Standard durable polyester powder coatings

Surface Finish Options Overview

製品記述

MT-D1036 Gloss is a range of powder coatings intended for use on architectural aluminium and galvanized steel. MT-D1036 Gloss has been specifically formulated without the use of TGIC. As part of the MT-D1036 series of architectural powders, MT-D1036 Gloss gives excellent exterior durability and colour retention and conforms to the requirements of all the major European architectural finishing standards. All MT-D1036 Gloss powders are lead-free and meet the requirements of GSB Florida 1. Qualicoat Class 1. EN12206. and EN13438 (formerly BS6496 &BS6497), and AAMA 2603.

前処理

For maximum protection it is essential to pretreat components prior to the application of the powdercoating. Aluminium components should receive a full multi-stage chromate conversion coating or suitable chrome-free pre-treatment or suitable pre-anodising to clean and condition the substrate. Detailed advice should be sought from the pre-treatment supplier. Galvanised steel requires surface preparation by either multi-stage pretreatment using either zinc phosphate or chromate conversion or controlled sweep blasting. Depending on the type of galvanizing, degassing or use of anti-bubbling additives may be required – follow the procedural advice of the pretreatment supplier. The products may also be used on cast or mild steel. For outdoor use MT-PZ anti-corrosive primer over a correctly prepared substrate is recommended.

Application

Powders can be applied by manual or automatic electrostatic spray equipment. This product should be applied at minimum 60μm. All powders can show small color differences from batch to batch, this is normal and unavoidable. Bonded products have better application properties than blended products (more stable) but attention should still be paid to line settings in order to avoid “marble effect” and changes in aspect after recycling.

Products with different codes should not be mixed even if same colour and gloss. Different substrates (aluminium, steel, galvanized steel…), use of primer, and big changes in film thickness may give a different aspect. Applicators and fabricators are advised to use a single batch for parts that will be assembled together. Differences are more likely with special effect powders. For more information, it is suggested to read the Metallic Applications Guidelines. Clearcoats including tinted clearcoats cannot be applied directly on primers. Only fully opaque shades are suitable for application over primer.

Post application

For specific advice on the suitability of post coating processes such as bending or the use of sealants, adhesives, thermal break, cleaning etc. Please consult us.
