Nitoseal PU40 Price in Bangladesh

Description

Description:
Nitoseal PU40-CS sealant is a one component, moisture curing, non-sag, gun-grade polyurethane elastomeric sealant.
It is highly resilient and has excellent recovery characteristics. It can function under wide range of temperatures.

Uses:
Nitoseal PU40-CS sealant is designed for sealing expansion and control joints. Typically used in precast concrete construction, balcony parapets, bridge culverts, retaining walls, boundary walls, roof joints, caulking joints around windows, doors, skirting, walls & floor joints.

Advantages:

• Excellent weathering & ageing properties
• Easy to apply
• Excellent resistance to chemicals & micro organisms
• Can be over painted after curing
• Single component – minimizes wastage
• UV stable
• Strong adhesion to most common building substrates

Standard compliance:
Nitoseal PU40-CS sealant meets or exceeds the test requirements of:

• ASTM C920-14a Types S, Grade NS, Class 25, Use NT,
  Use I, Use M, Use G, Use A and Use O.
• DIN EN ISO11600:2002 Type F 25 LM

Application:
Insert sachet in to Fosroc Barrel Gun. Cut end off sachet and attach cap and nozzle and cut nozzle to desired bead size.
Mask joint sides and insert a suitable backing rod if required. Extrude firmly into joint and tool off using a suitable curved
tool.

Cleaning
Clean equipment immediately after use with Fosroc Solvent 102.

Design Criteria:
Nitoseal PU40-CS can be applied to joints between 2 mm and 35 mm wide and applied between 2 mm and 20 mm deep.

Joints which are expected to experience continual cyclic  movement should be designed such that the sealant is applied to an optimum width to depth ratio of 2:1subject to the overriding recommended minimum sealant depths of: a) 6 mm for accurately formed, non-porous surfaces such as glass and metal, b) 10 mm for precast concrete, in-situ concrete, brick and other porous surfaces.

The sealing slot should be formed using a backer rod (Expancel) which supports the sealant during application and provides a bond breaker at the base of the slot to allow movement to be accommodated over the full width of the sealant.

Instruction for use:
Preparation
Ensure joint sides are square, clean and dry. Remove any laitance, dirt or other contaminants by wire-brushing, grinding
or grit blasting.

Storage
Shelf life
12 months if stored in the original unopened sachets in a cool dry place. Do not store in direct sunlight

Limitations
Not recommended for the following:

• Unprimed joints that will be subjected to continuous water immersion.
• Joints that are contaminated with grease, wax, corrosion, bitumen or cement laitance.
• Horizontal joints in floors or decks where traffic or abuse is encountered.
• Special architectural finishes without proper testing. Application limitations:
• Nitoseal PU40-CS must not be applied to frost-bearing surfaces if temperature will be below freezing for more
  than 24 hours.
• Tooling techniques using solvents or soapy solutions are not recommended.
•  All surfaces must be evaluated for adhesion prior to product acceptance

Precautions
Health and safety
Nitoseal PU40-CS may be harmful if swallowed or inhaled and may cause skin and eye irritation. Product contains a
very small amount of isocyanates and low flash point solvent. Should accidental skin contact occur, remove contaminated
clothing and wash with warm soapy water. Do not scrub.

If inhaled remove person to fresh air. Get medical advice if breathing becomes difficult. In case of contact with eyes,
rinse immediately with plenty of clean water for at least 15 minutes and seek medical advice. If swallowed, give a glass
of water to dilute and seek medical attention immediately – do not induce vomiting.

For further information, refer to the appropriate Product Material Safety Data Sheet.

Fire
Nitoseal PU40-CS does not readily support flame. Prime 7E and Solvent 102 is highly flammable liquid. Keep away from
sources of ignition. No smoking. Containers should be tightly sealed when not in use. In the event of fire, extinguish with CO2 or foam. Do not use water jet.

Disposal
Dispose according to local authority regulations. Do not dispose down drains or into local waterways.
