Minchem Ltd (ACCS Ltd) VE55
- Chemical Family
- Novolac Vinylester
Minchem VE55 is a high-performance vinyl ester-based acid-resistant material designed to provide maximum resistance to aggressive chemical environments. It is typically provided in a two-component format comprising, a vinyl ester solution and a catalyzed filler powder, which can be altered, with varying granulometry to suit the required thickness and application.

- Safety
Adequate ventilation must be provided whilst work is in progress and is compulsory for closed or indoor applications.; The instructions on storage, fire and explosion are to be observed.; No releases to the sewers or drains are to be permitted under any circumstances.; Ventilation is required with special consideration for enclosed or confined areas.; Air movement must be designed to ensure turnover at all locations in work area and adjacent areas to avoid build-up of heavy vapors.

- Pot Life
at 20°C - 25mins; at 30°C - 20mins; at 40°C - 10mins; An initial set occurs approximately 4hours after mixing, light foot traffic permissible after 12hours and with a full chemical cure occurring after 5-7days.; The materials should never be exposed to water, steam or chemical environments before a full chemical cure is completed.; Do not mix more material than required by pot-life.; It cannot be reconstituted. Never add unapproved materials to the mix, in particular water.; After mixing spread out on to the surface to avoid self-generated heat.; Large mixed volumes that are not thinned will flash set, becoming extremely hot and producing smoke.
- Advantages
Provides resistance to the majority of concentrated oxidizing acids, such as nitric acid to 50%, sulphuric acid to 75%, hydrochloric acid to 36%, phosphoric acid to 85%, sodium hydroxide to 50% and sodium hypochlorite.. It is also resistant to hydrofluoric acid (with carbon-based filler) and a large number of concentrated alkalis and salts.
- Application
Using an inclined mixer or paddle mixer, place the powder in mixing vessel and add the solution.; Mix thoroughly for at least 3 minutes; the powder will 'wet' out to a mortar. For coatings, apply by paint brush, roller or float/trowel depending on thickness/application desired.; Apply until a smooth coating has been established without allowing the materials to form into pools or flood the area.; Leave to cure, and then apply second coat 12- 16 hours but not later than 48 hours after the first, to even off the finish and give an attractive gloss.; To aid adhesion of the second coat, the application of a fine quartz scatter before full cure is recommended to provide a key for subsequent layers.; Where necessary, enhanced strength and durability of coatings can be achieved through the addition of a fine weave glass matting material.; To provide anti-slip facilities to the coating it is recommended that the mixed product is allowed to cure for 1 hour before application of an anti-slip scatter material.; As such, examination of the lining should be made after the second coat has been applied to ensure complete coverage.; Vinylester-based materials also stay tacky for a number of days after installation.; Prevent access during this time or apply a light scatter of inert material to prevent footmarks or the adherence of dirt.; For mortars, application should be made with either float or trowel to all jointing surfaces to ensure a complete chemical barrier.; For all trowel/float applications, regular brushing of tools with solvents ensures a smooth (non-drag) finish.; However, do not apply too much solvent or this will lead to blistering of the vinylester finish.; All tools and equipment should be cleaned off with solvents and damp cloths to ensure their continued use.

- Typical Uses
It is one of the most corrosion-resistant materials on the market.; It is an extremely flexible material that can be installed as a coating, membrane, mortar, screed or concrete, depending on the coarseness of the powder component.; This versatility allows for its installation in a number of applications such as; general tiling/masonry work, trenches, pits, floors, walls, plinths, tanks and storage areas.
