Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of polyurethane anti-corrosion coatings, it is recommended to prioritize confirming key technical parameters such as solid content, salt spray resistance time, and adhesion level of the product to ensure its suitability for specific corrosion scenarios such as marine environments or chemical equipment.
  • When selecting suppliers, priority should be given to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support. Such suppliers can usually provide more stable coating performance solutions.
  • In outdoor scenarios such as bridge steel structures or tank outer walls, attention should be paid to the weather resistance and UV stability of coatings. It is recommended to choose polyurethane anti-corrosion coating products with relevant practical application cases.
  • Different substrates (such as concrete or metal) have significant differences in compatibility requirements for coatings. When purchasing, suppliers should be required to provide targeted technical specifications and construction guidance documents.

Knowledge Base

Q

Polyurethane anti-corrosion coatings have many significant characteristics. Firstly, it has excellent chemical corrosion resistance, which can effectively resist the erosion of various chemical substances such as acid, alkali, salt, etc., providing reliable protection for the substrate. Secondly, it exhibits excellent adhesion and can tightly adhere to various substrate surfaces without easy detachment. Furthermore, its fast drying speed helps to improve construction efficiency.

Q

  Modified polyurethane anti-corrosion coating is a two-component elastic coating, with component A consisting of hydroxyl containing elastic polyester and epoxy resin as base materials, defoamers, and related additives. The B component is an adduct of polyisocyanates and polyols. Modified polyurethane anti-corrosion coating is achieved through the ternary copolymerization and chemical modification of polyurethane, which changes and improves the performance of polyurethane anti-corrosion coating.
