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.

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.

An Invoice of 107,000 Baht Pays 104,000 Into the Bank — Thai Withholding Tax Is Computed on the Pre-VAT Base

Thai withholding tax is always computed on the amount before VAT. A service invoice of 100,000 baht plus 7% VAT totals 107,000, but the 3% withholding applies to the 100,000 base — 3,000 baht — so 104,000 is what actually arrives. Why computing it on the gross total skews every invoice in the same direction, why services are withheld on but pure goods sales generally are not, and why the withheld money is not lost, only slow.

The price-validity line is not a ritual at the bottom of a quotation — it is the ceiling on the cost and currency risk you carry on the customer's behalf, and the most legitimate reason to make a closing call. How to set the validity period to match the product, how to use the near-expiry window as the golden moment, and how to handle an already-expired quote without damaging the relationship.

Following Up on a Quote in Thailand Without Being Rude — Face-Saving Scripts and the Cadence That Works

Many Thai customers reject a price by going silent, because saying "too expensive" out loud feels like making the seller lose face — how to follow up in a way that opens the door to negotiation instead of forcing a yes/no, with a three-beat script: the first follow-up, the pre-expiry call, and the graceful close after a long silence — and why the cadence must be counted in working days, never on holidays.
