AI Technical Summary

Benefits of technology

This patented new type material for paints used in construction works solves problems associated with traditional materials like plaster boards due to their high volatile contents (VOC) released during manufacturing processes. Instead, this new material combines certain technical feates: 1), controllable pigment size without adding any extra ingredients, reducing waste and improving durability while maintaining good appearance properties, 2). Using an aqueous solution instead of conventional solutions containing harmful chemical substances, resulting in reduced pollution levels and improved safety standards compared to previous methods. 3） By combining different types of resin components together, these materials have better hiding power and wettabilty when applied over coatings made from various substrates.

Problems solved by technology

The technical issue addressed by this patented technology relates to developing an effective chemical solution used during coating processes where colored paints can form strong adhesion between different materials like glasses and plasterboards due to their unique properties such as high hydrophobicity and resistance against moisture penetration.
