Brief Introduction

Colour coated coil is a product made from hot-dip galvanised sheet, hot-dip aluminium zinc plated sheet, electro galvanised sheet, etc., which is pre-treated (chemical degreasing and chemical conversion treatment) and then coated with one or several layers of organic paint and subsequently baked and cured. Because of the coating of different colours of organic paint coloured steel coil and so named, referred to as colour coated coil.

The use of hot-dip galvanised steel strip as the substrate of the colour coated steel strip in addition to the zinc layer protection, the zinc layer on the organic coating plays a role in covering and protecting the steel strip to prevent rust, the service life of the steel strip is longer than the galvanised strip, about 1.5 times.

Colour Coated Coil Usage

Colour coated coil has light weight, beautiful and good anti-corrosion properties, and can be directly processed, the colour is generally divided into grey and white, sea blue, brick red, mainly used in advertising, construction, home appliance industry, electrical appliances industry, furniture industry and transport industry.

The coatings used for colour coated rolls are selected according to the use of different environments with suitable resins, such as polyester silicone modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on. Users can choose according to the use.

Coating Structures

Type of coating structure

• 2/1: Coat upper surface twice, lower surface once, bake twice.

• 2/1M: Coat upper and lower surfaces twice, bake once.

• 2/2: Top and bottom surfaces are coated twice each and baked twice.

Usage of different coating structures:

• 2/1: The corrosion resistance and scratch resistance of single layer back coating is poor, but it has good adhesion, mainly used for sandwich panels.It is mainly used for sandwich panels;

• 2/1M: backcoat with good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer compression moulding panels.

• 2/1M: good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer pressboards and sandwich panels.

• 2/2: double-layer backing paint with good corrosion resistance, scratch resistance and processability, mostly used for single-layer pressboards, but with good adhesion.

Most of them are used for single-layer moulding board, but its adhesion is not good, and it is not suitable for sandwich board.

Valspar (Sherwin-Williams) PVDF PPGL Introduction 

High-performance coatings for metal building exteriors, such as Fluropon 70% PVDF, have become the industry standard for preserving metal architecture. Qualities such as film integrity, durability, and resistance to UV rays are just a few of the reasons PVDF coatings have risen to the top.

1. Adhesion Quality

PVDF coating systems offer excellent overall adhesion because of the high-quality resins used in the formulas. Resins hold the entire coating system together, ensuring strong adhesion to the substrate and top coat.

2. Film Integrity

Film integrity refers to uniformity in a coating, meaning the coating resists cracking and general defects. PVDF coatings lead the field with superior film integrity due again to the use of high-quality resins. For example, Sherwin-Williams Coil Coatings uses a proprietary mix of resins that allows our 70% PVDF Fluropon coatings to provide excellent film integrity.

3. Abrasion Resistance

Abrasion resistance is important not only on finished metal building products, but also while metal panels are in transit from shops to building sites. The nost reliable coatings on the market are formulated to resist different kinds of abrasion that can occur before and during the installation process. These types of abrasions include marring, scratching, etching and other damage that can occur frequently at manufacturing facilities, on the road and at job sites.

4. Durability

With durability being top of mind, it’s important for architects, engineers and designers to have architectural metal panel coating options they can rely on. The architectural coating is the first layer visible on the building’s exterior and is ultimately responsible for its appearance and durability. This means the coating has the toughest job of all and must act as the first line of defense against harsh elements, including hail, acid rain, UV rays and much more. Luckily, PVDF Coatings are designed to ensure the durability of a structure and to provide exceptional resistance to harmful elements in high-stress environments.

5. Chalk and Fade Resistance

When metal is left untreated or uses coatings that aren’t made to resist the sun’s damage, UV rays can create a “chalky” film atop metal architecture. Coatings that clad metal building products have the unique challenge of protecting buildings against an array of weather conditions, specifically offering a waterproof barrier that stands up to UV rays, humidity, acid rain and corrosive salt.

Ultimately, architectural coatings provide superb protection against harsh outdoor elements and abrasion once they’ve been applied to panels. Through rigorous and continuous testing, coating manufacturers have created durable PVDF coating formulas that withstand the test of time, weather, and general wear and tear with the ultimate goal of preserving metal architecture long into the future.

DECHO building colour steel plate can meet the need to use colour steel plate as raw material for building. Decho Building Materials colour steel plate is mainly processed into, for example, colour steel corrugated board or colour steel composite sandwich board after our colour steel plate is widely used in the construction of airports, freezers, steel plants, warehouses, and other industrial buildings and commercial buildings, such as the roof of the colour steel tiles, colour steel plate sandwich walls and doors.
