CHO-83 Gaps & Cracks Polyurethane (PU) Form Sealant

NEUTRAL SILICONE SEALANTS PREVENT MOLD GROWTH

  • ● Ideal for sinks, tubs, showers, vanities, countertops, and more
  • ● Waterproof seal that maintains strong flexibility and adhesion
  • ● Formulated to fight mold and mildew
  • ● All kinds of doors and Windows glass installation, sealing

Overview

CHG A3 one component PU foam is recommended for wooden doors installation. It is suitable for adhesion, fixation, installation, sound insulation, heat insulation, high insulation, sealing moisture proof, dust proof, gas isolation, filling structure gaps, engineering holes and various cracks. (Please operate in strict accordance with our company's installation instruction and call our customer service department for details) 

Products Features

lNormal applicable temperature of the tank:  +5C℃- +35℃.

lOptimum working temperature:  +18℃ - +25℃.

lRange of temperature resistance of cured adhesive:  -30℃- +80℃.

lQuick Curing: Tack free time in 10 min. The foam can be cut, polished or painted after curing for 60 minutes.

lStrong adhesion:  It bonds well to most materials.( Teflon, silicone, etc not included.), Coating on the metal surface is needed if it is applied on metal.

lVibration-resistance:  elastic and buffering.

lAnti - corrosion:  Anti-weak acid, weak base and aging resistance

lHigh efficiency:  Convenient to carry and use, saving time and effort.

lSafety:  no damage to human after curing. 

Package

Packaging Details

300ml/cartridge: 24 cartridges/carton; 1900 cartons/20' container without pallets; 1600 cartons with pallets

590ml/sausage: 1100 cartons/20' container

200L/drum: 75 drums/20'container

Storage considerations:

1) Inversion or side placement is strictly prohibited to avoid valve adhesion and affect normal use.

2)In order to avoid leakage caused by corrosion of the iron tank, It shall be placed in a dry and cool place, and shall not be stored in wet environment

Product Limitation

Be attention the following situations are not require for using:

1. Hide and semi-hide Glass curtain wall structural adhesive.

2. The grease, plasticizer or solvent surfaces.

3. The bad-ventilated places because it is required to absorb moisture in air to cure for the sealant.

4. Frosty or moist surface.

5. Continually soggy or humid place.

6. Surface temperature of materials under 4°C (39.2℉) or above 40°C (104℉).

7. Copper plated mirror, because it will be corrosive slightly on copper plating material.

No.
