Product details

Product Description

MT- D3020 Gen II is a series of hyper-durable powder coatings designed to meet the requirements of AAMA2605. the most demanding architectural specification in the world. MT- D3020 Gen II technology uses innovative fluorocarbon polymer chemistry that is designed to provide maximum gloss and colour retention in service. MT- D3020 Gen II is also designed to provide excellent cosmetic and functional protection whilst exploiting the recognised benefits of powder coatings. MT- D3020 Gen II is a technically and environmentally benign alternative to liquid PVF2 systems. MT- D3020 Gen II is available in a selected range of colours and pearlescent effects and in a subtle low sheen finish.

Pre-treatment

For maximum protection it is essential to pre-treat components prior to the application of MT- D3020 Gen II in accordance with the MT-D Approved Applicator Manual. Aluminium components must receive a full multi-stage chromate conversion coating or suitable chrome-free pre treatment to clean and condition the substrate. Detailed advice should be sought from the pre-treatment supplier.

Application – Cleanup

Below are some recommendations for minimising the risk of cross contamination of MT-D3020 Gen II with powders based on other chemistries such as polyester:

If possible, use a dedicated spray to waste booth if not reclaiming.

Ensure thorough cleaning of spray booth, duct work, cyclone (if within system) and all powder application equipment (guns, hoses, pumps, hoppers, etc) before and after applying MT-D3020 powders.

Clean wet rags should be used for a final wipe down on the inside of the booth and feed hopper.

When returning to application of polyester powders after a MT-D3020 run, shoot foam blocks through hoses and flush guns with next powder to remove any traces of fluorocarbon, and spray this powder to waste before reclaiming.

If reclaiming powder after MT-D3020 run, check reclaim powder for contamination before reuse.

Where possible isolate the application of MT-D3020 from other production eg. use at weekends or on night shift when no other production is taking place.

Operators should wear dedicated protective clothes for MT-D3020 application. At other times, these should be stored in sealed containers.

MT-D3020 can be stored along with other powder so long as it is in sealed containers.
