LIONBOND環氧樹脂

積層，沾接，慣封 TECHNICAL INFORMATION MACROPLEXX© 5020 DESCRIPTION MACROPLEXX© 5020 is a two part A&B component system, which is fast setting when mixed via a static mix nozzle at room temperatures. Because it is a high viscosity non-sag material, the mixed material is ideal for all types of gap filling requirements on steel, aluminium, polycarbonates and general plastics. It is also very good on vertical surface bonds because it is an MMA Methacrylate it exhibits excellent structural strength even without priming the surfaces. Because of its macro structure the bonds formed show excellent durability high peel strength even in big gaps and excellent solvent and environmental resistance, resisting fuels, lubricants cleaning chemicals and fluids. TYPICAL USAGES OF MACROPLEXX© Structural joining of metals, plastics, composite bonding and on ceramics where high impact strengths are needed. Applications include wind turbine, vehicle roofs, fibreglass, sports goods, automotive spoilers, vents, housings.

MATERIAL SAFETY DATA SHEET 5020 1. IDENTIFICATION OF PRODUCT & COMPANY PRODUCT NAME - Macroplexx 5020 ACRYLIC ADHESIVE INTENDED USE - No relevant information SUPPLIER - HOLDTITE ADHESIVES LIMITED, NINTH AVENUE EAST, TEAM VALLEY TRADING ESTATE, GATESHEAD, TYNE & WEAR, NE11 0EJ. Emergency Tele - 0191 4914433 2. COMPOSITION / INFORMATION OF INGREDIENTS A blend of elastomers(s), methylmethacrylate resin(s), flexibliser(s), viscosity modifier(s), stabiliser(s), and pigment(s) For details of substances presenting a health hazard within the meaning of the Chemicals (Hazard Information & Packing) regulations 1993 see under Section 8 of this Safety Data Sheet. 3. HAZARDS IDENTIFICATION Prolonged contact with product may result in the removal of essential fats and may result in dermatitis unless good personal hygiene is used. May cause sensitisation by skin contact. Irritating to eyes respiratory system and skin - Flammable 4. FIRST AID MEASURES General: In all cases of doubt or when symptoms persist seek medical attention. Never give anything by mouth to an unconscious person. First Aid for Inhalation: Remove to fresh air, keep warm and at rest. If breathing is irregular or stopped give artificial respiration. Give nothing by mouth. If unconscious place in recovery position and seek medical advice. First Aid for Eye Contact: Contact lenses should be removed. Irrigate copiously with clean, fresh water for at least 10 minutes holding the eyelids apart, seek medical advice. First Aid for Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water or use a proprietary skin cleaner. Do not use solvents or thinners. First Aid for Ingestion: If accidentally swallowed obtain immediate medical attention. Keep at rest. DO NOT induce vomiting. 5. FIREFIGHTING MEASURES Extinguishing Media: Carbon Dioxide, Dry Powder, Sand, Foam, Water Spray Mist. NOT TO BE USEDSPECIAL INSTRUCTIONS FOR FIRE FIGHTING PERSONNEL - Fire will produce dense black smoke containing hazardous products of combustion (see Section 10.) Decomposition products may be a hazard to health. Appropriate self-contained breathing apparatus may be required. Cool closed containers exposed to fire with a water spray. Do not allow water run off from fire fighting to enter drains or water courses. 6. ACCIDENTAL RELEASE MEASURES Exclude sources of ignition and ventilate the area. Exclude non-essential personnel. Avoid breathing vapours. Refer to protective measures listed in sect.7&8.Do not allow large quantities to enter drains or water courses. If it does local water companies should be contacted, in case of contamination of streams or rivers or lakes the National Rivers Authority Contain and collect spillage's with non-combustible absorbent materials e.g. sand, earth and place in suitable container for disposal in accordance with the waste regulations. 7. HANDLING AND STORAGE Avoid skin & eye contact. For personal protection see sect.8. Good housekeeping and regular removal of waste materials will minimise risks. Observe the label precautions. Store between 5 & 25°C in a dry well ventilated place away from sources of heat, ignition and direct sunlight. No smoking. 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Engineering Measures - Provide adequate ventilation. Where reasonably practicable this should be achieved by the use of local exhaust ventilation and good general extraction. If extraction methods are insufficient to maintain concentrations of particulates and/.or solvent vapours below relevant OEL's, suitable respiratory protective equipment should be worn.

OES = Occupational Exposure Standard MEL - Maximum Exposure Limit. OEL's are from EH40 except where marked SUP which are assigned by the supplier of the substance. General Protection - All ppe, including rpe, used to control exposure to hazardous substances must be selected to meet the requirements of the COSHH regulations. Respiratory Protection - If exposure to hazardous substances identified above cannot be controlled by provision of local exhaust ventilation & good general extraction, suitable respiratory protective equipment should be worn. Hand Protection - Full physical protection is best. Seek relevant advice from glove manufacturers. Barrier cream may be of help but should not be applied after exposure has occurred. Eye Protection - Eye protection designed to protect to protect against liquid splashes should be worn. Skin Protection - Cotton or cotton/synthetic overalls or coveralls are normally suitable. Grossly contaminated clothing should be removed and the skin washed with soap and water or a proprietary skin cleaner. TDS 179 MSDS 179 MATERIAL SAFETY DATA SHEET 5020 9.
