Palm coating is the detail that decides whether a work glove grips a wet pipe, survives an oily shop floor, or feels good handling small parts - and the coating vocabulary (foam nitrile, sandy nitrile, micro-foam, PU, latex crinkle) is exactly the part buyers nod along to without really knowing. Here is a working guide to glove coatings, written so you can spec the right grip for the job.
Why Coating Is a Real Engineering Choice
On a coated work glove, the liner provides the fit and the coating provides the grip, the durability, and the protection - and matching the coating to the working environment is the difference between a glove workers love and one they cut the fingertips off. The wrong coating slips on oil, wears through in a week, or feels so stiff that workers remove it for fine tasks. Coating is also a significant cost driver and an MOQ factor. So it deserves the same deliberate choice as the liner material - yet most buyers leave it to the factory and accept whatever is cheapest to run, which is rarely what the job needs.
Nitrile Coatings: Flat, Foam, Sandy and Micro-Foam
Nitrile is the most versatile and popular coating, and it comes in distinct finishes that behave very differently. Flat/smooth nitrile is durable and oil-resistant but slippery when wet - good for dry, abrasive handling. Foam nitrile is the all-rounder: tiny air pockets channel away light oil and give a good dry-and-light-wet grip, dominating general light-industrial PPE. Sandy (or gritty) nitrile adds a rough texture for aggressive grip in oily and wet conditions - the choice for oil-and-gas and heavy automotive. Micro-foam is a finer foam for a softer feel with good grip. Naming the exact nitrile finish, not just nitrile, is what gets you the right glove.
PU (Polyurethane) Coatings for Precision Work
Polyurethane coating is thin, flexible, and breathable, giving excellent tactile sensitivity and dexterity - it is the standard for precision work: electronics assembly, small-parts handling, inspection, and light assembly. PU grips well in dry conditions and feels almost like a second skin, but it is less abrasion- and oil-resistant than nitrile and not for wet or heavy work. PU-coated gloves are usually thin 13- or 15-gauge nylon liners, prized where feel matters more than ruggedness. If your end use involves handling small components or anything requiring finger sensitivity, PU is usually the answer over a thicker nitrile.
Latex and PVC Coatings
Latex (crinkle) coating offers superb grip, especially in wet conditions, and excellent abrasion resistance at low cost - the classic crinkle-latex builder's glove. Its drawbacks are poor oil resistance and the latex-allergy issue, which rules it out for some buyers. PVC coatings - including the familiar PVC dots on the palm of a cotton glove, and full PVC dip - are cheap, waterproof, and good for general handling and chemical splash, though stiffer and less breathable. PVC dotted gloves are a high-volume, low-cost grip-enhancement for general-purpose cotton gloves. Each has a clear price-and-performance niche; none is a do-everything coating.
Coating Coverage: Palm, 3/4, or Full Dip
How much of the glove is coated is a separate decision from the coating type. Palm-coated (palm and fingers only) is the most common - grip where you need it, breathability on the back. 3/4-dipped extends coating up the sides and knuckles for more protection and splash resistance. Fully-dipped coats the entire glove for liquid and chemical protection at the cost of breathability. Match coverage to the hazard: palm coat for dry handling and breathability, 3/4 for more splash exposure, full dip for liquids and chemicals. Coverage affects cost and comfort, so specify it rather than defaulting to palm coat for everything.
Gauge, Liner and How Coating Interacts
Coating does not exist in isolation - it sits on a knitted liner whose gauge (7/10/13/15) sets the base thickness and dexterity. A thin 15-gauge nylon liner with PU gives a precision glove; a 13-gauge HPPE liner with sandy nitrile gives a cut-resistant oil-grip glove; a 10-gauge poly-cotton with foam nitrile gives a rugged general glove. The liner and coating are a matched pair, and a good spec names both. Cut resistance, if needed, comes from the liner (HPPE, glass, steel blends), and the coating adds grip on top - see our cut-resistant standards and materials guide for the liner side.
How to Spec and Vet Coating Quality
Beyond naming the coating, quality varies within each type, and the failure mode is the coating cracking, peeling, or delaminating from the liner. In a sample, flex the coated area hard and check the coating does not crack; check the coating is evenly applied with no thin spots, especially at fingertips; and confirm adhesion to the liner. In bulk, coating defects (cracking, thin spots, peeling) should be on your inspection defect list. Ask the supplier about coating thickness and the dipping process. A factory that runs its own coating line and can discuss finish and coverage fluently is a real coated-glove maker; one that is vague is buying in coated blanks. The inspection guide covers building coating defects into AQL.
Our Honest Position on Coatings
We run our own coating lines and treat coating as the engineering choice it is - we will ask about your working environment (dry, oily, wet, fine-handling) and recommend the specific finish (foam, sandy, micro-foam nitrile, PU, latex crinkle, PVC) and coverage (palm, 3/4, full) that fits, rather than defaulting to the cheapest run. We match the coating to the liner and gauge as a pair, and we put coating adhesion and coverage on the inspection list because cracking and peeling are the classic coated-glove failures. Tell us the job and we will spec the grip; tell us only coated work gloves and you will get our default, which may not be your job's answer.
