JOINLEADER NP Neutral Silicone Sealant

PRODUCT DESCRIPTION

JOINLEADER NP Neutral Silicone Sealant is a middle/high modulus, high quality, cost effective, low odor, multi-purpose, one-part neutral curing sealant.

JOINLEADER NP Neutral Silicone Sealant offers excellent adhesion and long term durability, compatibility with a wide variety of substrates, and good weatherproof ability.

Used in a range of general sealing, general glazing, waterproofing and trade applications.

FEATURES

Stable and flexible from –50°C to +180°C

Adheres to a range of common building materials and finishes.

Neutral cure, will not corrode metals, concrete or brick.

Cures to a strong, flexible seal capable of withstanding movement in and around the joint.

Non-slumping, can be used in vertical and overhead joints.

Easy to use – one part, no mixing required.

Resistant to weathering, ultra-violet radiation, vibration, moisture, ozone, temperature extremes, airborne pollutants, cleaning detergents and many solvents.

APPLICATIONS

JOINLEADER NP Neutral Silicone Sealant is a low/middle modulus silicone adhesive/sealant designed for applications where non corrosive curing and durable adhesion to a variety of substrates is required.      

JOINLEADER NP Silicone Sealant is ideally suited for general purpose glazing, sealing and weatherproofing applications, has excellent adhesion to glass, glazed surfaces, anodized aluminum, concrete, cement, wood and many plastics.

It is widely used in industry building, automotive, package, and family decoration for joints adhesion and sealing among glass, ceramics, aluminum alloys, plastics, woods, paper etc.

APPLICATION LIMITS

JOINLEADER NP Neutral Silicone Sealant is not suitable for adapting to structural fitting and following situations:

1. To all surfaces that bleed oil, plasticizers or solvents such as wood immersed in oil, oil crack filler, and some uncured or sulfurized fat and to surface where is wet;

2. To the substrate that the surface temperature exceeds +50°C or apply at temperatures below 5°C;

3. Use in the manufacturer of IG units;

4. To closed or confined areas where sealant cure may be inhabited by lack of air (silicone sealant need the water in the air to cure);

5. To use in construction or sealing of aquariums;

6. To the painted surfaces, may cause seal failure as the paint cracking or stripping;

7. To the surfaces that with direct touch of food.

8. Do not use for structural glazing.

9. Not recommended for continuous water immersion applications.

10. Not recommended for use with marble and similar highly porous

11. Not recommended for joints where movement exceeds ±20%.

12. Not recommended for use in below ground joints or trafficable

13. Joints where abrasion and physical abuse are encountered.

14. Contact with acetoxy silicone sealant

HOW TO USE

APPLICATION TEMPERATURE:   +5°C to +40°C

Cleanse with a cleaning agent, to keep the substrate surfaces completely clean(JOIN LEADER also provide the cleaning agent for your convenience).

Use the sealant after cleaning agent dries, around 1~2mins later. You can use two different cloth, one for cleaning agent, and the other for sealant. (Notice that the two can’t be mixed use together, and the second cloth will be better purified cotton and no picking.)

For better appearance, cover outside of joint areas with masking taps before application.

Cut nozzle to desired size and extrude sealant to joint areas.

Tool immediately after sealant application, make it smooth and remove masking tape before sealant skins.

SHELF LIFE

12 months in unopened packaging in a cool and dry storage place at temperatures between +5°C and 27°C.

COLOR

Transparent, gray, black and white.

Also we can produce the sealant with special color upon customers' requirement.
