SQ-SE 349L – High-Gloss Dimethicone Emulsion for Car Care, Leather & Furniture

A car that turns heads in the parking lot, a leather sofa that still feels brand new, a table that stays dust-free — these small wins are what make customers repurchase. Behind all three sits the same quiet workhorse: a well-made dimethicone emulsion.

Shine That Streaks, or Shine That Lasts

Car care, leather and furniture brands share one recurring headache: products that promise shine but deliver streaks, oily residue, dust attraction or yellowing. Solvent-based dressings bring odor and VOC concerns, while poorly made emulsions separate on the shelf or fail on water repellency.

High Solids, Real Economy

SQ-SE 349L is a dimethicone emulsion stabilized with nonionic emulsifiers, with an impressive 58.0–62.0% solids content. This high active level gives formulations real economy: dilute as needed and still enjoy strong, consistent performance across automotive detailing, leather care, textile finishing and household cleaning. One drum serves many product lines, simplifying inventory and unit cost.

Automotive Silicone Dressing with a Professional Finish

On car paint, trim and tires, SQ-SE 349L forms a smooth film with excellent gloss and pronounced water repellency — the beading effect that signals professional-grade protection. As an automotive silicone dressing, it leaves a deep, even shine with no greasy buildup, and its good wetting and slip effect makes application effortless, whether wiped on or sprayed. Detailing studios and consumer brands alike get showroom results that survive the next wash.

Leather & Furniture: Conditioned, Not Yellowed 

For leather, the emulsion conditions and lubricates, restoring suppleness and a natural sheen while remaining soft to the touch — and, crucially, without yellowing, the silent killer of light-colored leather goods. Furniture manufacturers and care brands can count on the same anti-dust, gloss-enhancing performance on wooden and synthetic surfaces, keeping showrooms and homes cleaner for longer. Textile finishing also benefits from a soft, non-yellowing lubricated hand-feel.

Compatible, Dilutable, Production-Ready 

Formulators will appreciate its good compatibility with other ingredients. SQ-SE 349L can be used directly or diluted, mixes to uniformity with simple stirring, and suits lotion, spray, mousse, roll-on and cushion formats. After dilution it should be used promptly, keeping production planning simple and waste low. 

Reference Formulation: Silicone Dressing Spray

A typical starting point: one formulation that works on dashboards, tires, trim and leather seats. SQ-SE 349L supplies the gloss and water-repellent film, while a light nonionic system keeps the spray stable and streak-free.

One Silicone Emulsion for the Whole Care Spectrum

From a showroom-fresh car finish to supple leather seats and dust-free furniture, SQ-SE 349L is the silicone emulsion that covers the full care spectrum. it is the practical choice for brands that need gloss, protection and versatility in a single raw material.
