Sherwin Tri-A Fluorescent Penetrant for Porous Materials Inspection (TRI-A)

Ceramics and porous materials are an inspection problem; their absorbent surfaces do not lend themselves to conventional penetrant inspection methods. Yet, cracks resulting from forming. drying and processing must be found before a part is shipped.

TRI-A is both a laboratory and a production test material for locating detects in the early stages of ceramic, plastic,and porous part production.

TRI-A is suitable for technical ceramics, electrical insulators. and most plastics, as well as many other porous substances, including powered metals.

TRI-A solution is a "ready-to-use" suspension of yellow-green fluorescent particles and a surfactant-based liquid. It is virtually odorless and nonflammable, with a flash point well above 200"F. TRI·A is an OSHA Class IIIB material.

TRI-A is a nonvolatile fluid with a medium particle concentration.
