Factory guide to sourcing gloves for SLA and DLP resin printing, including nitrile, chemical gauntlets, cut liners, IPA wash stations, EN ISO 374 checks, MOQ, AQL, lead time and export packing realities.
Start With the Wet Resin Task, Not the Printer Brand
For SLA, DLP and LCD resin printing, glove selection should start with the liquid and the work step, not the printer name. Pouring UV photopolymer from a 1 kg bottle, wiping a vat film, lifting a basket from 95 percent IPA, scraping a build plate, clipping 2 mm support points and packing a cured model are different exposures. One glove SKU rarely covers all of them well. The main wet hazard is uncured acrylate or methacrylate resin on the palm and fingers, often followed by isopropyl alcohol in a 10 to 18 litre wash tub. Thin disposable nitrile can be useful for short splash contact, but a 0.08 mm glove and a 0.45 mm flock-lined nitrile gauntlet should not be treated as the same product. Thickness, cuff length, grip texture and change frequency matter. Most resin SDS documents ask for chemical-resistant gloves, commonly nitrile, neoprene or butyl rubber. That is a starting point, not proof of compatibility. For EU PPE discussions, EN ISO 374-1 covers chemical risks and EN ISO 374-5 covers microorganisms where claimed. Resin printing is normally a chemical-splash problem, not a biohazard problem. If the same operator uses metal scrapers or flush cutters after washing, EN 388 mechanical protection also enters the specification.
What GloveMark Can and Cannot Make
GloveMark is a Yiwu work-glove factory. Our in-house production covers knitted liners, dipped palm coatings, sewn textile gloves, leather work gloves, logo application and export packing. Common knit gauges are 10 gauge, 13 gauge, 15 gauge and 18 gauge. Liner options include polyester, nylon, HPPE blends and glass-fibre or steel-fibre reinforced cut yarns where the task needs cut resistance. Coatings include PU, nitrile foam, sandy nitrile, smooth nitrile and latex for general work gloves. We do not make thin disposable examination nitrile gloves on our own lines. Those products are made on ceramic hand-former dipping lines with leaching, chlorination or polymer coating, online pinhole checks and high-volume box packing. If a buyer needs ASTM D6319 disposable nitrile exam gloves, we can only handle that through a qualified partner route, and it must be quoted separately from our in-house knitted and dipped gloves. What we can make directly for resin rooms includes 13 gauge or 15 gauge cut-resistant liners with nitrile palm coating for cured-part trimming, 15 gauge nylon PU inspection gloves for clean model handling, and reusable coated work gloves for packing, jig handling and machine maintenance. For full chemical gauntlets used in wet resin or IPA immersion, we must confirm whether the glove is from our own range or from a specialist chemical-glove partner with the correct EN ISO 374 or ASTM F739 documentation.
Build a Three-SKU Resin Glove Range
A practical 3D printing resin gloves programme usually needs three SKUs. The first is a disposable nitrile glove for short wet contact, often 4 to 8 mil in trade language, powder-free, changed after contamination and not reused after swelling or tearing. The second is a longer reusable chemical glove, usually 300 to 330 mm long and about 0.38 to 0.55 mm wall thickness, for vat draining, wash baskets, spill wiping and handling IPA-soaked parts. The third is a cut or abrasion glove for dry finishing after the part is cured and washed. For cured-part finishing, we normally sample a 13 gauge HPPE blend or HPPE-glass liner with nitrile foam or sandy nitrile palm. EN 388:2016+A1:2018 is the relevant mechanical standard, especially the ISO 13997 cut letter from A to F. Many resin workshops do not need level F. A target such as 4X42B or 4X43C can be more realistic when operators need fingertip feel for small parts, miniatures or dental models. Over-specifying cut level can make the glove stiff and increase non-use. For wet chemical work, EN ISO 374 permeation data is more important than EN 388. Ask for the tested chemicals, breakthrough level and test method, not only the beaker pictogram. IPA resistance does not automatically prove resistance to a proprietary resin blend containing acrylates, methacrylates, photoinitiators, pigments and fillers. No factory should honestly promise universal resin resistance from a catalogue page without reviewing the SDS or testing against the buyer’s actual liquid.
