KSL staubtechnik

What KSL staubtechnik does

KSL staubtechnik gmbh is a privately held German specialty manufacturer founded in 1949 in Lauingen an der Donau, producing three families of industrial powders: anti-set-off powders for sheet-fed offset printing (K4/K4 plus, S5/S5 WL, L3 — including the world's first anti-set-off powder K4/15 developed with Fogra in 1951), separating and interleaving powders for the glass (eskal, eseco, esplas) and plastic-film (esstar) industries, and standardized/custom test dusts (Arizona ISO 12103-1, KSL-series, MIL-STD, ECE, DIN, EN, IEC variants) used in product qualification, environmental simulation, filter and IP-code testing, and increasingly in PV and ADAS sensor validation. The company's underlying technology is centered on narrow particle-size distribution classification, laser-diffraction analysis certified to ISO 13320:2009, and multi-stage quality control; it holds ISO 9001 (since 1998), ISEGA food-contact, Kosher/Pessach, BG ETEM 'low emission product' (22 certified powders), and ISO Class 8 clean-room certifications, all manufactured exclusively in Germany.

The business model is B2B sales-led, with a direct field-sales force and application-engineering specialists providing technical consultation, complemented by international distribution partners for global delivery from Germany. Revenue is generated almost entirely through hardware sales of branded powder SKUs in 1kg/3kg/25kg pack sizes, with ancillary contract filling under ISO 8 clean-room conditions as a service line; pricing is not publicly disclosed. Customer segments are organized vertically across printing, glass, film, and testing/quality assurance — each with its own technical requirements (food-contact, kosher, low fine-dust, narrow PSD) — and the company markets through LinkedIn, YouTube, a content-rich website, and participation in drupa, glasstec, and POWTECH trade shows.

KSL's strategic positioning is that of a quality and certification leader in a niche too small for diversified chemical majors to serve efficiently; the 75-year track record, Fraunhofer research partnerships, and continuous certification cadence reinforce defensibility. The principal growth vectors are ESG-driven microplastic-free glass powders (eseco, 2024), high-growth electronics and mobility test applications (PV soiling, ADAS sensor dust), and clean-room toll-filling services — each incremental rather than transformational, consistent with a stable, founder-family-style industrial GmbH.

Core offering

KSL staubtechnik manufactures and sells sustainable industrial powders and dusts from its Lauingen, Germany facility, organized in three lines: anti-set-off spray powders for sheet-fed offset printing (K4/K4 plus, S5/S5 WL, L3 series), separating/interleaving powders for glass and plastic film applications (eskal, esstar, eseco, esplas), and standardized plus custom test dusts for quality assurance and environmental simulation (Arizona dust and KSL series per ISO, DIN, MIL-STD, ECE, JIS, SAE standards). The company also offers contract filling in clean room ISO 8 conditions, application consulting, and custom product development.

Product overview

KSL staubtechnik is a quality manufacturer of industrial powders and dusts with three core product lines: (1) Anti-set-off powders (Druckbestäubungspuder) including K4/K4 plus (calcium carbonate-based, world's first developed in 1951), S5/S5 WL (starch-based, including water-repellent variant), and L3 (water-soluble sugar derivative); (2) Separating/interleaving powders for film and glass including eskal (calcium carbonate for glass, launched 1998), esstar (starch-based for plastic film, launched 1999), esplas H60/H130 (glass applications), and eseco (microplastic-free for glass, launched 2024); and (3) Test/standard dusts including Arizona dust (ISO 12103-1), custom KSL test dusts (KSL 11046, 11047, 12050, 14017, 14019, 14027, 15088, spheres), and dusts per international standards (DIN, EN, ISO, IEC, MIL-STD, ECE, JIS, SAE). All products are manufactured in Germany with multi-stage quality assurance.

Products and services

• K4 & K4 plus Anti-Set-Off Powders Anti-set-off spray powders based on natural mineral calcium carbonate (CaCO3), available in regular and coated (K4 plus) variants. K4 series provides narrow particle size distribution, minimal dust, no static charge, temperature stability, non-flammability, and ISEGA food-safe certification. Intended for sheet-fed offset printing operations to prevent ink set-off, blocking, and glass plate effect.
• S5 & S5 WL Anti-Set-Off Powders Starch-based anti-set-off spray powders for sheet-fed offset printing. The S5 WL series features hydrophobic, water-repellent properties for use with water-based varnishes. Both S5/S5 WL lines are ISEGA-certified for food contact and Kosher-certified. Targets commercial and packaging printers requiring starch-based alternatives to mineral CaCO3 powders.
• L3 Water-Soluble Anti-Set-Off Powder Water-soluble anti-set-off spray powder based on a natural sugar derivative, developed in 1982. Suitable for offset printing operations requiring water-soluble formulation behavior and clean removal during downstream processing.
• eskal (plus) Glass Separating Powder Mineral separating powder based on naturally pure calcium carbonate (CaCO3), originally developed for the automotive glass industry. Available in narrowly classified fractions from approximately 3 µm to 150 µm median particle size, plus coarse granules up to 4 mm. ISEGA and Kosher certified for food packaging applications. Used for glass sheet interleaving to prevent adhesion and surface damage.
• esstar (plus) Film Separating Powder Separating powder for plastic film production and processing based on native starch with soft, roundish particles and smooth surfaces. Available in 6 types from approximately 15 µm to 60 µm median particle size, including a hydrophobic variant. Targets blown film extrusion, flat film production, and sausage casing manufacturing applications requiring food-compliant separating agents.
• eseco Microplastic-Free Glass Interleaving Powder Microplastic-free and biodegradable glass interleaving powder developed in 2024. Environmentally sustainable alternative for float glass separating applications, addressing regulatory and sustainability pressures to replace conventional polymer-containing interleaving powders with biodegradable equivalents.
