Leather wax emulsions are aqueous dispersions of synthetic or natural waxes used in finish to give slip, fill, plate and emboss behaviour, and a silky or waxy handle. They are not the main film-former; they modify acrylic and PU seasons in base coat, ground and aqueous sealers.
What leather wax emulsion are
Leather wax emulsions are aqueous dispersions of synthetic or natural waxes used in finish to give slip, fill, plate and emboss behaviour, and a silky or waxy handle. They are not the main film-former; they modify acrylic and PU seasons in base coat, ground and aqueous sealers. Dyna Glycols offers VENWAX S, a soft synthetic-wax emulsion for upholstery and garment grounds and for base coats that must plate and emboss cleanly.
Wax in finish reduces tack of soft acrylics, improves plate release, fills minor grain defects and changes the light scatter of the surface. Too much wax can hurt rub fastness and adhesion of later coats. The catalogue grade is therefore specified by solids, pH and recommended parts in a season next to pigment and binder, not as a standalone top.
How Dyna Glycols manufactures leather wax emulsion
VENWAX S is produced as a white to cream pourable liquid at about 13% solids, pH about 8.5, freely soluble in water. The wax is synthetic. Batches are released against appearance, solids and pH.
Emulsions must be protected from frost and from contamination with solvents or strong electrolytes that can break the dispersion. Stir before taking from the drum.
Typical grades in this range
VENWAX S is the standard soft wax emulsion. Custom wax hardness or solids can be discussed for special plate or pull-up effects.
- VENWAX S — soft synthetic wax emulsion; silky handle, fill, plating and embossing
- Use in base coat and aqueous sealing coats; upholstery and garment grounds
Where leather wax emulsion are used
Upholstery base-coat example from the product page: 100 parts pigment, 30 parts VENWAX S, 200–300 parts water, 100 parts acrylic binder, 150 parts PU binder, 50 parts protein binder; apply two to three coats. That recipe is a starting season, not a universal formula.
Garment grounds use wax emulsion for a filled, sewable surface before colour. Shoe upper may use a smaller wax fraction when plate and mill are required without a greasy top.
Aqueous sealing coats before lacquer can include VENWAX S to reduce tack into the iron. Always check wet rub after wax is added; compensate with binder or a stronger NC/PU top if rub falls.
How to specify leather wax emulsion
State article, whether the wax is for base, ground or sealer, required plate/emboss temperature, and the acrylic/PU ratio already in use. Share solids of the current wax if matching.
If a harder, more carnauba-like slip or a pull-up oil-wax is required, say so; VENWAX S is a soft synthetic emulsion, not a pull-up oil.
Quality, documents and supply
Lots are released against appearance, solids and pH. SDS and COA follow verification. Plate, feel and rub should be tested on the customer season after the intended ironing.
Store frost-free; typical shelf life six months. If the emulsion separates slightly, stir; if it has broken into curds after frost, do not use it in a critical finish.
Practical notes on leather wax emulsion
Wax is a modifier. Changing VENWAX S parts by ten in a season will change tack and gloss more than changing binder by the same amount. Keep a written season card.
Protein binder in the example season adds another handle. If the tannery is protein-free, omit that line and rebalance acrylic/PU rather than overdosing wax.
Compatibility: add wax to the water/binder mix with stirring. Dumping wax into a strongly solvent top is not the use; WS lacquer is a different phase.
Embossing: wax helps the plate release and can hide minor defects. It will not hide a loose empty belly; that is a retan/fatliquor problem (see VENTAN fillers).
Silky handle from VENWAX S is a finish effect. If the crust is already harsh, fix fatliquor (VENSOFT SFC/CWS) first, then use less wax in finish.
Dyna Glycols samples VENWAX S with VENRES 10/20/76 and VENOLAC LMF so plating, gloss and rub can be judged together.
Ordering and evaluating leather wax emulsion
Send the application, the analytical window and the pack size when you request a laboratory sample of leather wax emulsion. SDS, TDS and COA follow a short company check. Handle and store the grade as the SDS describes.
