Germa-Tech Matting Agent is used to reduce the brightness of the paint. Good matting ability providing a smooth paint film. Suitable for both 1k and 2k paint systems.
| Ratio by volume | 2K Top Coat or Clear : Matting Agent - Satin 70% : 30%; Matt (egg shell) 50% : 50%; Extra Matt 30% : 70%. 1K Base Coat : Matting Agent - Satin 85% : 15%; Matt (egg shell) 50% : 50%. |
|---|---|
| Notes | The Matting Agent additive does not affect the amount of hardener required. Base the amount of hardener (as per product TDS you are using) on the amount of top coat/colour used before you added the Matting Agent into the mix. Worked example from the sheet: Satin 700ml top coat + 300ml matting agent + 350ml hardener; Matt (egg shell) 500ml + 500ml + 250ml; Extra Matt 300ml + 700ml + 150ml. Application: refer to the technical data sheet (TDS) of the matching products for proper application. |
No drying schedule is printed on the source sheet.
| Density | approx. 0.97 (relative density, water = 1) — estimated from the Safety Data Sheet; not separately measured |
|---|---|
| Equipment cleaning | Clean guns and equipment immediately after use with gun wash or a solvent cleaner. Never let mixed 2K product start to cure in the gun — once it kicks, no solvent will save it. |
| Storage life (unopened) | Up to 36 months unopened — SUBJECT TO correct storage: a cool, dry place below 20 °C, out of direct sun. Heat is the biggest killer of paint in the tin: stock stored or transported in hot vehicles, tin sheds, shipping containers or direct sunlight loses life fast whatever the date on the tin, and that is where most premature failures start. Storage life is an optimal guide, not a promise that survives a hot shed. |
|---|---|
| Once the seal is broken | Once the seal is broken the clock starts, and how you store it sets the pace. This product: 90 days once the seal is broken, resealed tight — then discard. All hardeners: 14 days once opened — then discard. Hardener is sealed without air; the moment air enters it starts to deteriorate. A part-used tin resealed tight lasts the 14 days; a loose lid does not. |
| Storage | Store indoors in a cool, dry place below 20 °C, out of direct sunlight, with the lid sealed tight after every use. Never store or transport in heat — not in a tin shed, a shipping container, a hot van or a sunlit rack. |

This is an ancillary — it supports the steps above rather than forming a layer of its own.
Standard inclusions are controlled: each note applies to every product in its named set, enforced at build. They cannot drift onto some sheets and off others.
| DEFECT | WHAT YOU SEE | WHY IT HAPPENED | FIX |
|---|---|---|---|
Dirt and dust inclusion | hard specks sitting in or under the cured film, felt with the back of the hand before they are seen | dust pulled in during application - panel not tacked off, static on plastic parts, dirty booth filters, contaminated air, overalls or gun, or crystallised additive poured straight from the tin | surface nibs come out after cure with P1500 working to P3000 then polish; anything embedded through the film has to be sanded and refinished |
Chalking | a dry, powdery, chalky surface that dusts off on a cloth and will not polish up | resin at the surface breaking down or over-matted film - too much matting agent for the product, an Extra Matt used in clear, or long weathering on an under-protected film | sand the chalked film back and refinish with the correct matting level and full hardener |
Mottling | light and dark patches or streaks through a metallic or pearl, often following the direction the gun travelled | the metallic flake has not settled evenly - basecoat laid on too heavy, film over 25 µm, flash between coats skipped, gun pattern or pressure wrong, or the reducer too fast for a hot day | if the clear is not on yet, re-flash and lay a controlled final coat to even the flake; once cleared, sand back and respray the basecoat |
Soft film and slow cure | the film stays soft, marks under a fingernail or a mask edge, clogs the paper when sanded and will not polish up | wrong or short-measured hardener, mixing beyond pot life, spraying too cold, bake cut short or started before the flash was finished, or a drying additive used where a hardener is needed | give it a full bake cycle and re-check; if it is still soft the film has to come off back to a sound layer and be redone with the correct mix |
Poor hiding | the undercoat, repair or featheredge is still visible through the colour after the stated number of coats | an inherently transparent colour, a primer colour too far from the topcoat, chasing coverage with extra thin coats instead of correct film, or basecoat over-reduced | on high-brilliance and poor-hiding waterborne colours add 5% WB3075 then WB3041PLUS; otherwise let it flash, correct the ground colour and rebuild - do not just keep stacking coats past the film limit |
