Introduction 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.

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.

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.
