Polyurethane hardener
The most important hardener used in polyurethanes is hardener
Desmodur N75
After the reaction of hardener and resin, which is an exothermic reaction and does not require heat to continue, and the result of this reaction is a stable material that is used in many industries such as flooring and protective coatings for pipes and metal structures and many others.

Epoxy flooring
It is one of the products of Farapooyesh which is produced on the basis of epoxy bisphenol A and hardener polyamine resin. Suitable and high quality and features as follows have many customers and is one of the main products of the company.
Excellent rolling property that creates smooth, undulating surfaces. It does not bubble due to having quality anti-bubble material. Due to the lack of inactive solvents, its strength and scratch-resistant properties are excellent. They do not catch fish due to high quality materials and advanced formulation. Its surface is not distorted due to its quality materials and proper formulation. It can be supplied in various colors according to the order. Can be ordered in relatively small quantities. It is very hard and does not get scratches easily.
Epoxy floor primer
:Epoxy primer
The first step is to clean the floor with epoxy flooring, which is done in different ways according to its dirty condition, after which the floor should be sanded for as much cleaning as possible and to create suitable scratches and scratches. After completing these two steps, primer coating should be done on the floor. In this stage, dilute epoxy liquid with high permeability should be poured on the floor with good adhesion after drying to be able to insulate the surface in terms of moisture passage with the necessary strength and create High adhesion surface to protect the next layer from the separation of the floor in the future. Therefore, the life and durability of the floor directly depends on the quality of the primer and choosing the right type of primer and dryness and cleanliness of the surface when doing it is very important. Epoxy floor primers They are mainly divided into the following two groups:
Epoxy Polyamide Flooring Primer: EPD-01
This primer is produced and presented based on bisphenol () and hardener polyamide () resin. In the production of this product, a special composite solvent is used, which reduces the viscosity of the product to increase its penetration into concrete and substrate. This product has a very good adhesion to the floor and the subsequent layers adhere well to it, and also due to its good flexibility, it does not crack or break.
EPN-06 Epoxy Polyamine Flooring Primer
This type of primer is produced and presented on the basis of bisphenol () and polyamine () hardener resin and its viscosity is reduced by a special solvent and penetrates the concrete surface and hardens after hardening of the concrete surface. This product is mostly sensitive to floor moisture. It is used in very dry places and special places and its surface becomes hard and brittle due to being more expensive and also the above mentioned cases. In most places, polyamide primer is used for epoxy flooring.
Antistatic and conductive flooring materials
Static electricity generated by the movement of people and sparks caused by it can be dangerous in many places and cause heavy financial and human damage, so due to this issue in hospitals in operating rooms and ICU for Prevent potential errors and damage Conductive flooring equipment, which is more conductive than antistatic flooring, is installed and installed. In addition, in many factories where sparks can cause explosions, antistatic or conductive flooring is used to prevent this danger. Due to the importance of the issue of using quality materials for flooring, it is of special importance to be able to direct static electricity from our body through the floor and then copper strips to the well.
Antistatic and conductive floor coverings and primers of Farapoosh Company with the following outstanding properties are formulated with the best raw materials and can meet all the standards of these floors.
The materials of these floors can be produced and ordered with the following codes
Antistatic, conductive floor primer: ………… ..
Antistatic floor covering: ………….
Conductive flooring: ………….
Epoxy resin
Resins used in the flooring industry are mainly divided into the following two main groups
Resins used in floor primers that are used with polyamide hardeners
Resins used in veneers and floor coverings, which are mainly used with polyamine hardeners, and the most popular is 828 resin.
Hexion Company, which is very famous due to its low viscosity and excellent adhesion, and chemical resistance.
It is very good and in dry weather it has little sensitivity to temperature changes and its mechanical properties do not change over time.
Resins that can be provided in translucent floors with 828 resin or its quality equivalent.
Polyurethane resin
Polyurethanes are polymers that have a urethane bond. This bond is formed by incremental adsorption between an isocyanate group and an active hydrogen compound. Isocyanate groups are highly reactive and therefore do not require an increase in temperature to advance their reaction. Polyurethane resistance to abrasion, impact and cracking is very good and hardens at ambient temperature and its resistance to sunlight is much higher than the epoxy group.
انواع هاردنر اپوکسی
هاردنرهای اپوکسی
هاردنرهای مورد مصرف در صنعت کفپوش عمدتا به دو گروه عمده اصلی زیر تقسیم میشوند
هاردنرهای پلی آمید : این گروه از هاردنرها عمدتا در رنگهای اپوکسی و پرایمر کاربرد داشته و بدلایل خصوصیات مناسب زیر استفاده گسترده ای دارند : انعطاف پذیرند مقاومت بالا نسبت به ضربه و مواد شیمیایی دارند و بدلیل چسبندگی بالا به بتن و مقتاومت مناسب به رطوبت در صنعت کفپوش عمدتا بعنوان هاردنر پرایمر مورد استفاده قرار میگیرد .
هاردنرهای پلی آمین
IHهاردنر پلی آمین این هاردنرها بسیار در صنعت و بخصوص صنعت کفپوش کاربرد داشته و برای روکش و لایه های کفپوش استفاده میشود این هاردنر بامقاومت شیمیایی نسبتا خوب معمولا در لایه ها و روکش استفاده میشودو رزین پس از خشک شدن بسیار سخت گردیده ودر دمای اتاق خشک میگردد
رقیق کننده کفپوش پلی یورتان
این رقیق کننده ها در واکنش شرکت نکرده و فرار میباشند و معمولا تبخیر بالایی داشته و بایستی حتی الامکان استفاده نگردند ولی در بسیاری از پروژه ها استفاده از آنها جهت کاهش ویسکوزیته ضروری است و میبایستی در حد محدودی استفاده گردند استفاده بیشتر از حد مجاز آن مشکلاتی را بو جود میآورد که بایستی به آنها توجه گردد از جمله میتوان به کاهش استحکام نهایی پس از خشک شدن ، خطر آتش سوزی ،تبخیر و خطر تنفس و مسمومیتهای ناشی از آن از اهمیت بالایی برخوردار است.
