Back to all services

Sahawatthanakit (1988) supplies the consumables used for aircraft paint and surface-preparation work. We supply and deliver the materials; we do not carry out aircraft painting ourselves, and we do not manufacture the chemicals. Scope covers solvents and thinners that can be quoted against a specification (MIL-T-81772B Type I, AMS3180, TT-I-735A isopropyl alcohol), cleaning solvents and thinners by manufacturer code (C25/90S, C28/15), conversion coating for surface preparation (ALODINE 1200), pre-spray wipe cleaner, 6-inch 45-hole sanding discs across grit stages, tack cloths, wide masking film and masking paper, and 200-litre steel drums for collecting paint waste. The conditions aviation units normally impose are our standard delivery terms: manufacturer or company COC, year of manufacture and remaining shelf life certified at delivery, and new stock only. Priced by line and quantity — send the items you need, with specification or code, pack size and quantity, and we will quote.

Standards & Certifications

Every item is quoted against a specification or a manufacturer code that can be traced, never against marketing copy — solvents and thinners reference MIL-T-81772B Type I, AMS3180 and TT-I-735A (isopropyl alcohol); cleaning solvents and thinners reference the manufacturer codes C25/90S and C28/15; surface preparation references ALODINE 1200 conversion coating by product name. The delivery conditions aviation units impose are our standard: manufacturer or company COC, year of manufacture and remaining shelf life certified at the buyer's receipt, and new stock only. We supply and deliver rather than manufacture, and we do not spray aircraft — mixing, application and safety always follow the manufacturer's current TDS/SDS.

complete, with COC

Why buy paint-shop supplies from us
  • • Thinners and solvents to a quotable spec — MIL-T-81772B · AMS3180 · TT-I-735A, or the maker's own code on your purchase order
  • • Conversion-coating chemicals · 6-inch abrasive discs · tack cloths · masking film and paper · 200-litre steel drums
  • • Kitted by work step — surface prep → conversion coating → masking → spraying → equipment cleaning — on one quotation
  • • Delivered with a certificate of conformance · year of manufacture and remaining shelf life stated at delivery · new stock only · we supply, we do not paint aircraft

Common Questions

Before you send an RFQ

Q1.Does Sahawatthanakit carry out the painting as well?+
No. We supply and deliver the materials for paint and surface-preparation work; we do not spray aircraft and we do not manufacture the chemicals. The application and the quality of the finished surface belong to the maintenance unit or its approved contractor — our job is that the materials they need are to the right specification, fully documented, and there on time.
Q2.What do you need in order to quote accurately?+
Three things: the specification or manufacturer code (MIL-T-81772B Type I, AMS3180, TT-I-735A, or codes such as C25/90S and C28/15); the pack size and unit you want (gallon, pail, roll, sheet); and the quantity with the date you need it. If you already hold an RFQ or a previous purchase order, send it as it is — we will quote against your own line numbers so your purchasing side can check it line for line.
Q3.How are shelf life and certification handled?+
As a standard delivery condition, not an extra: manufacturer or company COC, year of manufacture stated, and remaining shelf life certified at the buyer's receipt, new stock only. Many aviation units set a minimum remaining shelf life. If yours does, tell us at enquiry stage so we select lots against it from the start, rather than discovering it at goods inspection.
Q4.Can we order a single grit of sanding disc?+
Yes, though surface preparation is normally worked as a sequence from coarse to fine rather than one grade. We would rather quote the set that matches the stages you actually run — tell us which grits and how many of each, and we will specify 6-inch 45-hole discs to match the backing pads you already use.
Q5.What are the 200-litre steel drums for?+
Collecting the paint waste produced when equipment is cleaned down and work is made good — waste that has to be segregated and disposed of under the unit's own regulations. Supplying the drums in the same order as the materials keeps the job from stopping while someone finds a container.
Q6.What materials does one aircraft repaint need, in order?+
Generally in the order of the job — (1) surface preparation: cleaning solvent, wipe cleaner and sanding discs from coarse to fine; (2) conversion coating on aluminium before primer; (3) masking: wide film and rolled masking paper to keep paint off what is not being sprayed; (4) spraying, with a tack cloth to lift dust beforehand; (5) clean-down of equipment with specification-grade thinner, and paint waste collected in 200-litre steel drums. We supply the consumables in stages 1–5 and quote them as one set matching the stages your unit actually runs — just tell us which.
Q7.We also need the aircraft primer or topcoat — how do we handle that?+
Aircraft primers and topcoats are normally called up by the unit's own specification or the airframe maker's (for example MIL-PRF-23377 for primer, MIL-PRF-85285 for topcoat). Send the specification number, the manufacturer's code, the colour (an FS or RAL reference if you have one), the pack size and the quantity. We check sourcing against that specification and confirm the delivery conditions — COC, year of manufacture, remaining shelf life — before we quote. We do not guess a product in place of a specification your unit has set.
Q8.What is a conversion coating, and where does it sit in an aircraft repaint?+
It is a metal-surface treatment, mainly for aluminium, that forms a thin layer on the bare metal after surface preparation to help resist corrosion and to give the primer something to hold on to. It is usually specified under standards such as MIL-DTL-5541 and applied before primer. We can quote this group of products (ALODINE 1200); the method, concentration and contact time are always those of the manufacturer's datasheet and your maintenance unit's own procedure.

Ordering Aircraft Paint Materials That Pass Goods Inspection — Specification, Grade, and Shelf Life at Receipt

A procurement guide to aircraft paint and surface-preparation materials: why writing MIL-T-81772B alone is not a specification (it covers three types, of which Type I is the polyurethane thinner), why remaining shelf life has to be set at the buyer's receipt when MIL-T-81772B Type I carries only one year from date of manufacture, the grades of TT-I-735, what it means that AMS3180 was stabilized in 2015, and how abrasives should be ordered as a sequence rather than a single grit.
