POLYSEAL PS POLYSULPHIDE JOINT SEALANT

Transcription

1 POLYSEAL PS POLYSULPHIDE JOINT SEALANT PRODUCT DESCRIPTION is a two component, low modulus, chemically curing polysulphide joint sealant, developed specifically for dynamic joints. is based on a liquid polysulphide polymer which when mixed with the hardener, cures to form a tough rubberlike seal. exhibits excellent adhesion to most surfaces and has good resistance to many chemicals and weather conditions. is available in both gun grade and pouring grade. The gun grade is suitable for vertical or horizontal applications and is available in a ready to mix, two and a half litre tin containing the base and curing agent in correct proportions. The pouring grade is suitable for horizontal applications and is available in a four litre pack with base and curing agent in separate tins. APPROVALS & STANDARDS BS EN ISO 11600: A1:2011 (formerly BS 4254) BS 5212: Part 1 WRAS BS 6920 Test on effect of water quality ASTM C 920, Type M, Grade NS, Class 25, USE T (Gun Grade) ASTM C 920, Type M, Grade P, Class 25, USE T (Pouring Grade) ADVANTAGES Highly resilient with excellent recovery characteristics. Provides a permanent and uniform water tight seal. Stays flexible won t become brittle or crack due to ultraviolet exposure. Helps prevent uncontrolled cracking by allowing expansion and contraction of the joint during temperature changes. Excellent adhesion to most common substrates. Not harmful to the human environment. Non staining. Can be recycled. Page 1

2 AREAS OF APPLICATION Sealing of movement and construction joints in : Structural floor joints. Airport runways and apron pavements. Industrial warehouses. Chemical Plants. Garages & workshops. Water retaining structures. Sewage treatment plants. Oil and Gas Plants. Note : The products design and performance, its intended use, installation and final confirmation and approval for use, must be provided by the project s Design Engineer and Project Manager.

Joints with cyclic movement should have a width to depth ratio of 2:1. Minimum depth of the sealant should be maintained as recommended below : 10mm for all porous surfaces. 20mm for joints exposed to traffic & hydrostatic pressure. 5mm for impervious surfaces such as metal, glass, etc. Page 2

3 COVERAGE Length of joint in metres filled per litre of. DEPTH (mm) WIDTH (mm) Note : Calculation based on theoretical coverage. Actual material consumption at site will vary depending on the condition of the joints and wastage etc. INSTALLATION PROCEDURES JOINT PREPARATION The joint surface must be clean, dry and free from oils, loose mortar, laitance, release agents and other contaminants. A thorough wire brushing, grinding, sand blasting or solvent cleaning may be required to expose a clean and sound surface. PRIMING Primer should be applied to a clean, dry surface prior to installation of backer rod and/or bond breaker tape. Polyseal Primer is recommended for most common substrates like concrete, tiles, etc. For nonporous substrates like glass & steel, special primer can be applied to achieve optimum adhesion. Where a particularly neat finish is required, apply masking tape on both sides of the joint before priming and remove immediately once the sealant application is complete. BACKING MATERIAL Closed cell polyethylene backer rod should be used to control the depth of the joint sealant to the recommended thickness. Where joint design or depth of joint will not permit the use of backing rod, use a bond breaker tape. PACKAGING 2.5 litre Gun Grade Part A & B in the same pail 4.0 litre Pouring Grade Part A = 4.0 litre pail Part B = 500 ml pail Page 3

4 MIXING PROCEDURES GUN GRADE Supplied in a ready to mix container, with all the components packed in a single tin. The material shall be mixed thoroughly with a slow speed drill ( rpm) fitted with a flat bladed paddle for 23 minutes till a uniform colour and consistency is achieved. Note : Mix one full kit at a time to avoid improper mix ratio. DO NOT PART MIX. POURING GRADE Supplied in a preweighed two parts pack which requires on site mixing. Pour the hardener (Part B) into the base (Part A) pail and mix thoroughly with a slow speed drill ( rpm) fitted to a flat bladed paddle for 12 minutes till a uniform colour and consistency is achieved. Note : Mix one full kit at a time to avoid improper mix ratio. DO NOT PART MIX. FINISHING Once the sealant has been applied, a suitable rounded tool soaked in soapy water can be used to achieve a smooth finish. Any masking tape applied should be removed before the sealant skins over. CLEANING Remove all excess sealant with a scraper. Any spillage can be cleaned using a solvent like Xylol. Clean all tools and sealant gun using a similar solvent immediately after the tooling is finished. TYPICAL APPLICATIONS Bond Breaking Tape Expansion Joint Fillerboard 1st Pour 2nd Pour Lean Concrete HORIZONTAL FLOOR JOINT APPLICATION Backer Rod Expansion Joint Fillerboard 1st Pour Backer Rod 2nd Pour VERTICAL WALL JOINT APPLICATION STORAGE & SHELF LIFE Store in a cool, dry place and keep away from all sources of heat and sunlight. In tropical climates, store in air condition rooms. The shelf life is up to 12 months in unopened condition and if stored as per recommendations. Excessive exposure to sunlight, humidity and UV will result in the deterioration of the quality of the product and reduce its shelf life. Page 4

5 APPLICATION INSTRUCTIONS The surface and joint area to be applied with primer should be dry, clean and free of dirt, dust and any foreign matter. Allow primer to become tacky or touch dry before applying joint sealant. If primer has been applied longer than two hours, reapply another application. Refer to the joint sealant installation instructions for further information or contact CORKJOINT if joint sealant installation training is required. HEALTH AND SAFETY INFORMATION As with all construction chemical products caution should be exercised. Contains manganese dioxide. Which is corrosive and may cause burns to skin if handled without proper protection. Protective clothing such as gloves and goggles should be worn. Treat any splashes to the skin or eyes with fresh water immediately. Should any of the products be accidentally swallowed, do not induce vomiting, but call for medical assistance immediately.
