General information
Chloroprene adhesive (nairit) 88 is produced on the basis of nairit (chloroprene rubber) and a number of other components - nefras, ethyl acetate, phenol-formaldehyde resin. The mixture contains adhesive enhancers and a number of other synthetic resins.
The product is manufactured in accordance with GOST 12172-74. In appearance, the mass has a beige, brownish, greenish color. Precipitation is allowed, which does not reduce the basic properties.
Manufacturing plants produce glue in different packages - in small containers, in cans and sprays, in drums and barrels of 25 - 50 liters. Shelf life - 1 year, storage is carried out at temperatures -40...+30 degrees.
Glue 88 and all its varieties are of consistently high quality. Easy to apply to surfaces, easy to use.
The complex composition provides excellent adhesive properties, makes the glue waterproof, elastic, and some compositions are considered a particularly strong material. Each variety has its own characteristics and common features. For example, 88-NP glue can withstand low and high temperatures, while 88-M glue is very tear-resistant.
Types and their characteristics
Each type of glue 88 will have different technical characteristics. It is worth considering all brands that are in demand.
88-SA
Glue 88-CA is characterized by parameters of average tensile strength, the value is equal to 11 kgf/cm². Suitable for bonding rubber elements, metal bases, foam rubber, rubber with glass, wood, concrete and other bases. Actively used in shoe repair. The product is highly moisture resistant and retains surface adhesion during prolonged exposure to any liquid – fresh or salty. Able to retain its properties in cold and heat from -40 to +50°C.
The glue is distinguished by belonging to the explosion and fire category of substances, but is not toxic. It is forbidden to work with glue near sources of open flame, sparks and excessive heat.
Has the following advantages:

88-NT
Special-purpose Moment 88 NT glue glues surfaces made of absolutely any materials in structure and composition. You can use glue to hold fabrics and polymers together. It is capable of operating at various temperature conditions from -40 to +50°C. The adhesive base will remain sticky for a long period. However, after connecting the parts, adhesive characteristics will appear, and 6 hours after application, the base can already be used. This is considered one of the best indicators. The glue can be applied to the surface using any convenient of two existing methods.
88-M
88-M brand adhesive stands out noticeably on the market with its strength indicator of 15 kgf/cm², so you can safely choose it for various purposes. It was created on the basis of varieties 88-SA and 88-NP, which is superior in its characteristics. Surfaces glued with this substance can be used at air temperatures of -40...+70 degrees. The areas of application of this glue are quite extensive; it can be used in all of the above.
88-Metal
Universal adhesive 88 Metal is a high-quality, water-resistant product that has great adhesive strength. Any non-metallic parts can be attached to the metal base, including rubber, leather, fabric, wood, foam rubber and many others. The product is produced and is capable of providing ultra-strong connections between materials. The glue does not need to be diluted, especially with toxic drugs or toluene, since they are not contained in the composition. It is only permissible to dilute it with gasoline. 88 Metal is a type of adhesive based on polychloroprene rubber, and therefore is highly elastic.
Main product parameters:
- Viscosity 50 s.
- Fast hardening.
- Economical consumption.
- Significant strength of the adhesive seam.
- Consumption 0.1-0.2 kg/m², depending on the chosen application method.
- Curing time is 3 hours for hot application and up to 24 hours for cold application.
The composition is resistant to fresh and salt water and needs to be stored under conditions of 10 degrees Celsius or more. Before use, you need to keep it in a warm room for two days.
88-KR
This type of glue is the newest and most relevant among ordinary brands. The glue has improved strength, resistance to moisture and air, and has a reduced setting time. The finished adhesive joint will differ in its service life.
Important! The main component of the 88-K composition is chloroprene rubber. The glue can be diluted with gasoline, but other popular substances are not suitable for this. Glued surfaces can comfortably exist under environmental conditions of -50... +90 °C, which is much higher than other types of glue. The maximum possible strength value is 25-26 kgf/cm².
This type of adhesive is suitable for use in the automotive industry for the following purposes:

Using glue 88, you can glue car seat upholstery, trim the ceiling, doors, and other parts in the interior. In the furniture industry, the material is suitable for assembling individual units and attaching fabrics. The product is intended for gluing shoe soles, gluing fasteners, and insoles. In construction, glue is used for interior decoration - attaching floors, carpet, moldings, ceiling tiles.
Composition of the product
The main feature of glue 88 is its ability to glue a wide variety of surfaces, such as:
- wood;
- cardboard;
- dense fabrics and leather;
- rubber;
- porcelain and ceramics;
- glass and mirror.
Glue 88 is a truly universal composition that is equally effective for carrying out minor repairs at home and in industrial areas - it is no coincidence that it is actively used in shipbuilding and mechanical engineering, as well as in light industry. Glue 88 is heat- and water-resistant, it is characterized by plasticity and a high setting speed.
Another undoubted advantage of the composition is its anti-corrosion ability, which allows it to be widely used when working with metal products. The glue is quite easy to apply and is economical in use. So, for 1 square meter of the treated surface, only 300 mg of the composition is needed. The product is distinguished by its structural resistance. The product retains its technical characteristics unchanged under conditions of adverse effects of moisture, temperature changes and UV radiation.
Glue 88 is a thick mass of beige or greenish-gray color, and its shades may vary. The adhesive contains chloroprene rubber, ethyl acetate, nefras solution and phenol-formaldehyde resin. The presence of these components determines the adhesive’s resistance to diesel fuel and gasoline products, as well as the optimal setting speed. From application to gluing you only need to wait 3 to 5 minutes. During this time, you can move the surfaces to be glued if they were not initially fixed exactly.
88 Luxe adhesive is based on a synthetic rubber polymer or a natural rubber mixture to which phenol and formaldehyde are added. Such a structure is characterized by particular complexity. Based on these numerous molecular compounds, the uniqueness of the product can be characterized. It is characterized by elasticity and water resistance.

Instructions for use
Before use, any brand of product must be thoroughly mixed to ensure uniformity. How to use the glue and what to dissolve if it has thickened is always indicated in the specific instructions for use. Most types of glue can be dissolved with ethyl acetate up to 1:1. How to dilute glue in the presence of organic solvents? This is xylene or toluene, in some cases gasoline is suitable. You can use a 1:1 mixture of Galosh brand solvent and gasoline.
Before gluing, surfaces should be cleaned of dirt, dust, degreased and sanded. There are two ways to use:
- Hot. Apply the product in a thin layer, dry for half an hour. Then fold the surfaces and heat at +90 degrees for 10 minutes. Then wait at least 3 – 5 hours before using the product.
- Cold. Apply a thin layer of glue, dry for 15 minutes, then apply another layer. Press the parts down and dry for 24 hours at room temperature.
Please note that on porous materials it is necessary to apply a primer before gluing. What it is and which brand to choose is indicated in the instructions. Priming will help reduce the absorption of the adhesive.
