GENERAL INFORMATION
The 88-Metal multi-purpose contact polychloroprene adhesive (TU 2513-022-13238275-01) is a solution of polychloroprene rubber, alkyl phenol and formaldehyde resins, modifiers, vulcanizing heaters in the mixture of ethyl acetate and solvent petroleum spirit.
PURPOSE
The adhesive is to be used in the production process, construction, and by individuals to glue to metal such materials, as rubber, natural and artificial leather, various polymeric materials, including rigid and plasticized PVC, fabric, wood, cardboard, foam rubber, and other porous and fibrous materials, as well as to glue the specified materials to each other in any combinations. Especially effective for gluing rubber based on natural, styrene and isoprene rubbers.
The product was permitted for application by the Center of State Sanitary and Epidomiological Control of Moscow.

BRIEF APPLICATION INSTRUCTIONS
Stir the adhesive thoroughly before use. The glued surfaces shoul be conditioned, degreased, and dried.
Cold Technique. Apply a uniform thin adhesive layer to the glued surfaces and leave to dry for 15-20 minutes, then apply another layer of adhesive and leave to dry for 10-15 minutes, after that press the surfaces tightly against each other. The glued item can be used after 24 hours.
Depending on the conditions of gluing and properties of the glued materials (porosity, strength, elasticity, etc.), the gluing method can be changed.
Hot Technique. Apply a thin adhesive layer to the glued surfaces and dry for 20-30 minutes, then heat the glued surfaces to 80-90°C, and press tightly against each other for 1 -2 minutes. The item can be used after 3 hours.
Use ethyl acetate to dilute the adhesive by its thickening as a result of the solvents' evaporation. Clean the instruments by a mixture of ethyl acetate and solvent petroleum spirit (Galosha) with the 1:1 volume ratio.
Storage conditions: store the adhesive in a tightly sealed container at the temperature from +10 to +40°C. At temperatures below +10°C the adhesive is jellified (i.e. becomes more viscous). In this case, it should be heated in warm water or a warm room to a temperature from +25 to +40°C and stirred thoroughly, after this the adhesive properties and consistency are fully restored.
Warranty shelf life - 12 months from date of manufacture.
