PPG Semco
PPG Aerospace has decades of experience down packaging specialty chemicals for aerospace, electronics, and general industrial applications from bulk formats to custom sizes. The Semco® name covers a range of dispensing and packaging equipment, suited to pack a variety of materials including adhesives, sealants, coatings, lubricants, and other critical assembly fluids.
At Silmid, we have access to the full complement of Semco® product, and can assist our diverse customer base with making sure they have everything they need, in the size they require, at the best value.
To make things easier, all Semco® part numbers are included in our product description, and so are able to be searched for on the website.
The Semco® brand consists of a number of sealant dispensing solutions. Whatever your application requirements, there is a Semco® applicator gun to suit.
Semco® needles are available in a variety of shapes, sizes and gauges to suit many applications, used in conjunction with other Semco® products.
Semco® disposable plastic cartridges are available in low or high-density natural polyethylene. Each from their range of sizes are fit with 1/4" NPT female thread dispensing orifice.
Semco® sealant removal tools are made from celcon and glass-filled nylon. Adept at removing aerospace sealants and adhesives, they come in 11 different shapes and sizes.
Semco® flange caps and tip caps are to be used in conjunction with additional Semco® products, including syringes, needles, plungers and tips.
There are three different Semco® pistons to meet your application needs: A micro-interference fitting P-piston, a low friction piston (LF), and a non-interference fitting piston (NI).
Semco® hybrid syringe barrels are moulded of polypropylene reduce air-entrapment by eliminating the sharp corners found in most traditional syringes.
Quick Access
PPG Aerospace Authorized Distributor

PPG Semkit Mixing
The mixing of a Semkit®️ by other means, such as with a drill adapter, may compromise the performance properties of the sealant and void the warranty.
When mixing a PPG Aerospace sealant Semkit®️, always follow the directions as dictated on the product packaging. The recommended mixing instructions are tested and validated to ensure that the sealant performs as intended and meets all specification requirements.
Instructions are provided for hand mixing (including Semco Model 285 mixer), or for automatic mixing with a Semco Model 388, Model 1088 or Model 1188 machine mixer.
Machine mixing and hand mixing are the only industry recognized methods for mixing sectionalized containers (Semkit®️) as referenced in SAE AIR4069 and Boeing BAC5000.

Mixing outside of these controlled and validated procedures has the potential to alter the sealant performance or even damage the sealant itself.
Testing shows that mixing with a drill adapter has several definitive detrimental effects on the sealant: Uncontrolled mixing speed will excessively heat the sealant and greatly reduce the working time of the sealant, and will decrease the extrusion rate below specification-required values. The high torque and shear induced with a drill may also damage certain raw material ingredients in the uncured wet sealant, irreversibly degrading the anti-sag properties of the wet sealant, or the density of the cured sealant.
Low density sealants are especially affected by drill mixing. Any of these negative effects may cause the sealant to perform outside of specification requirements,

Low density sealants are especially affected by drill mixing. Any of these negative effects may cause the sealant to perform outside of specification requirements,
and will therefore void the certification and/or warranty. Mixing with a drill adapter also presents significant safety concerns, as there have been documented cases of user injury when mixing a Semkit ®️ with a drill.
