SIZES AVAILABLE
Silicone Sealant is clear and is available in 75g tubes.
USES
Superior adhesion is achieved on glass, aluminium, stainless steel, most plastics, rubber, wood, canvas, ceramics and glass like surfaces.
LIMITATIONS
▪ Cannot be painted over.
▪ Not recommended for below waterline applications, except for glass aquariums.

TECHNICAL DETAILS
Typical Properties
(Not intended for the setting of specifications) Consistency (as applied):
Non-slump, solvent-free paste.
Curing Mechanism:
Very rapidly develops rubber consistency by reaction with moisture from the air.
Curing Rate:
2mm depth per day.
Skin Forming Time:
5-10 minutes (depending on weather
conditions).
Elongation:
Approx. 400% (ASTM D412).
Service Temperature:
-60oC to +150oC
Joint Movement Capability:
±25% of original joint width when applied in properly designed joint
Properly designed joint refers to the accepted concept of correct sealant
dimensions, ie. sealant depth equal to half sealant width and sealant applied over a suitable backing material to which the
the sealant will not adhere to or does not limit the free movement of the sealant.
HOW TO USE
▪ All surfaces must be clean, dry, and free from soap, dirt, dust, oil, and loose rust. Clean surfaces with mineral turpentine and wipe dry with a clean rag before applying sealant.
▪ Pierce seal on the tube with the reverse end of the cap. ▪ Cut nozzle to the desired opening with a sharp blade; apply nozzle to tube.
▪ For smooth seal, hold at a slight angle and push sealant ahead of the nozzle into joint, ensuring that it touches both surfaces.
▪ For a smooth finish, a tool with a spatula dipped in mild detergent.
▪ Excess sealant must be cleaned up before the sealant skins in 5-10 minutes. Wipe excess away with a cloth dampened in mineral
turpentine.
▪ The sealant will cure fully in 24 hours (based on a thickness of 3 mm). At this point, any unneeded sealant can be removed by trimming with a sharp blade but avoid under-cutting the seal.
For Aquariums
Allow to fully cure for 7 days. Prior to usage, thoroughly wash out with water, drain and refill before introducing fish. Suitable for construction and repairing small aquariums. A specialist design is required for large tanks. Contact Selleys if unsure.
Note: During application a harmless vinegar odor is generated but this disappears as sealant cures.
HANDY HINTS
▪ For a cleaner appearance mask both sides of the joint prior to sealing. Remove tape before silicone skins.
▪ For a better finish complete painting prior to use of sealant as it can not be painted over.
▪ For smooth finish use, a spatula dipped in a detergent solution.
WARNINGS/FIRST AID
Avoid contact with the skin and eyes when uncured. In case of contact with eyes, flush with water for at least 15 minutes and seek medical attention. Wash exposed skin with detergent and water.
Avoid breathing vapor. Use in a well-ventilated area as this product releases Acetic acid while curing.
CLEAN UP
Clean all excess sealant from equipment before it cures with a cloth dampened with mineral turpentine or acetone.
Once the cured sealant is extremely difficult to remove and must be sanded or trimmed with a knife.
