PROBLEM TO BE SOLVED: To provide a room temperature curable polyorganosiloxane composition which has less deterioration in hardness of a hardened product under high temperature and high humidity, and good adhesiveness to various base materials.SOLUTION: A two-component room temperature curable polyorganosiloxane composition is composed of a main agent composition (A) and a hardener composition (B). The main agent composition (A) contains polyorganosiloxane having a resin structure represented by the average unit formula (c): (RSiO)[Si(OH)O], at a predetermined ratio. The hardener composition (B) contains: (d) a trifunctional or tetrafunctional silane compound, or partial hydrolysis condensate thereof; (e) a first amino group-containing silicon compound; and (f) a second amino group-containing silicon compound. |
