Application:
It could be applied to the quarry and factories for filling and curing the blocks that are not suitable for sawing or transportation, and to repair the stones' surface and internal defects.

Features:
The product is two-component modified epoxy resin adhesive, which has the characteristics of low viscosity, strong permeability, slow curing speed, low shrinkage, strong adhesion after curing, good medium resistance and excellent aging resistance. It could be perfused and wrapped by one time with the professional perfustion equipment, where can avoid the blocks be wasted and destroyed.

Advantages:
1. low viscosity, strong permeability, can permeate tiny micro cracks, with strong repairing ability;
2. Non-volatile, slight odor, low irritation, and convenient operatings and processing;
3. High bonding strength, strong adhesion, excellent aging resistance, good toughness of the resin layer and good yellowing resistance;
4. The product conforms to GB18583, GB30982 standard, EU ROHS, eco-friendly.

Usage Manual:
1. requirements of block
A. The blocks to be poured shall be free of impurities such as dust, dirt, sand and oil;
B. If there are large defects on the surface of the blockage, if there is soil layer or sandstone, it should be removed first. The oil can be scraped off or ground with a solvent such as alcohol or acetone, then rinsed with a high-pressure water gun, placed under the sun or dried. The place where the surface of the block is dry is basically anhydrous and ready for use.

2. Mixing adhesive
a. Mix adhesive at rate of A:B= 3:1 (by weight) evenly.
b. Mixing rate must be correct, must mix evenly, avoid mix the glue taking tools and put the mixed adhesive back to packing barrels.
c. Mix the glues when use, and the glue must be use up within operation time. Must stop use the glue which be heating up when the time is exceed the stipulate operation time. Between 25-30℃, mixed 600g glue should use up within 5 minutes ; more glue mixing , higher temperature, and shorter operation time , in contrast the operation time is longer . Should separate glue rapidly when excessive .
d. Don’t mix the caps of the package of A and B components, even operating need keep close caps immediately to avoid dust and moisture from atmosphere .

3. Perfusion
A.The ideal temperature for perfusion is 15-35℃;
B.The mixed glue is poured into the block with a dedicated block filling device.

4.Curing
A.Initial curing at room temperature （25℃）for 10-12 hours, after 48 hours, it can be put into the next process;
B.The construction temperature should not be lower than 5℃. When the ambient temperature is lower than 10℃, the curing speed of the glue will be significantly slowed down. It is recommended to use heating to promote the curing.

5.Cleaning
Use special cleanser to clean the operation tools before solidifying entirely.
