Key Advantages of GP Black Silicone Sealant

Rapid Crosslinking

One of the key characteristics of this black silicone sealant is rapid crosslinking. The applied material quickly becomes tack-free under suitable curing conditions.

This helps reduce the period during which the fresh sealant remains exposed to dust and surrounding contamination.

Excellent Adhesion

GP General Purpose Silicone provides excellent adhesion to a selection of commonly encountered materials, including glass, vitrified surfaces, ceramic tiles, selected plastics, and most suitable coatings.

Correct substrate preparation remains essential for achieving dependable results.

Non-Sag Consistency

The product is formulated with non-sag properties, helping the applied bead remain in position during suitable applications.

This makes the sealant practical for vertical and other joints where excessive material movement after application would be undesirable.

Easy Application Across Different Temperatures

The sealant offers ready gunnability at application temperatures ranging from approximately +5°C to +40°C.

This broad processing range makes the cartridge practical for many interior and exterior installation conditions.

Flexible at Low and High Temperatures

Once properly cured, the material maintains flexibility across temperatures from approximately -40°C to +100°C.

This temperature flexibility helps the seal accommodate appropriate environmental and service conditions without behaving like a rigid sealing material.

GP General Purpose Silicone provides the flexibility associated with silicone technology while offering good adhesion to many common suitable substrates.

As a construction sealant, it can therefore be useful for appropriate sealing work involving glass, tiles, coated surfaces, and other compatible materials.

Its non-sag consistency is another practical benefit for construction and installation work where a controlled bead is required.

For contractors and installation teams, New Tech provides GP Black Silicone as part of its professional construction and maintenance product range.

Surface Preparation Before Applying the Sealant

Proper preparation is one of the most important steps in achieving good sealing performance.

The substrate areas that will come into contact with the Silicone Sealant should be:

• Clean.
• Dry.
• Free from dust.
• Free from dirt.
• Free from loose rust.
• Free from oil.
• Free from other contaminants.
• Free from loose material that could interfere with adhesion.

Applying sealant over contamination can reduce the quality of the bond between the silicone and substrate.

Preparing Non-Porous Surfaces

For suitable non-porous substrates, the surface can be cleaned with an appropriate solvent and a clean, lint-free cotton cloth according to the product instructions.

Any remaining solvent should be removed with a fresh, clean, dry cloth before it evaporates.

Careful cleaning helps create a properly prepared surface for the general purpose silicone sealant.

How to Apply GP General Purpose Silicone Sealant

The 280ML cartridge format is designed for straightforward application with an appropriate sealant gun.

Step 1: Prepare the Joint

Clean and dry the surfaces thoroughly, removing all loose materials and contaminants.

Step 2: Open the Cartridge

Cut open the cartridge thread as instructed.

Step 3: Attach the Nozzle

Secure the nozzle onto the cartridge.

Step 4: Adjust the Bead Size

Cut the nozzle according to the required bead dimensions for the application.

Step 5: Apply the Silicone

Use a suitable cartridge gun to apply the black silicone sealant in the required bead or layer.

Step 6: Allow Moisture Curing

The sealant requires moisture to cure, so sufficient curing conditions must be provided before the sealed assembly is placed into full service.

How Does GP Silicone Sealant Cure?

The product requires moisture from the surrounding environment to complete the curing process.

Several environmental conditions can influence curing speed.

Curing can take longer when:

• Temperatures are lower.
• Relative humidity is lower.
• Air exchange is limited.

Therefore, curing time should not be treated as identical under all working conditions.

Temperature, humidity, airflow, bead dimensions, and application conditions can all affect the curing process.