Put These Details in the RFQ
A useful RFQ should name the resin chemistry where known, the wash solvent, contact time and station layout. A workable example is: UV acrylate photopolymer, 95 percent IPA, splash contact under 10 minutes, no full immersion except basket lifting, support removal after post-cure, sizes S to XL, 12 pairs per polybag, 120 pairs per export carton. That allows us to quote a 15 gauge nylon PU glove separately from a 13 gauge HPPE nitrile cut glove and a 330 mm chemical gauntlet. For knitted coated gloves, specify gauge, yarn, coating, cuff and target standard. A cured-part trimming glove could be 13 gauge HPPE blend, sandy nitrile palm, knit wrist, dark grey liner, black coating, EN 388 target 4X42B. For clean cured model handling, a 15 gauge nylon liner with white PU palm gives better dexterity but has an open knit back, so it is not a liquid barrier. For wet resin, do not specify an open-back work glove as the primary PPE. Decoration has limits in resin rooms. We can apply woven cuff labels, heat-transfer size marks, printed polybags, carton marks, EAN or UPC barcodes and private-label header cards. We avoid heavy logo printing on the working palm because IPA and sticky resin can attack ink and reduce grip. For mixed-size labs, colour-coded cuffs by size are more useful than a large brand logo, especially when operators change gloves several times per shift.
Testing, Samples and Proof
For EU buyers, request PPE files under Regulation EU 2016/425 and the actual standards claimed, usually EN ISO 21420 for general glove requirements, EN 388 for mechanical risks and EN ISO 374-1 for chemical protection. EN ISO 374-5 should only appear when a microorganism claim is being made. For US buyers, ASTM F739 is relevant for chemical permeation testing. ASTM D6319 applies to nitrile examination gloves, not to a knitted HPPE nitrile-coated cut glove. For our in-house samples, we can check dimensions, coating coverage, cuff stretch, pair weight, colour, packing method and carton marking. A normal 13 gauge coated glove sample takes about 7 to 12 days after yarn, coating colour and size range are confirmed. If the liner needs a special HPPE blend, glass-fibre cut yarn or Pantone-dyed yarn, allow closer to 2 to 3 weeks. Third-party lab testing by SGS, Intertek, SATRA or another recognised lab adds cost and time, and the report only covers the exact construction tested. AQL should be written into the purchase order before production. For work gloves, buyers commonly use AQL 2.5 for major defects and AQL 4.0 for minor defects. Inspection points include missed coating, coating lumps, exposed fingertips, broken elastic, wrong-size pairing, oil marks, open seams on sewn gloves, incorrect barcode labels and carton count errors. Chemical permeation cannot be checked by a final visual inspection table. It needs controlled material sourcing and valid test data.
MOQ, Lead Time and Export Packing
For in-house knitted and dipped resin-workshop gloves, a realistic OEM MOQ is usually 1,200 to 3,000 pairs per style and colour. MOQ moves up when the yarn is special, the coating colour is custom, or the packaging needs printed polybags, header cards or retail cartons. A first production run normally needs 4 to 6 weeks after approved sample, deposit and packaging artwork. Third-party chemical or mechanical testing is outside that timeline unless agreed before sampling. Price depends on fibre, gauge, coating and packing. A 15 gauge nylon PU inspection glove sits in a different price band from a 13 gauge HPPE sandy nitrile cut glove, and both are different from a certified 330 mm chemical gauntlet. We can quote FOB Ningbo or FOB Shanghai with carton dimensions, gross weight and pair price. DDP to an Amazon, 3PL or distributor warehouse must add freight, duty, customs entry, destination handling and any carton relabelling. Gloves are bulky enough that carton cube affects the landed cost. A common packing format for coated work gloves is 12 pairs per inner polybag and 120 pairs per export carton. A carton around 50 x 28 x 32 cm is typical for many coated gloves, but final cube changes with cuff style, coating thickness and size mix. For resin PPE kits containing disposable nitrile boxes, chemical gauntlets and cut gloves, treat the job as kitting with a packing BOM, barcode rules, master carton layout and carton drop-test requirement. It is not the same as shipping one bulk work-glove SKU.
