Protective Basecoat Powder Coating

Protective Basecoat Powder Coating About

Product Description

MT-A2204 basecoat comes in an array of metallic finishes, which offer enhanced exterior durability with the application of a super-durable polyester clearcoat. These advanced systems incorporate proprietary technology to protect and extend the life of these metallics. These MT-A2204 basecoat powders are moisture and stain resistant, chemical and chip resistant durable, and built to last in the most challenging environments.

Test Conditions

The results are based on mechanical and chemical tests which (unless otherwise indicated) have been carried out under laboratory conditions and are given for guidance only. Actual product performance will depend upon the circumstances under which the product is used.

Substrate	Steel panels, Aluminium
Pretreatment	Bonder (WH/60/OC) iron phosphate, Bonder (722/W/OF)
Film thickness	70 m
Cure schedule	10 minutes 200C

Pre-treatment

Steel surfaces to be coated must be clean and free from grease. For maximum protection it is essential to pre-treat components prior to the application of MT-A2204 basecoat. Iron Phosphate and Zinc Phosphate of ferrous metals improve corrosion resistance. Aluminium parts require a chromate conversion pre-treatment.

Application

MT-A2204 basecoat powders can be applied by manual or automatic electrostatic spray equipment. Tribo application is not recommended. It is recommended that for consistent application and appearance product be fluidized during application. MT-MW188I must be fully cured otherwise there may be a loss of metallic effect or discoloration of the clear topcoat. MT-MW188I is not stabilized for direct gas fired ovens.

All coated pieces should be handled with clean lint free gloves.

Parts should not be stored in an environment with high humidity.

Clear coat should be applied as soon as possible after metallic application (maximum time between coats is 8 hours)

Parts should not be passed through a pre-treatment process prior to application of the clear coat Despite the fact that MT-MW188I is a bonded metallic it is not recommended to recycle the powder.

Exceptional Corrosion and Impact Resistance

Engineered for longevity, this basecoat withstands up to 1000 hours in salt spray (ASTM B117) and endures impacts greater than 50 kgcm. Its robust protection helps prolong the service life of metal structures even in challenging industrial settings.


Versatile Application and Color Options

Compatible with a variety of surfaces, the powder can be applied using electrostatic spray technology. Choose from a wide palette including black, grey, brown, blue, red, or request a custom shade, all available with different gloss levels for tailored surface finishing.


Safe, Easy Storage and Application

Non-toxic after curing, this powder offers safety in use and handling. The product retains its quality for 12 months when stored sealed in a cool, dry location. Convenient 20 kg HDPE bags or drums make it suitable for large-scale operations.
