Uniblock 110 H Superior Hybrid Adhesive Semisolid

CHEMICAL NATURE

Bi-component adhesive of superior class based on hybrid resins (mix polyester and vinylester).

ASPECT

Thixotropic paste of neutral colour (transparent-opaque).

FIELD OF APPLICATION

Bonding of synthetic agglomerates and artificial stones, marble, granite and ceramics where it’s important the final aesthetic look of the joint and when an adhesive of high quality is needed. For its consistence and aspect product is suggested for crystalline products and marbles and granites “multicolor”

PROPERTIES

Good adhesion to any kind of natural and artificial stone (provided with sufficient porosity).

HARDENING

By adding a 3% of catalyst in paste, the product hardens in 10 minutes about (at 23°C/73.4°F) The low exothermal peak, developed during the hardening phase, allows modest shrinkage, among the lowest of its category. The glue, once hardened, stands to temperature also higher than 80°C (176°F) without softening.

HOW TO USE

• The material to be treated must be clean, dry, free from dust or greasy substances and friable parts. • Polished surfaces must be previously sanded. • Use at it is or mix with the proper colouring pastes (max 3%) or with the powder of the same stone. • Mix carefully with a max. 3% in weight of hardener/catalyst. The texture remains workable for a short time that can vary according to the quantity of hardener, the temperature, the thickness, etc. • Apply to one or both the surfaces of the joint and unite them with a light pressure • Polished surfaces must be previously sanded. • The hardened product just maintains a semi-transparent appearance with white shades, little or not visible in the thin layer • 3 hours about after hardening (at 23°C/73.4°F), the material can be worked (drilled, grinded, polished, etc.) • Use solvent for cleaning the work tools. Note The persistence of a slight stickiness subsequent gluing, allows for a significant increase in adhesion • The maximum adhesive effect occurs after 24 hours Note After about a week, the colour of the hardened putty acquires a shade that tends to light yellow low or not visible in thin layer.

SUGGESTIONS

ƒ During the work and during the hardening process, it is developed styrene; protect the hands by impermeable gloves and air the room in order to reduce the vapours inhalation. More information about safety by consulting the Material Safety Data Sheet.

ƒ High temperatures (>30°C / >86°F) or quantity of hardener higher than 2% accelerate the reaction and reduce the adhesion and can cause a strong darkening of the adhesive.

ƒ Low temperatures (<5°C / <41°F) or quantity of hardener less than 1% slow down the reaction and can cause superficial unctuousness.

ƒ Freezing and thawing, strong and frequent thermal or humidity changes reduce the chemical resistances.

ƒ The hardened adhesive can be removed only mechanically.
