Detailed product description

Product Introduction

Tianshan TONSAN® 1591 silicone rubber flat sealant is a black-gray, instant sealing type, medium viscosity, high strength, high elongation, excellent heat aging resistance and engine oil resistance sealant. It is suitable for flat sealing of various parts of the engine, and can be applied by machine or manually.

Product Application

TONSAN® flat seal series products are liquid before solidification and can fully fill the flat gap. Its unique sealing mechanism has better oil resistance, medium resistance, vibration resistance and aging resistance, fundamentally improving Sealing reliability, replacing gaskets to eliminate hidden dangers, and can also be mixed with gaskets included in the size chain to enhance the sealing effect. While ensuring the sealing effect, different working conditions in equipment maintenance require different characteristics of sealing materials.
