The mainstream classification of zinc paste and the types suitable for industrial scenarios are as follows:
1、 Mainstream classification of zinc paste
Divided by Zinc Powder Content
Low zinc type zinc paste: with a zinc content of 30%~50%, it focuses on low cost and only meets basic rust prevention needs.
Medium zinc type zinc paste: with a zinc content of 50%~80%, it balances protection and construction convenience, and is the most widely used product in the market.
High zinc type zinc paste: with a zinc content of over 80%, it has extremely strong anti-corrosion performance and is suitable for high corrosion extreme working conditions.
Divided by dispersing solvent
Water based zinc paste: using water as the dispersing medium, low VOC, environmentally friendly, odorless, and free from flammable and explosive risks.
Solvent based zinc paste: using organic solvents as carriers, the coating has strong adhesion, excellent outdoor weather resistance, and is suitable for wide temperature environments.
Divided by core functions
Anti rust special zinc paste: mainly used for basic anti rust protection, mostly for daily maintenance of ordinary metal components.
Conductive and Thermal Conductive Zinc Paste: A high zinc content formula specifically used for conductive and thermal filling of electronic and electrical components.
High temperature anti sticking zinc paste: added with high temperature resistant additives, can withstand high temperatures above 1000 ℃, avoiding component adhesion and sticking due to high temperatures.
Divided by curing characteristics
Self drying zinc paste: It naturally dries and solidifies at room temperature without the need for additional heating or baking, and has a low construction threshold.
Baking curing zinc paste: It needs to be baked at a high temperature of 180 ℃~220 ℃ to form a film, resulting in higher coating hardness and longer protection life.
2、 Core types suitable for industrial use
General industrial rust prevention scenario: Zinc based solvent self drying zinc paste is preferred, balancing cost and weather resistance, and suitable for outdoor daily maintenance of the vast majority of steel structures and construction machinery.
High corrosion industrial scenario: Choose high zinc solvent zinc paste, suitable for strong corrosion environments such as coastal high salt spray and chemical workshops, with a corrosion resistance life of over 5 years.
Indoor industrial scenarios with strict environmental requirements: choose water-based zinc paste, low VOC, odorless, no flammable or explosive risks, suitable for metal component construction in enclosed workshops.
High temperature industrial assembly scenario: Choose high temperature anti sticking zinc paste, which can withstand high temperatures above 1000 ℃, and is used for high temperature thread and bearing assembly of industrial boilers and heavy machinery.
Electronic and electrical industry scenario: Select high zinc conductive and thermal conductive zinc paste, fill metal gaps, improve component conductivity and thermal conductivity, and adapt to precision electrical equipment production and maintenance.
Batch processing scenario for factory prefabricated components: Choose baking cured zinc paste, which has high coating hardness and strong adhesion, and can greatly improve the long-term protection life of batch components.
