automobile sealant /PU sealant/PU: 1.metal plates and the framework of automobile 2.adhesion of glass curtain wall

automobile sealant /PU/PU sealant:

Description:H-168 pu automobile sealant is mainly applied for the adhesion of the metal plates and the framework of automobile, and the sealing of the welding joint of the refrigeration compartment; The joint filling of the side window glass of the passenger coach; the adhesion and sealing of the glass curtain wall etc.

Application:1. The metal plates and the framework of automobile2. The welding joint of the refrigeration compartment3. The glass curtain wall4. The side window glass of the passenger coach

Characteristics:1. Single components facilitationg  application to prevent the compulsory application once and all after mixed on construction sites ,thus causing no waste 2. Elastic, Good Initial Adhesion, and Moderate Intensity3. Good Gap-filling Capacity4. Short Drawing Wire When the Gluing Stops5. No Corrosion on Base Material, No Penetration Pollution6. Room temperature and humilidity curing:without any necessary heating , there is a wide range of construction temperature ,so construction can be carried out at a temperature betweeen 5oC and 40oC.7. Good weathering resistence Good Ageing Resistance.

Instruction:The sealed place must be completely cleaned and dried. If necessary, washing them with solvents such as toluene or acetone. In order to keep better appear range. The joint of cover outside areas should be masked with tape before sealants apply. Sealant can be repaired immediately and the masking tape should be removed before the sealant skins. Previous using experiment is necessary beforehand.

Limitions:

1. Don't use in structure glazing. 2. Don't use in aquarium assembly and sealing. 3. Don't use in places where have permeated grease, plasticizer or solvent such as wood permeated oil, uncured or half-cured resins. Etc. 4. Don't use to joints which is hidden in earth or immersed in water for long time. 5. Don't use to complete sealing space, results to lack of hydrosphere can't good solidify
