D1 Adhesives in this class are used inbonding in low humidity environments and without significant Climatic variations in humidity and temperature. They are suitable for use in making mobable furniture and upholstery artifacts.

[D2 Adhesives in this class provide stable bonding in indoor environments with high humidity, with variable and occasional water action. Ideal for kitchen and bathroom cabinets. D3 Adhesives in this class are suitable for bonding under varying climatic conditions. They are suitable for bonding artifacts subjected to moisture and water for short periods of time, such as window frames and doors.
