Hot mirror hollow glass is composed of two layers of glass and a special hot mirror film, and is separated into a double cavity hollow structure by double-layer special spacers.
Features:
Heat insulation and high efficiency shielding of ultraviolet rays
High light transmittance to prevent condensation
Efficient sound insulation, energy saving and environmental protection
Composition
single component, neutral, room temperature moisture curable silicon modified polyether sealant.
Application Application
building interior door frames, window sills, and other interior parts of the sealing seal;
variety of building materials and interior parts of the binder, such as bonded aluminum, concrete and the like, kitchen mirrors, pendant adhesive;
Other suitable bonding and sealing applications for this product art construction.
Application Method
Before using this product, the operator must carefully read the product safety data sheets.
Surface must be clean, dry and free of dirt, water stains, frost, surface dirt, residual sealant.
In both construction surface protective tape affixed using a suitable sealing material in the gasket.
Beak incision size as needed, and should be filled continuously extruded into the interface, the amount of sizing adhesive should meet in full contact with the sealing surface.
When the sealant has not been surface crust, a suitable sealant strength flattened onto the backing material and the joint surface, and removing the protective tape.
Construction and curing process should maintain good ventilation.
To ensure optimal bonding effect, before the start of the project should be carried out adhesion tests must be compatible with the primer used when necessary. Peel adhesion testing should be carried out regularly in the construction process to ensure construction quality.
Storage and Validity
Well-packaged product in a cool, ventilated, dry place can be stored for 12 months in product packaging "valid" before use
Packaging
Plastic tubes: Each 300ml, flexible packaging carton 25: Each 600ml, carton 20
Limitations Use Restriction
The use of glass inserts should be used;
Not for non-ventilated place, because the sealant needs to absorb water from the air in the air cured;
Not for the places under water or humid surface;
Not for leaking grease, plasticizer or solvent materials, such as oil-soaked wood surface;
Should not be used polypropylene, polyethylene, polytetrafluoroethylene bonding;
The material surface temperature is below 5 ºC or above 40 ºC, not construction;
When using light colored sealant, should avoid contact with acidic or alkaline substances (e.g., wall cleaning liquid), in order to avoid discoloration.
Bonding cement, concrete substrate when the substrate must be completely dry before construction and conservation of 7 days, otherwise it will affect bonding properties.
