Product Overview
VM&P Naphtha (Varnish Maker's & Painter's Naphtha), Technical Grade, CAS 64742-89-8, is a petroleum-derived aliphatic solvent known for its fast evaporation. Coatings shops reach for it to thin oil-based paint without dragging out dry times. Maintenance crews use it for degreasing and tool cleanup. Formulators use it as a carrier in adhesives. It is a working solvent, not a specialty reagent — and that is exactly why it earns a place on the shop floor.
We offer it in sizes from 1 quart bench containers up to 275 and 330 gallon totes, packed and shipped as fully regulated Class 3 flammable liquid from our Taylor, Texas warehouse.
Why This Concentration
Technical grade is the workhorse designation for this solvent. Buyers thinning paint, flushing spray equipment, or cutting adhesive formulations typically specify technical grade because the job depends on solvency and evaporation behavior, not on a tight analytical specification. If your process documentation calls for a specific distillation range or assay, review the technical data sheet for this product before ordering — we supply a TDS so you can match the material to your spec rather than guessing.
The trade-off to plan around is not purity — it is volatility. A fast-evaporating solvent means shorter flash-off between coats and quicker tool turnaround, but it also means vapor builds quickly in enclosed spaces. Ventilation and ignition control, covered below, are part of choosing this product.
Chemical Profile
VM&P Naphtha carries CAS number 64742-89-8 in our published product data. It is a petroleum distillate with a predominantly aliphatic hydrocarbon character, which is what gives it its balance of solvency for oils, greases, and alkyd resins with an evaporation rate faster than mineral spirits — the practical reason painters and varnish makers adopted it in the first place. For lot-specific analytical values, request the certificate of analysis and technical data sheet, both of which we provide for this product.
Industrial Applications
-
Paint thinning: Cuts oil-based paints, varnishes, and enamels to improve flow and application, then evaporates fast enough to keep recoat windows short. This is the use the name comes from.
-
Degreasing and equipment cleanup: Dissolves oils and greases from tools, spray guns, and parts in manufacturing and maintenance work, then flashes off rather than leaving a slow-drying residue.
-
Extraction solvent: Used in industrial and research settings to extract organic compounds from mixtures where an aliphatic, volatile solvent is required.
-
Adhesive formulations: Serves as a carrier solvent in solvent-borne adhesives, controlling viscosity during application and leaving the bond line as it evaporates.
-
Fuel blending: Blended into fuel formulations as a light petroleum distillate component.
Handling & Storage
The signal word is Danger (per the product's GHS classification). This material is classified H225 Highly flammable liquid and vapour, H304 May be fatal if swallowed and enters airways, H315 Causes skin irritation, H336 May cause drowsiness or dizziness, H340 May cause genetic defects, H350 May cause cancer, H361, and H373 May cause damage to organs through prolonged or repeated exposure (per the product's GHS classification). Treat those statements as the operating brief, not fine print.
In practice: ground and bond containers during transfer, eliminate ignition sources, and work with ventilation sized for a fast-evaporating solvent — vapor concentration climbs quickly in still air. Wear solvent-resistant gloves and eye protection; do not rely on bare-hand tolerance. Never siphon by mouth; the H304 aspiration hazard is why. Store closed containers in a cool, well-ventilated area away from heat, sparks, open flame, and strong oxidizers. Keep quantities at the point of use small and return stock to flammable-liquid storage.
Hazmat & Shipping
This product ships as UN1268 (per 49 CFR 172.101), hazard class 3 flammable liquid (per 49 CFR 172.101), packing group II (per 49 CFR 172.101), under the proper shipping name Petroleum distillates, n.o.s. (VM&P naphtha) (per 49 CFR 172.101). Every order leaves our dock in UN-specification packaging with hazmat labeling and shipping papers prepared to that classification. If your receiving dock logs hazmat inbound, those are the four data points your team will need.
Documentation
A Safety Data Sheet ships with every order and is available in English, Spanish, French, and Japanese. A lot-specific Certificate of Analysis is available for this product, along with a Technical Data Sheet covering product specifications. If your EHS or quality team needs documents before purchase for approval workflows, request them with your quote.
Why Buy from Alliance Chemical
We package this solvent across the full range a buyer actually needs — 1 quart and 1 gallon cans for bench and touch-up work, 5 and 15 gallon containers for shop use, and 55 gallon drums through 275 and 330 gallon totes for production — every size prepared and documented as UN1268 Class 3 hazmat by a team that does this daily. Alliance Chemical has operated since 1998 and has served more than 50,000 customers with industrial chemicals shipped from Taylor, Texas.
