High Performance Yf 851 Single Component Polyurethane Adhesive To Brazil - China

High Performance One Component Polyurethane Adhesive to Brazil

I

Q: Please introduce the polyurethane adhesive.

A:

polyurethane adhesive is elastic sealing materials which are one component, moisture curing polyurethane foam filling, multi-purpose .

Filling Polyurethane pre polymer and catalyzer and gas propellant in iron aerosol cans withstanding pressure.

When constructing, Spray aerosol gel to the site of the construction by using matching sizing gun or manual nozzle.

And complete molding, foaming, bonding and sealing processes in the short term.

Cured foam elastomer of Polyurethane (PU) foam sealant has a lot of excellent performance, such as bond, waterproof, withstanding thermal expansion and contraction, heat insulation, sound insulation and even flame retardant, etc.

II

Q: What matters should be attention to about polyurethane adhesive?

A: The following matters should be attention to:

1 - No burning or piercing material tank and empty tank after using.

2 - Do not invert during transporting and storage processes.

3 - The construction site should have good ventilation conditions.

Construction personnel should wear work gloves and goggles work clothes.

At the same time do not smoke.

4 - The non - solidified foam is sticky to the clothes and the skin.

Pay attention to protection when using.

If the bubble is touching the eyes, rinse immediately with water and consult a doctor.



III

Q: What are the key points of construction operation about polyurethane adhesive?

A:

1 - process flow

Clean - details of basic level surface to make glue, besmear to brush glue (cold) base oil - details attached middle construction - the first time and the second time coating and coating to third time coating waterproof layer construction, waterproof layer a test to cover ACTS the role of surface, waterproof layer second acceptance test and waterproof layer.

2 - Before construction of waterproof layer, should swept away the primary surface dust and other debris, and use wet cloth clean to brush one more time.

3 - Besmear brushs the waterproof layer of the basic surface, can not have uneven, loose, empty drum, play sand, cracking and other defects, the moisture content is generally not more than 9%.

4 - Besmear bottom glue (cold priming oil) :

1) Dispensing glue, first to add a and b material polyurethane xylene, ratio is 1: 1 - 5: 2 (weight ratio) and mixed amount shall be determined according to specific situation, unfavorable and overmuch.

2) Brush glue, according to the law on preparation, good glue mixture evenly with the roller surface at the grassroots level, besmear brushs the amount of 0.15-0.2 kg/m2, besmear after normal temperature season 4 h later, feel is not sticky, can do the next working procedure.

5 - Coating waterproof layer construction: Polyurethane waterproof material for Polyurethane material a, Polyurethane material b and xylene, ratio of 1: 1, 5: 0 - 2 (weight ratio).

V

Q: What is the storage mode about polyurethane adhesive?

A: The period of validity is 12 months.

It should be placed in a cool and dry place.

Avoid direct sunlight and the temperature should not exceed 50 degrees.


VI

Q: What's about the application of polyurethane adhesive?

A:

Door and window installation: Caulking, seal, fixed bonding between doors and windows and wall.

Waterproof plugging: Repair of plugging of Tap water pipes, sewers and other loopholes.

Thermal insulation filling: Insulation joint of cold storage and air conditioning.

Daily maintenance: Repair the empty of slot, wall tiles, tiles and floor.

Sound insulation and noise elimination: Gap filling of the meeting room or Sound lab during renovating.

Packaging and transportation: It is convenient to packaging fragile valuables.
