MS-50 High Quality Medium Modulus Multi-purpose MS Sealant

MS-50 is one component multi-purpose and anti-sagging elastic MS sealant; cured by reacting with moisture in the air, to form a permanent elastomer. It’s silane-modified sealant with the advantages of polyurethane and silicone sealants. it is a flexible sealant widely recognized as with the best overall performance, can meet the needs of adhesive bonding and flexible sealing for a variety of occasions.

Applications

Used in automobiles, buses, elevators, ships, containers, tunnels, rail transit, waterproof dams, nuclear power plants, airport runways, houses, elevated, anti-smashing walls, etc., suitable for high-strength structural bonding and sealing. Suitable substrates include aluminum-plastic panels, marble, wood, concrete, PVC injection molded parts, glass, fiberglass, steel, stainless steel, and aluminum alloys (including painted).

 Advantages

1.Low VOC, no silicone, without bubbles while curing, with very little odor;

2.Good wear-resistance, with a wide range of flexible bonding and durability, primer is not required;

3.It can be painted, polished, bonded and repaired in a repeated manner;

4.UV resistant, anti-aging and weathering resistance, flooding resistant and mould resistant;

5.Neutral Dealcoholize curing, no corrosion and pollution to substrates;

6.Resistant to fresh water, sea water and usually water-based cleaning agents, and has a strong bearing capacity to fuel, mineral oil, vegetable oil and animal fat and crude oil, intolerant to concentrated organic or inorganic acid/base solution or solvent ;

7.For specific requirements, we can provide relevant products and advice.

Operation 

Clean before operation

The bonding surface should be clean, dry and free from grease and dust. If the surface is easily peeled off, it should be removed with a metal brush beforehand. If necessary, the surface can be wiped with an organic solvent such as acetone.

Direction of operation

Tool: Manual or pneumatic plunger caulking gun

For cartridge

1.Cut nozzle to give the required angle and bead size

2.Pierce the membrane at the top of the cartridge and screw on the nozzle

Place the cartridge in an applicator gun and squeeze the trigger with equal strength

For sausage

1.Clip the end of the sausage and place in barrel gun

2.Screw end cap and nozzle on to barrel gun

3.Using the trigger extrude the sealant with equal strength

Attention of operation

- The temperature is lower than 10 °C or the dispensing speed is less than the process requirement, the adhesive is recommended to be baked in an oven at 40 ° C ~ 60 ° C for 1 h ~ 3 h.

- When the bonding parts are heavy, apply the auxiliary tools (tape, positioning block, bandage, etc.) after the sizing installation.

- The best construction environment: temperature 15 ° C ~ 30 ° C, relative humidity 40% ~ 65% RH.

- In order to ensure a good adhesive sealing effect and compatibility of the product with the substrate, the actual substrate should be tested in the corresponding environment in advance.Wear suitable protective clothing, gloves and eye/face Protection. After contact with skin, wash immediately with plenty of water and soap. In case of accident or if you feel unwell, seek medical advice immediately
