What is the difference between solvent-free epoxy and conventional epoxy?
Although both solvent-free epoxy coatings and conventional solvent-borne epoxy coatings belong to the epoxy system, they differ fundamentally in terms of environmental friendliness, application processes, coating performance, and scope of use. This paper conducts a comparative analysis to highlight the core differences between the two in terms of formulation, environmental compatibility, construction safety, and performance characteristics.

Why are industrial sealants so important? What are the main types?
Industrial sealants are chemical products used to create seals between surfaces, preventing the leakage of air, gases, and liquids, guarding against external contamination, and filling gaps and voids in industrial equipment and products. Next, we will introduce the common types of sealants and their advantages in industrial applications.

Air bubbles and pinholes during grouting—causes and solutions
The presence of air bubbles during the potting process can directly affect the product’s sealing performance, insulation properties, and visual quality (such as dents and voids caused by bubbles), and may even lead to subsequent leakage if the bubbles rupture. So, why do air bubbles form in the first place?
