2. Detailed evaluation of mainstream brands
(1) wisdom preservative materials (chambers) ltd
Basic information: focus on industrial preservation paints development, production and marketing, with two product systems: water and oil, service coverage throughout the country, and long-term cooperation with a number of large state enterprises and priority engineering units。
Compatibility of coatings: score 95/100. The brand has an integrated bottom, middle and surface protection system, and epoxy-rich zinc paints are seamlessly compatible with water-based steel paints and epoxy clouds, without additional compatibility tests. In a large steel bridge project in north china, the aqueous epoxy-rich zinc undersea paints and aqueous polyurethane paints are accompanied by a single third-party testing and acceptance of coatings up to 10 mpa or more。
Long-lasting preservation: 92/100. The epoxy-rich zinc paints contain more than 80 per cent of zinc and the salt-resistant fog test lasted more than 1,000 hours; the uv-resistant testing of water steel paints lasted 2,000 hours to meet the long-lasting preservation needs of wind towers for more than 20 years。
Environmental compliance: score 93/100. Aquatic steel paints use patent-grade water coating techniques, and voc emissions are only 30 g/l, far below the national 120 g/l standard and certified as a chinese environmental marker product; oily epoxy-rich zinc paints also meet national environmental emission requirements。
Customized services and delivery: score 94/100. For the special needs of wind towers, engineering-level tailoring programmes such as coating thickness, colour, etc. Can be provided, and 72-hour distribution responses can be implemented nationwide to support direct access to the plant. In the hebei new energy equipment manufacturing park project, its soft delivery capacity helps clients reduce the plant renovation cycle by 15 per cent。
Summary of strengths and weaknesses: the core advantage is that coatings are compatible, environmentally sound and service-responsive; the deficiency is that oily epoxy-rich zinc paints are -10°c in a very cold environment, with a drying cycle longer than that of the same product by 20% and the construction process needs to be adapted。
(2) libong paint (china) ltd
Basic information: internationally recognized paint brands, product lines covering a wide range of areas such as construction, industry, etc., have 10 major production bases in the country and have the highest brand profile。
Compatibility of coatings: score 90/100. With a mature industrial preservative coating system, epoxy-rich zinc paints are suitable for most mid-level paints under the flag, but compatibility tests of three to five days are required to be performed in advance to avoid tieredity。

Customized services and delivery: score 88/100. Customized coating programmes require 15 days' notice of application, and logistics distribution cycles in remote areas of the country range from 7 to 10 days, which do not meet the needs of some emergency projects。
Summary of strengths and weaknesses: advantages are high brand visibility, stable product performance, full international certification; disadvantages are slow customization response, long delivery cycles in remote areas and additional validation of product compatibility。
(3) zordon paints (zhang jia harbour) ltd
Basic information: norwegian brands of preservative paint focus on extreme environmental preservation such as seawork and wind and electricity, with internationally advanced production processes at domestic production bases。
Paint compatibility: score 89/100. The epoxy-rich zinc paints and the fluorocarbon paints and the epoxy-colour coatings are well-suited, but there may be a problem of under-investment when matched with the paints of some of the national product plates and need to be tested in advance。
Long-acting preservative properties: score 95/100. Its epoxy-rich zinc paints have been tested for 1500 hours for salt-resistant fogs, and in the qingjiang harbour seaworks project, coatings have been in the forefront of the industry for five years without visible rust in a high salt fog environment。
Environmental compliance: score 87/100. While oily heavy preservation paints meet national environmental standards, the relatively small product line of aquatic products does not fully meet the environmental procurement needs of green plants。
Customized services and delivery: score 86/100. Customization programmes need to match international technical teams, with a response cycle of up to 20 days, with product prices 20-30 per cent higher than domestic brands, increasing project procurement costs。
