Introduction of ms sealant

Introduction of ms sealant

Ms sealant is an adhesive used to fill the gap in the configuration to play a sealing role. It mainly introduces a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is divided into elastic sealants, liquid gaskets and gaskets. There are three major categories of sealed putty.
Sealant has the functions of preventing leakage, waterproofing, anti-vibration, sound insulation and heat insulation, etc. It is widely used in the sealing of construction, transportation, electronic instruments and parts.
Sealants are usually based on dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber, and inert fillers such as talc, clay, carbon black, titanium dioxide, and asbestos. Then add plasticizers, solvents, curing agents, accelerators, etc. to make.

Sealing characteristics of ms sealant

①Good embedded filling, squeezing construction, storage stability, non-toxic or low-toxic; liquid, gas;
② Low penetration with other media;
③ Joints that can resist telescopic movement, displacement and deformation; joints deformed in cycles;
④It can ensure the complete recovery of its performance and shape;
⑤Have enough strength to withstand pressure;
⑥ No peeling, the stability of the joint base degumming adhesive;
⑦Don't soften excessively at high temperature and low temperature without brittleness;
⑧ Weather resistance, no chalking, cracking, dissolution or excessive shrinkage, enough life;
⑨Specific occasions, such as wear resistance, puncture resistance, corrosion resistance, rolling resistance, flammability, non-polluting, insulation or electrical conductivity.

Ms sealant construction method

1. Clean the part to be repaired and remove oil and dust;
2. Set the width of the gap filling and paste the masking tape to ensure that it is smooth and beautiful after construction
3. Smoothly squeeze the glue gun with a 45-degree angle of construction to glue and seal the gap;
4. Use a steel ball rod to smooth the surface of the modified colloid along the surface of the glued area to remove the excess colloid;
5. Carefully tear off the textured paper, and the colloid should not be touched 3 hours before the initial curing;
6. The colloid will cure completely the next day.

Identification method of sealant

There are many types of sealants: silicone sealants, polyurethane sealants, polysulfide sealants, acrylic sealants, anaerobic sealants, epoxy sealants, butyl sealants, neoprene sealants, PVC sealants, and more Asphalt sealant.
The selection of sealant mainly depends on several properties: 1. Breaking strength (stretching force/cross-sectional area); 2. Bonding strength (stretching force/bonding area, except for substrate damage); 3. Breaking elongation Length rate (length when broken/original length); 4. Anti-aging ability; 5. Appearance (sub-luminosity, particles, bubbles); 6. Shape retention (no wire drawing, no façade sagging); 7. Shelf life; 8. Curing time.
There is no good or bad glass glue, performance corresponds to the price, suitable for the best. Secondly, there are stability and sufficient quantity, which are tests for manufacturers. If the capacity of the sealant is less than the marked capacity (note: it is the capacity. The situation of the sealant is very serious), such a sealant should be eliminated first. There is a problem with the business thinking of this kind of business, and the product is not much better. (There are also many problems, which proves that the production process of its products is not strictly controlled). If the amount is large, the production stability of the sealant must be considered.

User Reviews

What users say about JOINTAS

The sealant has a fine texture and no bubbles, and the taste is very small. It is very convenient to use and dries very fast. The instructions are very detailed. The effect is good after using it.


The packaging of this product is very good, very strict, and the design is very scientific.


The product I bought is really good. The other ones I bought before have a lot of particles in it. They are not smooth to the touch. I don’t know how to use it, and the beauty stitches I bought make it. I really don’t have to say.


The effect is very good! The smell is very small, almost no smell during construction.


The quality is very good. I made it at home by myself. It's okay. The effect is good. The quality is indeed better than the price bought in other stores.


The smell is very small, the gel is translucent, it is smooth to use, and it dries quickly. The anti-mildew effect needs time to test.

Frequently Asked Question

Easy to use, with a certain pertinence. Sealant refers to a sealing material that deforms with the shape of the sealing surface, does not flow easily, and has a certain degree of adhesion. It is an adhesive used to fill the gaps in the configuration to play a sealing role. It has the functions of anti-leakage, waterproof, anti-vibration, sound insulation and heat insulation. Usually dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber are used as the base material, combined with inert fillers such as talc, clay, carbon black, titanium dioxide and asbestos, and then added Made of plasticizer, solvent, curing agent, accelerator, etc. It can be divided into three categories: elastic sealant, liquid gasket and sealing putty. It is widely used for sealing of construction, transportation, electronic instruments and parts.

According to the material, it is divided into polyurethane sealant, silicone sealant and other products. The main raw materials used by each are different, and the scope of application is different. According to the curing method, it is divided into low temperature curing, normal temperature curing and heating curing. Different curing methods have different requirements for working environment temperature.

The sealant has good sealing performance and can effectively prevent leakage such as oil leakage. It is also convenient to use for waterproof, anti-vibration, sound insulation, and heat insulation. It is not as troublesome as using rubber asbestos boards, and the sealing effect is really good.
