Detailed Description

TWO- PART POLYSULPHIDE SEALANT

DESCRIPTION:

PDSEAL PS 65P is a two-part elastomeric sealant based on a liquid polysulphide polymer which when mixed with accelerator (curing agent) cures by chemical reaction to form a tough, flexible rubber seal. This sealant has excellent Fuel resistance, adhesion to different substrates like masonry, concrete with excellent movement accommodation.

Application Instructions

Joint preparation

The joint surfaces must be clean, dry and free from all contamination. The surfaces should be degreased using the appropriate Cleaner. Primers may be required on some substrates.

Insertion of Backup Materials

A suitable material is closed cell, medium density, cross linked Polyethylene foam, strip or rod.  Ensure constant and correct depth of joint.

 

Masking Tape Application

Masking Tape should be used on both sides of the joint to improve the neatness of the finished seal.

Priming

Apply thin film of kankol porous primer on both sides of the joint with a brush. Allow flash-off of solvent before application of Sealant i.e. surface should be touch-dry. 

 

Mixing

The base and curing agent ratio controls the adhesion, strength and durability of PDSEAL PS-65P

The base and curing agent must therefore be thoroughly mixed.

 

Tooling

Depth Gauge may be used to recess sealant as specified in the drawing.

 

 

Cleaning

After sealing the joint the tools and equipments should be cleaned immediately with kerosene or any other cleaning solvents/thinners.
