STRONG GLUES BUTAPREN GLUE FOR GENERAL APPLICATIONS PROPERTIES 1. Strong and flexible. 2. Waterproof. 3. Durable joints. 4. Excellent adhesion to surface. BUTAPREN STRONG is a glue manufactured based on chloroprene rubber, phenol resins, fillers and organic solvents. APPLICATIONS BUTAPREN is used for gluing synthetic and natural leather, rubber, textiles from natural materials, felt and combinations of these materials to each other. It is especially useful for gluing footwear, e.g. top of the shoe with the sole. The joints are resistant to ageing and water. The joints are also highly durable, flexible and have excellent adhesion to the surface. EXPIRY DATE: 6 months from manufacturing date. PACKAGING: tube: 75 ml, metal cans: 200 ml, 800 ml, 2.5L, 4.5L, 10L. EFFICIENCY: depending on the absorbability of the surface. STORAGE TEMPERATURE: from +5°C to +30°C.

Xn - Harmful. N – Toxic to the environment. Contains acetone, toluene, low-boiling unspecified naphtha. R38 - Irritating to skin. R48/20 - Harmful: danger of serious damage to health by prolonged exposure through inhalation. R62 - Possible risk of impaired fertility. R63 - Possible risk of harm to the unborn child. R67 - Vapours may cause drowsiness and dizziness. R50/53 - Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. S2 - Keep out of the reach of children. S9 - Keep container in a well-ventilated place. S16 - Keep away from sources of ignition - No smoking. S29 - Do not empty into drains. S51 - Use only in well-ventilated areas. During and after work ventilate the room until the characteristic odour is gone, after this time the room is ready to use. Protect against frost and exposure to sunlight. Store and keep in tightly closed containers. Follow the instructions on the container. See Material Safety Data Sheet for detailed information. Attestation of PZH (National Institute of Hygiene) PZH Attestation: HK/B/2509/05/98 METHOD OF USE SURFACE PREPARATION - Prior to starting any work the glue and joined elements must be brought to room temperature. - The surfaces to be glued must be dry, clean, free from dust (dirt), greasy stains, old loose joints and other contaminations that can impair glue adhesion. - The surfaces to be glued must be carefully cleaned, polished with abrasive paper and cleaned of any dust. - Wash the greasy spots with solvent or extraction naphtha. PRODUCT PREPARATION - The glue in the commercially available form is ready to use. - Mix thoroughly prior to use. - If the glue’s consistency changes due to excessively low storage temperature the glue must be heated up to +18°C to +25°C and mixed well prior to use. GLUING - All work must be carried out at a surface and ambient temperature of over +80C. - Apply a thin layer of glue to both glued surfaces using a brush with short and hard bristles. - In case of absorbent materials like leather, textiles, etc the glue must be applied twice in 20 minute intervals. - After approximately 20 minutes from the application of the last layer, the glued elements must be joined together and tightly pressed against each other for 10-15 minutes. - We recommend pressing the glued surfaces together for 5-10 minutes using 0.4 MPa of pressure (activated elements can be pressed for only 15 seconds). - In order to increase the joint strength (for example when gluing shoe sole to the top of the shoe) the rubber element with applied and semi-dried glue must be activated at approx. +550C for 3 min. - Activation can only be used with effectively operating ventilation far from a naked flame. - Joint flexibility depends on the applied pressure – the higher the pressure the higher the flexibility. - The joint reaches its full strength after 72 hours.
