Silkon PS-500

Silkon PS-500 PG is a Pourable version designed for use in horizontal joints. Adhesion is excellent to most common building substrates. The product is particularly recommended for sealing horizontal structural expansion joints in most civil engineering structures like building superstructures, subways, basements, floors and reservoirs.

Product usages and advantages 

• Forms a tough elastic rubber-like seal.
• Accommodates continuous and pronounced cyclic movement.
• Excellent adhesion to most common substrates.
• High resistance to ageing influences, physical damage and climatic extremes.

Description

Silkon PS-500 is a two part joint sealant based on a liquid polysulphide polymer. It is supplied as a 2.5 L pack containing a base component and curing agent in the correct proportions which, when mixed together, cure to form a tough rubber-like material. When cured, the sealant exhibits excellent adhesion to most surfaces including concrete, aluminium and stainless steel. Priming is recommended for porous surfaces and for some specific surfaces and applications.

Silkon PS-500 is available in two grades. Gun grade for general applications and Pouring grade for joints in horizontal surfaces. Silkon PS-500 is particularly recommended for use in high rise buildings and other applications where access for subsequent maintenance will be difficult and the risk of early movement failure must be minimised. It is also suitable for sealing joints in subways, basements, retaining walls, reservoirs and brickwork joints.
