Medium Modulus Multi-purpose MS Sealant MS 50
 
Product Description
 
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.
 
 
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

∎Directions for Use

● Cleaning:The substrate surface must be solid, dry and be clean.Such as no dust, grease, asphalt, tar, paint, wax, rust, water repellent, curing agent, isolating agent and film. Surface cleaning can be dealt with by removing, cutting, grinding, cleaning, blowing, and so on.

● Operation:Put the sealant into the operating tool,then injecting it into the gap.

● Reservation gap:The construction joint will expand as the temperature change,so the surface of the sealant should be lower than 2mm of the pavement after construction.

● About maintenance time: At the standard state, the maintenance time is about 5 hours. It depends on the actual construction conditions. The standard state is that the temperature is 23±2℃,and the humidity is 55 ± 5%RH.

● Operation Methods: Because the packing is different, the construction methods and tools are slightly different. The specific construction method.
●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.
