SMT neutral silicone weather resistant sealant,Silicone sealant

Silicone sealant is polydimethylsiloxane as the main raw material, supplemented by cross-linking agent, filler, plasticizer, coupling agent, catalyst in the vacuum state mixed paste, in the room temperature through the water in the air should be cured to form elastic silicone rubber.

(1) Purpose

I. Acid glass glue

1. Suitable for sealing, plugging and anti-leakage and anti-wind, both indoor and outdoor are suitable, with significant anti-seepage and anti-leakage effect.

2. Adhesion of various automotive interiors, including metal, fabric, organic fabric and plastic.

3. Connect the gaskets on the heating and cooling equipment.

4. Steel bars without screw holes, nameplates and lacquered plastic materials shall be installed on the metal surface.

5. Seal the window on the oven door, the flue, pipe joint and the access door on the gas appliance.

6, for the gear box, compressor, pump to provide immediate formation of anti-leakage pad.

7. Seal the cabin and Windows.

8, trailer, truck cab window sealing.

9. Bonding and sealing equipment components.

10. Form anti-wear coating.

11. Inlay and fill thin metal lamination, duct network and equipment housing.

Neutral weather-resistant adhesive is suitable for weather-resistant sealing of various curtain walls

1. It is especially recommended for weather-resistant sealing of glass curtain wall, aluminum-plastic panel curtain wall and stone dry hanging;

2. Joint sealing between metal, glass, aluminum, ceramic tile, plexiglass and coated glass;

3. Joint sealing of concrete, cement, brick, rock, marble, steel, wood, anodized aluminum and painted aluminum surfaces.

Primer is not required in most cases.

Silicone structure glue is mainly used in the glass curtain wall between metal and glass structure or non-structural adhesion assembly.It can connect the glass directly with the surface of the metal component to form a single assembly assembly, which can meet the design requirements of the curtain wall with full or half hidden frame.

(2) Conditional restrictions

I. The use of all kinds of silicone glass adhesives is subject to the following restrictions:

1. It is not suitable for construction where water has been flooding for a long time;

2, do not participate in the exudation of oil, plasticizer or solvent materials phase solution;

3, frost or wet surface can not be bonded;

4. The completely closed place cannot be cured;

5, the substrate surface is not clean or strong.

Ii. Acidic glass glue has the following restrictions:

Acidic silicone glass glue will corrosion or not bonded copper, brass (and other copper alloys, magnesium, zinc, electroplating metal (and other zinc alloy), at the same time Suggestions on iron carbide and matrix of the brick stone made don't use acidity glass glue, the methyl methacrylic acid salt, poly carbonate, polypropylene, polyethylene and use this product made from ptfe material will not be able to get a good bonding effect and good intermiscibility.In addition, acid glass glue should not be used where there are abrasions and substantial drawbacks.The base material surface temperature of silicone acid rubber exceeds 40℃ and is not suitable for construction.
