Description
SV-GT2000 High-speed rail subway silicone sealant is a one-component, low modulus, neutral curing adhesive. For most of the stone, ceramic and cement components, can produce excellent adhesion
Key Features
(1) easy to use: can be used at any time out;
(2) excellent thixotropy and extrusion, at any temperature (-40 ℃ to 100 ℃) can be extruded;
(3) good adhesion, the stone, ceramics and cement components and other building materials with excellent adhesion properties; no pollution of the porous material;
(4) excellent weather resistance, aging performance, excellent tensile and compression resilience, can carry ± 30% displacement capacity;
(5) neutral curing, stone, cement and other building materials without corrosive, to overcome the shortcomings of acid corrosion material.
(6) base modulus: passive deformation occurs when the role of moderate stress on the concrete substrate to ensure that the concrete surface is not destroyed;
(7) high elasticity high recovery capacity: can be repeated from the seams with the movement, fast response fast response, permanent deformation of small.
Basic Application
1.For high-speed rail track, airport runway, highway irrigation joints sealed, can withstand large displacement;
2.Can also be used for other concrete pavement sealing, subway engineering, tunnels, bridges and other projects sealed.

How to PROPERLY use die-electric grease on spark plug wires.
What is Dielectric Grease?
Dielectric grease is widely used as a sealant for spark plugs in gasoline or diesel engines, as well as on the gaskets of multi-pin connectors in the electrical systems of vehicles and boats. When used with spark plugs, it’s applied to the rubber part of the plug wire. This helps the boot slide onto the plug’s ceramic insulator and keeps dirt or moisture from contaminating the seal and disrupting the electrical current.
Besides being used to seal rubber covers on electrical connections, dielectric grease also prevents corrosion when applied directly to metal connectors. Though it works well for this purpose, it can sometimes cause a connection to stop working if not all of the grease is pushed out of the way between the points of contact inside the connector. Additionally, it is often used to lubricate other engine-related parts, like rotors, distributor caps, and speedometer cables. It can be used in other situations where electrical connections may be exposed to moisture and dirt as well, like outdoor lights, satellite TV installations, trailer hitch wiring, and battery terminals.
———————————————————————————
You do NOT have to apply dielectric grease to the boots on distributor end.
Why you ask? Multiple reasons.
#1 – You don’t have to worry about arching-to-ground since the cap is one big insulator; far enough from a ground source.
#2 – There isn’t much heat at the distributor end to worry about the boot seizing to the distributor cap.
#3 – The main reason. You don’t want the boots/terminals from the spark plug wires to pop-off the distributor cap. It’s true and does happen. How? When you push-on the spark plug wire’s boot onto the distributor cap, you have to burp-out the air from under the boot. If not, the air pressure under the boot can cause the boot (and terminal) to rise up separate from the cap’s terminals. You might not even know this has happened.
Since the “towers” on the cap are tapered, by their very design, the boots want to ride-up the towers. If this happens, arching will occur. Or, worst case scenario, the wire will completely pop-off. A non-greased boot will cause the boot to better stick to the cap. So in this case you want the boot to stick (not seize) to the cap.
NOW, if you were to add dielectric grease under the boots, and push the boots onto the distributor cap, there will such a tight seal that the air under the boot can’t burp-out. In addition, the grease will make the boots more slippery and make it even easier to pop-off the cap.
Although it might not make sense now, give it a try the next time you change your plug wires or cap. Then you’ll see what I mean.
