formulation for every task.
Selection of widths and handles to give total flexibility for customers’ dust-related issues.
Quality bearings used to ensure no plastic-on-plastic abrasion and dust creation.
High coat weight adhesive pad ensures maximum retention of removed particles.
Silicone-based and silicone-free versions.
Rollers are replaceable.
THE SDI PRINCIPLE
The SDI cleaning principle consists of two linked processes.
Specially formulated polymer rollers gently lift loose, dry contamination away from any flat surface.
Specially formulated polymer rollers gently lift loose, dry contamination away from any flat surface.
HOW DOES IT WORK?
The Dust Removal System is the ultimate tool for cleaning particulate contaminants from flat surfaces. Unwanted particles as small as one micron are readily removed from the substrate.
Gently pass the DRS hand roller over the flat surface to be cleaned. The roller’s polymer surface lifts particulate matter from the substrate. No pressure is required.
Now, pass the DRS hand roller over the DRS1 adhesive pad. The pad’s surface energy is higher than the roller’s, so the particulate is transferred, leaving the roller clean, and ensuring no cross- contamination.
Each sheet of the pad can absorb many passes of the hand roller before it is discarded.

DRS PRODUCTS
DRS1 Adhesive Pads (silicone-lined) The hand roller is only part of the process in cleaning the substrate of unwanted particulate. The DRS1 Adhesive Pads trap and store the collected contamination, ensuring no re-transfer back to the DRS roller and on to the substrates. The extremely high coat-weight of adhesive ensures that the maximum amount of contamination is stored before the top sheet of the pad is full. DRS1 Adhesive Pads are slightly larger than the 305mm width of the DRS12, and are thus suitable for both DRS6 and DRS12. Use two pads side-by-side with the DRS18. DRS1 Adhesive Pads are sold in packs of 5 pads.
DRS1-PLAS Adhesive Pads (silicone-free) These special Adhesive Pads are used with the “Y”- type polymer formulation of hand roller, ensuring that the complete system is silicone-free
DRS4 Pad Holder The strong pad holder provides a workstation for the DRS6 or DRS12 roller (with 30°grip angle) and DRS1 Adhesive Pads
Replacement roller cartridges and handles Can be ordered from your nearest SDI office or distribution partner
