Two-component stone glue Chemfix

Stone glue is one of the widely used industrial materials, which is considered an inseparable principle and a very practical item in construction activities. Stone glue (ChemStone) based on epoxy resins in the form of a two-component paste with very high binding and adhesion power, suitable for dry facades, bolt planting and gluing different types of building stones such as porcelain, granite, travertine and artificial stone on the base. different are used. This two-component paste adhesive in part (A) of epoxy resin usually consists of monomers and short chain polymers consisting of epoxide group, plasticizers, rheology modifiers, thixotropic agents and inorganic and organic additives. Part (B) consists of amine hardener, polyamides and inorganic and organic additives. The production of these products complies with ASTM C 882/C, ASTM C39 standards.

Storage conditions: away from heat, humidity and sunlight.
Storage temperature: 10 to 40 degrees Celsius is the most suitable temperature for storage.

Method and preparation of two-component stone glue

Surface preparation

Resin and hardener should be kept at room temperature of 25 degrees Celsius for 24 hours before installation. All surfaces must be free of grease, dust, hardening agents and other contaminants. It is also necessary to clean and dry the surface before applying epoxy glue. The surface of any product that is to be bonded using adhesive must be prepared and reach the surface of the hard, pure stone substrate behind it to be covered and bonded by the adhesive.

The surface must first be sanded and made uniform with an abrasive roller or diamond blade, and the resulting dust should be removed with a hair brush and the entire surface cleaned. After that, you can use a wet sponge to clean the remaining dust from the surface and ensure complete connection.

Method of Use

First, the first and second components should be well mixed together in the same weight ratio. To do this, take the necessary amount of each component of the product with a separate spatula and mix them completely and evenly with another separate spatula. Note that after mixing, the optimal working time is 15 to 20 minutes. In other words, the user must complete the biting and installation and rigging of the stone within a maximum of 20 minutes.
We remove a sufficient amount of mixed glue with a spatula and place it on the surface in the form of conical bites at appropriate and equal distances from each other.
After biting, the stone is removed and placed on the predetermined infrastructure and re-ligated. The initial setting time or gel time of this product after mixing is between 30-45 minutes depending on the ambient temperature and it becomes completely hard after 12 hours. If the stone to be connected has little weight or its dimensions are small, the pasty state of the glue will have the ability to maintain it until it reaches the appropriate hardness. But if the weight of the stone is too much, it should be protected using physical tools. In the continuation of the operation of gluing the stones, the next rows should be continued continuously without wasting time.

Consumption

The amount of stone glue used for an area between 3 and 5 square meters in the case of vertical stone work is equal to 4 kilos, which depends on the weight and dimensions of the stone and the flatness of the surface under the work. This amount is reduced for horizontal stone work (floor stone work) and 1 kg of glue should be used for every 1 square meter.
Stone glue is fireproof due to the presence of minerals and can withstand temperatures above +90 and -30 degrees Celsius without being deformed or brittle. It also has no contraction or expansion due to temperature changes.
In places with high traffic volume, carrying different weights, falling and throwing

It is resistant to weights and... and does not cause any damage to the surface connection.
To use glue, it is enough to use this material in the four corners and the center of the desired surface, and in general, about 10% of the desired surface space is covered by this material.
First, the first and second components of the desired glue are mixed equally, and we put the necessary amount on stone or concrete or metal form in five points.
If it is not mixed completely and correctly, it will not be effective and will always remain in the form of a paste.
The mixing ratio is one to one and the working time is 45 minutes.
