Some Facts about Lask Adhesive Lask is an inorganic adhesive based on alkaline aluminosilicate binder. In according to the type of modification, it can purchase different shades of color: from light pink to dark brown or grey. Lask Adhesive is not emitting toxic substances. Therefore, it doesn’t injure human health in the plywood, fiberboard and chipboard production process. It is absolutely safe for industrial and house use. Lask adhesive -glued furniture items keep harmlessness and material properties in the course of long-term exploitation. Lask Adhesive has been thoroughly tested for over 20 year. Lask Adhesive is manufactured in accordance with Ukrainian normative documents and is approved by the health safety authorities of Ukraine for the use in civil engineering. Lask Adhesive is determined by good adhesion to materials of various origins, such as: cellulose-containing materials (wood, veneer sheet, sawdust, wood chips and shavings, jute cloth etc.); silicate materials, including different types of concrete (besides, Lask Adhesive improves durability of the pervious concrete); ceramics; natural gravel (granite, marble); glass and fibreglass; metal (steel, cast iron); mineral wool insulation materials.

Class of water resistance of wooden structures D1 (requires external protection) D3-D4 D1-D4 Lask Glue Creation History Few years ago Ukrainian scientists invented the formula of universal mineral binder which has become a basis for further development of adhesive compositions. Lask Glue became one of them. It is used in wooden products and furniture details manufacturing. Lask Adhesive-glued furnishings don't cause damage to environment or human health because of zero free formaldehyde content. read more People are constantly in danger of surroundings, modified by their vital activity. Moments of our life are accompanied by the impact of chemical compounds that are “hidden” inside floor, ceiling, furniture, and even at the nurseries. Nowadays furniture for schools, kinder gardens, other educational institutions are made using toxic substances, which can harm human body irreparably. Hotel rooms, hospital wards and business centers furniture aren`t an exception too. In case of even the slightest fire poisonous gases, evaporating from burning items, murder people quicker than the flame. Household goods release chemical compounds into the atmosphere causing dangerous diseases over time, if there is no fire too. The cause of these illnesses usually remains unknown… even mysterious! The list of surrounding threats which constitute the articles of everyday use is endless. POLVAX-Ukraine LLC invested resources into the final phase of the mineral adhesive formula research. The last testes confirm that the Lask Glue satisfy all safety and technology requirements. So, the company signed a license agreement and now he owns the exclusive right to manufacture the product. A little later the responsibility for the implementation of innovative safe mineral adhesive was conferred on LASK-K LLC by the main investor company and its associates. Lask Glue was created for the manufacture of organic grades of eco-friendly plywood, fiberboard, chipboard and other building materials having zero emission. Lask is fireproof glue which bonds safely! close Fields of Lask Glue Application The Lask adhesive is applied for production of nontoxic structures, intended for installing in living or working space where requirements to an ecological state and fire safety are increased. Among them are closed rooms with limited quantity of exits, nurseries, classrooms, lecture halls, hospital wards, hotel or offices rooms etc. Cutting the ready items Fabrication Mode of Application Cleaning Health safety Destruction Mode of Application Lask Adhesive consists of two components: 1) liquid component А; 2) solid component B (catalyst). To prepare adhesive two components must be mixed in proportions prescribed by manufacturer: approximately 3/5 weight parts of component А and 2/5 weight parts of component B. Component A is packaged into the sealed metal or plastic containers which have capacity of 4, 6 or 20 kg, buckets, canisters, plastic cubes for transportation of chemical substances or cisterns. Component B is packaged in sealed multilayer paper bags which have capacity of 2, 3, 10 or 25 kg and in Big Bags (500 or 1000 kg). Other types of packing may be also discussed with the managers.
