[Performance Characteristics]

The product is in low viscosity and high penetration. It has strong adhesion and strength after cured.It is abrasion, water, oil, chemical and aging resistant. The glue layer is colorless and transparent and anti yellowing.

[Product advantages]

1.High adhesion and strength, the glue layer is abrasion.

2.Low odor, do no harms to workers;

3.Good age resistance;

4.This product meet the standard of GB18583, ROHS, it is environmental friendly

[Instructions]

1. Slabs treatment

Slabs should be totally dry.

Remove the mud, oil or other purity on the slab surface.

2. Prepare the glue and mix

Mix the glue by A:B=4:1(by weight) completely

Please use up the glue within the pot life. The glue will be fever and is prohibited to use when beyond the pot life. The more of the glue mixed, and the higher of the temperature, the shorter the pot life. If mixed too much glue, please divide quickly to use. 

Do not mix the cap of A and B. Please seal the caps anytime in case the moisture and dash from the air.

The plated with big open mouth container is recommend for glue mixing to extend the pot life of glue

3. Spreading the glue

Spread the glue evenly on the surface of slab with scrape back and forth. The recommend using weight is 80-150g/sqm.

For the cracks on slabs, spread glue back and forth to make the glue penetrate completely.

For big defects on the slab, such as the soil, please remove first, then mix the glue and stone powder to fix it. Polish after cured, then spread glue.

Please do not use the non epoxy and other slab surface treatment agent, or it will be not suitable for the epoxy glue spreading.

4. Glue solidify

The glue will be initially cured in 2-3 house under room temperature(25ºC)It can be proceed to next procedure after 24 hours;

If possible, heat up the stone with adhesive to 50-60 ºC and polish it after 2-3 hours.

Before the adhesive cured, the stone should be placed horizontally and not stacked; after cured, the lubricants such as talcum powder can be applied on the stone surface, to avoid stone adhesion when they are stacked.

5. Clean up

Use the specialized cleaner to clean the apparatus before the glue cured.

[Notes]
1.Some facts will affect the performance of the glue as below:
l The stone is not dry enough or the air humidity is too high, the stone absorbed the moisture from air
l Part A and B was not mixed exactly base on the stipulated ratio
l Glue mix uneven or not completely
l The mixed glue was not used within the pot life.

2.In winter and low temperature, the product may form crystal or caking. Just heat up the glue and make the crystal or caking dissolved, this will not affect the glue performance.

3.Clean and wipe the glue on cloth or skin before it cured with alcohol, then flush with soap water. If in eyes, flush with plenty of water and seek for medical cure; if swallowed, do not emetic, drink plenty of egg white or milk, then seek for medical cure immediately.

[Protective measures]
Due to the individual differences of the operators, the glue may cause allergies to certain parts of the skin, but the product meets the national mandatory standard of GB18583-2008, which is an environmentally friendly product and has no other harm to the human body. It is recommended that your company use the following necessary protection when using the compound glue:
1. Use in a well ventilated environment;
2. Equipped with necessary protective clothing, protective gloves and protective masks;
3. to avoid direct contact with the skin, if you accidentally contact the skin, you can use soapy water to clean;
4. Before adjusting the glue, first open the cover of component B, let the free low molecular substances volatilize, and then take the glue and adjust the glue;
5. If there is an allergic reaction, employees should change jobs.
 

[Stock and Package]

1.Sealed and stock in cool, dry and ventilate place, stock temperature under 5-40ºC. Shelf life one year from the production date, it can be still used based on passing the test when beyond the shelf life.
