Brief instructions :                                   01.01.10
in Resin-Line
Features :
DNS-Denzel Stone Crack Adhesives have an excellent penetration capacity for small cracks.
Even in the finest cracks the adhesion remains excellent after hardening so that stones susceptible to cracking cannot break apart any more while sawing the slabs.
Blemishes on the stone surface are optimally covered !
On light colored and "tender" granites the resin, being rather fluid, can also penetrate into the stone capillars left and right of the crack where it might possibly produce a dark stripe in the crack area !
Test first in inconspicuous area !

Short instruction :
Slabs grinded upto grade 120.
Slabs dry (Denzel ThermoVac oven).
3 resin-application space.
curing time in 60°C oven for 2,5 hours
grinding starting with grade 120 - 2 heads 0,5 and 1 bar pressure

Required Machine-installations :
Large-surface Vacuum lifter.
slab grinder (upto grade 120).
slab-drying-oven (Denzel ThermoVac)
3 resin-application-space.
Large metal spatula.
resin-dosing-machine.
Oven for resin-curing.
appropriate gloves.
Solvent B to clean tools.

Preparation of the stone slabs :
Slabs should be grinded upto grade 120.
Slabs should be dry. (After sawing or grinding, the slabs should be stored for approx. 5 Minutes in the Denzel ThermoVac-dryer).
Big cracks (>0,5 mm) should be sealed from the rear side, using H-970 crack filler.
Already polished slabs, showing very small cracks, may of course subsequently be applied with resin, but it is sometimes necessary to grind the polish again because the polishing sludge has closed these small cracks in such a way that even our crack adhesive cannot optimally penetrate into these cracks.
Before applying the resin, both the resin and the slabs should have almost the same temperature.
Optimal temperatures are between 20 and 30° C.
wet slabs - will produce stains and not adhere properly.
slabs too hot or too cold - will cause a temperature shock of the resin.
If the resin-temperature is lower than 20°C — heat both components with heating-bands around the drums.

Storage of the resin components :
in dry premises at 15° C minimum.
Storage life unmixed approx. 5 years.
moisture would cause rust on the tins.
cold resin has a high viscousity (too "thick" to penetrate into fine crakcs).

Working place :
Keep the working area clean !
Put the barrels on a discharge bench and hang collecting tins under the drain cock.
Spill tree-bark on the working area floor for a better remove of disposed product residue.
resin on the floor can cause an accident and means loss of product.
Working hygiene ! Always use appropriate gloves !
resin on the skin is injurious to health.
BEFORE you start working, apply on hands and arms _Arretil" protective cream made by Stockhausen, Krefeld, Germany.
BEFORE eating or going to the lavatory wash your hands using an acid soap (pH5).

Ingredients :
Component A : reaction product bisphenol A/F and epichlorhydrin resins with a molekular weight of <=700.
Component B : Polyamin
Resin mixture :
Weigh-in the components exactly, in the indicated proportions, using a scale, and mix them with a mixer for approx. half minute. Maximum Mixture Quantity 1 Kg.
imprecise proportions yield loss of product properties.
insufficient mixing causes stains which are irreparable.
if too high mixture quantity - the resin gets fast hardening in the tin.
Apply the resin mixture uniformly on the slab using a metal spatula.
Accumulate the resin mixture over cracks.

Resin coverage :
approx. 25 - 35 g/sqm.
uneven application will result in stains.
insufficient resin cannot stick cracks together.
Use H-954 Solvent B for cleaning the tools.

Curing time before polishing :
Keep the resinated slabs UNMOVED for minimum :
at 45°C approx. 4,5 hours
premature polishing will stick adhesive to the grinding tools.
premature moving of the slabs riscs again breakdanger because resin is not cured.

Disposal of empty drums :
It is possible to use again packing drums which are proper inside. Recycling !
If no recycling - Cut in discharge holes for the tins to be completely emptied.
Do not dispose of the product into the earth and ground water.
Drain off the product and use it - save on product !

Safety :
Liquid resin components are injurious to health if swallowed or in contact with skin.
Therefore take care about working hygiene and use gloves.
In case of contact with the skin, wash with soap and plenty of water.
In case of polluted clothes - take them off immediately and wash the skin.
In case of eye contact - immediately rinse with plenty of water for 15 minutes and consult a physician.
Cortison Depot should be administered in case of any reaction on sensible skin.
The cured resin mixture has no harmful effects.

Our directions for use are only general recommendations to be checked on site for each specific use.
