EPOXY RUST-PROOFING PAINT EM121 IN BLACK
EM121 is our award-winning Epoxy Mastic paint, suitable for brushing and spraying. It is supplied as a two-component pack, complete with thinner. Equal quantities of components A & B are supplied with each available pack size: the mix ratio is simply 1:1 by volume, plus thinner.
Starter and chassis packs are each supplied with 250ml of thinner. The 6-litre packs and 5-litre custom-colour packs are each supplied with 1 litre of thinner.
Packs are supplied with mixing instructions, including thinner quantities. All colours can be over-painted with single or two-pack products, but EM121 also works on its own as a primer-finisher with no need to be over-painted.
This product is typically very viscous (thick) and requires a correct mixing procedure and thinning with the supplied thinner. Please, therefore, follow the instructions to ensure the best results, and see the links below for more assistance:
” I purchased some EM121 paint a while ago after reading numerous reviews, REALLY impressed with several factors, coverage, lack of mess, no runs, no brush bristles, how long the mixture was useable for and the quality of the results..”

|Thinning||Use only the epoxy thinner supplied, from 5 to 20% max.|
|Application & recoating||Brush or spray.
A second coat or topcoat can be applied any time after approx. 5 hours* with no need to abrade between coats. If recoating or top coating once the first coat has fully cured (after approx. 7 days), lightly abrade first with P320 paper.
* At 20 degrees centigrade. Longer intervals may be required in colder conditions.
|Spraying||Minimum 1.8mm nozzle or an HB (high build) primer set up. Test atomisation on a test panel first. Viscosity will vary, i.e. thicker in colder temperatures. Data correct at 20c.

|Pot life||Pot life is the time from mixing the two components to the point at which the mixed paint is no longer useable. For EM121, you have 2.5 hours of pot life once mixed at 20c – longer at colder temperatures.|
|Shelf life||We recommend storing upside down in a dry place at around 20c. In these conditions, the product has a shelf life of 12 months.
Do not store below 20c as this can affect performance.
|Disposal||Allow any excess mixed paint to cure in your mixing cup and throw it away as dry waste.|
|Cleaning||Clean up with standard thinner or gun wash. Do not thin the paint with standard thinner as this will affect the paint cure.|
|Safety||Use in a well-ventilated atmosphere. Use a respirator face mask when spraying or brushing in an enclosed space. Please see the MSDS (material safety data sheet) in our data sheet area.
Wear suitable protective clothing, gloves and eye protection.
|FAQ’s||How many coats are recommended? We would always recommend 2 coats, this will increase the thickness of the coating offering better protection and removing the chance of missed areas (holidays).
Can I paint over a rusty surface? Yes, EM121 is non-porous so will 100% seal the rusty surface, we would recommend removing all loose material from the surface before painting.
Does EM121 come in colours? Yes, 14 colours are available from stock and custom colours are available (minimum pack size 5ltr kit).
How long before I can overcoat? A second coat or topcoat can be applied any time after approx. 5 hours* with no need to abrade between coats. If recoating or top coating once the first coat has fully cured (after approx. 7 days), lightly abrade first with P320 paper.
Can I paint over EM121 with a cellulose topcoat? Yes, EM121 will accept pretty much every type of topcoat, if I doubt we would recommend testing a small area and watching for any reaction before performing an adhesion test if required.
