1. Core Pain Points in Electronic Potting ApplicationsIn the field of electronic component encapsulation, polyurethane potting adhesives are widely used due to their excellent insulation, weather resistance, and elasticity.However, two major technical challenges are frequently encountered in actual

Efficient Application of 3A Molecular Sieve Activated Powder

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
