Techspray 2812-100-69-C 100% MEK Aviation Clean & Prep Wipes, 100/Canister
Techspray 2812-100-69-C 100% MEK Aviation Clean & Prep Wipes, 6 in x 9 in, 100 Wipes/Canister
Techspray 2812-100-69-C Clean & Prep Wipes are pre-saturated with 100% methyl ethyl ketone (MEK) in a lint-free, durable rayon nonwoven wipe — aerospace approved for composite surface prep, metal bond, edge seal applications, and removal of tank sealants including PR-1422 and PR-1435. The reusable canister format delivers consistent wipe saturation, reduces solvent consumption and VOC emissions, and eliminates the cross-contamination risk of shop rags. Meets or exceeds AMS3819C and BMS15-5 aerospace specifications. Refill rolls available (p/n 2812-100-69-R) to reduce cost and waste.
Sold individually (100 wipes/canister). Refill rolls available separately.

Available Solvents in the Clean & Prep Series
Techspray Clean & Prep Wipes are available in four aerospace-approved solvents. Choose based on your specific surface prep or cleaning application:
- MEK (this product) — Composite surface prep, metal bond, edge seal, and removal of uncured resins and tank sealants (PR-1422, PR-1435)
- MPK (2813) — Composite surface prep, uncured epoxy removal, and printing ink clean-up
- Acetone (2811) — Oils, greases, adhesives, wet epoxy, and paint overspray; VOC exempt, fast evaporating
- IPA 99% (2810) — Dust, debris, light oils, and fingerprints for paint surface prep

Frequently Asked Questions
What is MEK used for in aerospace surface prep?
Methyl ethyl ketone (MEK) is used in aerospace and defense manufacturing for cleaning and surface preparation of composite structures, metal bond assemblies, and edge seal applications. It is particularly effective at removing uncured resins, PR-1422 and PR-1435 polysulfide tank sealants, and other aerospace adhesives and coatings during layup and assembly. MEK is a stronger solvent than IPA or acetone for these specific applications and is specified by name in many aerospace process specifications.
Why use pre-saturated wipes instead of saturating shop rags?
Pre-saturated wipes deliver consistent solvent loading on every wipe, eliminating the variability of manually saturating shop rags. This ensures process repeatability, reduces solvent waste and VOC emissions, and prevents cross-contamination — each wipe is new and clean. The canister format also reduces accidental spills and worker solvent exposure compared to open solvent containers. For aerospace applications where process documentation and repeatability are critical, pre-saturated wipes are the preferred format.
Are refill rolls available for the canister?
Yes. Refill rolls (p/n 2812-100-69-R) are available separately and fit the reusable canister, reducing per-wipe cost and packaging waste. The canister is designed to be reused with refill rolls for ongoing production use.
What aerospace specifications does this product meet?
Techspray Clean & Prep Wipes meet or exceed AMS3819C (SAE Aerospace Material Specification for cleaning cloth) and BMS15-5 (Boeing Material Specification for cleaning solvent). These specifications are commonly required by aerospace OEM process documentation for surface prep operations on composite and metal bond assemblies.
