Product Description
DESCRIPTION:
Comensflex 8276 is a low modulus one-component moisture curable polyurethane sealant. It is solvent free, no sagging, waterproof and of good bonding strength, good water, oil, low temperature, aging resistance. It is manufactured strictly under the system of ISO9001 and ISO14001.

USES:
Comensflex 8276 is used as a general purpose sealant for sealing joints in building construction such as movement and construction joints in concrete, such as airfield pavements, brick, wood, concrete jiont sealing, metel and etc.

CHARACTERISTICS:
One component, no sagginess, easy to use
Primerless for most substrates
Excellent durability
Good water and weather resistance
Environmental friendly

APPLICATION:
Joint sealant Design
Correct joint design can assure the lifetime of buildings and sealants. To keep the flexibility of the joints, the minimum width of the joints is 5mm. The depth is 1/2 of the width. The recommended width of the joint is 80-100% of the width if the width is less than 10mm.
In order to assure the designed movement capability of the sealant, we should use back lining. Recommended depth of the joint is no less than 5mm.

Surface Treatment
The surface should be clean and dry. The concrete placement should be dried for 28 days.
After rainfall, it should be aired for 2-3 days. The water content of the substrates should be lower than 9%. Dryness and cleaness can assure the bonding strength to the substrates.
The surface should be clean without dust, oil or loose layers. Metal surface should be of no oil, rusty stains. If the surface is with cladding material or protective layer, we suggest test the sample.

Applying the sealant
Use the brush to clear the surface to make the joint achieve the above requirement.
For good appearance, adhesive tape can be used to paste on two sides of the joint. The edges of the tape should be even with the joint edges.
Pierce the nozzle with an appropriate size at 45° Angle. Put the sealant into an applicator gun and squeeze the trigger uniformly into the joint. The sealant should be filled into the joint and overflow a bit in order to avoid hollow space in the sealant.

Appearance Treatment
Use the scraper and moisten a bit water to press and scrape flat the surface of the sealant. Take off the adhesive tape. Do not touch the surface of the sealant before within its tack-free time.

PACKAGING:
