Aluminum honeycomb panel is a very common decoration material. It can be made into a panel with light weight, high strength and very flat surface. It can be used in structures, cushions, partitions and decorations. It is used in curtain walls, building partitions, Sound-absorbing panels, high-speed

Two-component polyurethane adhesives are adhesives obtained by the reaction of isocyanates and hydroxyl-containing compounds, with their molecular chains containing urethane groups (-NHCOO-) or isocyanate groups (-NCO). These adhesives typically consist of two components: one is the isocyanate compo

The influence of moisture on two-component polyurethane is mainly reflected in the following aspects:1. Reduced reaction speed: Moisture reacts with the isocyanate component, reducing the content of the effective component and affecting the curing speed.2. Reduced hardness: Moisture participates in

The main roles of adding molecular sieves in polyurea waterproof coating are as follows:Removing moisture and impurities:Molecular sieves can adsorb moisture and impurities in the coating, reducing their negative impact on the coating’s performance. This improves application performance, weather res
