You can apply Selemix Aqua to various coatings and substrates such as: The hardener for both 8-110 and 8-111 is Selemix Aqua 9-110 Direct Hardener. This is unlike other epoxy systems you may have used before. Selemix Aqua requires users to buy the base and hardener separately.
Selemix Aqua is a polyurethane coating that is a two pack – meaning it has a base and a hardener. This saves contractors time, cost and keeping restricted access times to a minimum.
A major benefit of this system is the lack of a primer. So, if a specification requires a matt finish, you can use Selemix Aqua 8-110 Matt. However, Selemix Aqua does not require a primer. EA9WB Coating was produced as a semi gloss or high gloss finish so Selemix Aqua 8-110 is an ideal replacement. 8-111 relates to the replacement of 3M’s primer. Originally, 3M’s EA9WB Primer was always produced in a matt finish. The Selemix Aqua system consists of 8-110 and 8-111 with finishes gloss and matt respectively. All the old 3M products such as EA9WB, EA9WB Primer, and EA5WB were all water based and used on London Underground. The testing on Selemix Aqua has been extensive for this reason. Waterborne is different to water based as some solvents are still used. Selemix Aqua system does however have these tests under it’s belt as it is a waterborne product. This is as it doesn’t have the smoke inhalation or toxicity of smoke testing certified as yet. However, Selemix Direct cannot currently be used on London Underground. This covers BS476 Part 6 and 7: The Surface Spread of Flame and Propagation of Fire. Selemix Direct now certified for BS 6853. Selemix Direct system has been fire tested to reach the rigorous standards required for the UK rail system. Introducing Selemix Direct & Selemix Aqua They have very good adhesion properties to various types of surfaces. Both of these systems are primer and topcoat systems in one. These are in the form of PPG Selemix Aqua, Selemix Direct. Working closely with PPG Selemix, TfL (Transport for London) and London Underground Limited, Promain have now come up with some solutions to the lack of 3M coatings. The Future of APR London Underground Paints Unfortunately, now they are all gone, and we need to find replacements. Specified applicators still believe these products are available. Metal plates on trains, products for fuel tanks or water containers on the underside of trains need protection. Contractors still need paints for rail rejuvenation. These companies are now calling Promain’s technical team looking to purchase 3M EA9WB, 3M EA5WB, or for example Copon Hycote. This entailed fabrication companies within the rail industry without suitable specified coatings for inside or outside trains, or underneath trains such as bogies. To find suitable substitutes expensive testing, certification and worrying time frames were needed to be allowed for. Unfortunately, due to minimal notice given to the market, specifiers had just 3 months to arrange alternatives. Since the closure, 3M’s paint specifications are still found across the rail and infrastructure sector. 3M’s heads in America therefore chose to abandon all paints except a few international pipeline products. However, 3M saw their paints and coatings sector proving to be not as successful as they hoped.
As a result, this opened up the specialist coatings market to the brand. 3M being a global success brought these companies in the early 80’s and 90’s. Prior to 3M buying out these original companies, they were UK brands that formulated fantastic paint coatings that were unsurpassed. The 3M side of their products were formulated by E Wood, Thortex and Copon. Promain have worked closely with PPG and TfL to find replacement systems for contractors. This has mainly effected the rail industry, London Underground and also steel coatings industries. The paint industry has now been left with a gaping hole in the market. Since the closure of 3M’s paint and coatings factory in Northallerton in the final quarter of 2017, all the stock that was produced has now been diminished.
