In industrial production, waterproof sealant is an indispensable material. Especially in the seawater or electrolyte environment, electronic equipment subjected to seawater corrosion for a long time, the choice of appropriate waterproof sealant is more important. So what glue is resistant to seawater or electrolyte immersion? This article will introduce in detail for you, and analyze its advantages and disadvantages to help you make a choice.
 
1. Fluorosilicone MS sealant
 
merit:
 Good high and low temperature resistance: fluorosilicone MS sealant can still maintain elasticity and adhesion at extreme temperature.
 UV resistance: suitable for outdoor environment, long-term exposure to sunlight will not degrade.
Chemical corrosion resistance: it has a very good corrosion resistance to seawater and some electrolytes.
 
shortcoming:
The adhesion force on the surfaces of some special materials is inferior to other types of sealant.

2. Polyurethane-modified sealant
 
merit:
 Strong adhesion: excellent adhesion to most material surfaces.
 Good wear resistance: with good wear resistance, suitable for the need for frequent friction parts.
Good toughness: solidified with good toughness, can adapt to small changes in the structure.
 
shortcoming:
 Uv resistance is generally good: long-term exposure to sunlight will age.
 General elasticity: no obvious elasticity, and large stress.
High temperature resistance has limitations: long-term use temperature does not exceed 135 degrees Celsius.
 
3. Epoxy resin-modified MS sealant
 
merit:
 High strength: after curing high strength and elasticity of silica gel, with excellent mechanical properties.
Chemical corrosion resistance: have good corrosion resistance to chemical reagents such as acid and alkali.
 
shortcoming:
The viscosity is not adjustable.
 
Four, polysulfur sealant
 
merit:
 Excellent chemical resistance: good corrosion resistance to a variety of chemicals, suitable for harsh chemical environments.
 Good elasticity: after curing with a very good elasticity, to adapt to the change of the structure.
Good weather resistance: stable performance in various climate conditions, suitable for outdoor use.
 
shortcoming:
 High price: the cost of polysulfur sealant is higher, not suitable for large area use.
 Complex construction: professional tools and technology are needed, and the construction is more difficult.

The performance of these sealants is very dependent on the formula, the different raw materials, the performance differences are obvious. And the glue verification cycle is long, especially facing aging, yellowing, decomposition and other problems, affecting the life of the product, we should pay special attention to when choosing.
 
sum up
 By introducing the five kinds of ENIENT MS glue and its applicability in the five application scenarios, this article will help you to understand and choose waterproof sealant, and provide valuable reference for your engineering and daily applications.
